3 Phase UPS overview The HP 3 Phase UPS protects your sensitive electronic equipment from the most common power problems including power failures, power sags, power surges, brownouts, and line noise.

Power outages can occur when you least expect it and power quality can be erratic. These power problems have the potential to corrupt critical data, destroy unsaved work sessions, and damage hardware - causing hours of lost productivity and expensive repairs.

With the HP 3 Phase UPS, you can safely eliminate the effects of power disturbances and guard the integrity of your equipment. The HP 3 Phase UPS is designed for critical applications such as ultra high—density blade servers in a data center environment.

Providing outstanding performance and reliability, the HP 3 Phase UPS unique benefits include:

• High-density three-phase input, three-phase output UPS

• Scalable to 60 kW (redundant N+1 configuration) by connecting up to six additional parallel UPS modules.

Each UPS in the parallel system connects to a Power Bus Bar pre-installed in the rear of a rack. Racks can be configured for bottom or top entry

A Parallel UPS Card in each paralleled UPS provides connectivity for system metering and operational mode control. In a parallel system not fully loaded, the system will shift load to UPSs with the strongest batteries or additional ERMs to maximize runtime when on battery. Parallel systems can be configured for capacity or redundancy.

• 6U UPS height, 3U ERM height

• Normal operating mode that minimizes heat generation by operating at typically >98% efficiency

The UPS filters incoming AC power and provides consistent power to your equipment without draining the battery.

• For utility line input that exceeds normal operating range, automatic transfer to an online, double-conversion, high-frequency UPS design with pure sine wave output and power-factor correction

• EBM technology that uses advanced battery management to increase battery service life, optimize recharge time, and provide a warning before the end of useful battery life

• Extended runtime with up to four ERMs per UPS

• Hot-swappable electronics module and batteries that simplify maintenance by allowing you to replace them safely without powering down the critical load

• Emergency shutdown control through the REPO port

• HP UPS Management Module for network connectivity with monitoring and control

• Firmware that is service upgradeable through the standard DB-9 communication port

• Backed by worldwide agency approvals


The Power Bus Bar for parallel systems, mounted in the rear of an HP rack, provides the required input and output connections for the paralleled UPSs and has a single system-rated input connection. The parallel UPS system can be installed with Output Power Modules or connected to rack-mounted power distribution systems.

Note these guidelines when configuring the UPS standalone unit or parallel system:

• There is a maximum of four ERMs per UPS.

• Mount ERM(s) for a standalone UPS directly below the UPS or, with rack side panels removed, in an adjacent rack to the left of the rack containing the UPS.

• Mount ERMs for a parallel system in an adjacent rack to the left of the rack containing the UPSs (rack side panels removed).

• For consistent runtimes, each UPS in a parallel system should have the same number of ERMs.

• Some load equipment may require phase rotation or phase relationship coordination to ensure proper operation. Review your equipment manufacturer’s power requirement documents to ensure that your connected equipment operates correctly.

NOTE: For proper UPS operation, be sure that the terminal block jumpers are inserted as shown.

REPO port

WARNING: The REPO circuit is an IEC 60950 safety extra low voltage (SELV) circuit. This circuit must be separated from any hazardous voltage circuits by reinforced insulation.


CAUTION: • Do not connect the REPO port to any utility connected circuits. Reinforced insulation to the

utility is required. The REPO switch must have a minimum rating of 24 Vdc and 20 mA and be a dedicated latching-type switch for the 3 Phase UPS only, no other device or circuit including a single phase UPS. The REPO signal must remain active for at least 250 ms for proper operation.

• To ensure that the UPS stops supplying power to the load during any mode of operation, the input power must be disconnected from the UPS when the EPO function is activated.

NOTE: For Europe, the emergency switch requirements are detailed in Harmonized document HD-384-48 S1, “Electrical Installation of the Buildings, Part 4: Protection for Safety, Chapter 46: Isolation and Switching.”

The UPS includes an isolated REPO port. When properly wired, the REPO feature allows the power at the UPS output receptacles to be switched off from a remote location. When REPO is activated, the UPS powers down all converters, de-energizes all system relays, trips the UPS battery circuit breaker, and powers down within 10 to 15 seconds. However, the unit continues to have logic power (the display is still active) and is not fully powered down until input power is disconnected from the unit. This feature can be used for powering down the load and the UPS by thermal relay, for example in the event of room overtemperature.

To use this feature, the REPO port must be connected to a remote switch (not supplied). The REPO switch is used in conjunction with a main disconnect device that removes the AC source from the input of the UPS. When the switch is activated:

• The REPO feature immediately powers down protected devices and does not utilize the orderly shutdown procedure initiated by power management software.

• The REPO feature shuts down UPS units operating under either utility or battery power.

Keep the REPO connector installed in the REPO port on the UPS even if the REPO function is not needed. The REPO connection are listed below:

Wire function Terminal wire size rating Suggested wire size

L1 4–0.32 mm2 (12–22 AWG) 0.82 mm2 (18 AWG)

L2 4–0.32 mm2 (12–22 AWG) 0.82 mm2 (18 AWG)

There are two REPO positions, normally-open (NO) or normally-closed (NC). The pins on the NC REPO connector are connected together. When this connection is open, the logic circuitry completely shuts down the UPS, thus preventing the power from supplying the load. To use NC REPO, remove the jumper wire and connect an NC external switch. To use NO REPO, connect an NO external switch. For REPO locations, see Connecting REPO port .

NOTE: If the UPS was operating on battery power when the remote switch was closed, no power is available to the load devices until utility power is restored and the UPS has been manually powered up.

To restore power to the load devices after the REPO feature is activated, press the Power On button after the AC source is reconnected to the UPS.

IMPORTANT: Pressing and holding the Power On button without utility present normally initiates a battery start and the UPS assumes the load. However, if the Power On button is pressed and a REPO is detected, battery start is inhibited and the UPS is not able to assume the load. The electronics module fan spins and the Alarm LED and an audible alarm are active as long as the Power On button is held.

Installing in a parallel configuration WARNING: This equipment must be installed by a licensed electrician or trained service personnel familiar with high-power circuitry

A UPS connected to a Bus Bar with a paralleling line cord is identified as a member of the parallel system. The Bus Bar connects the line and load to a common power bus. A parallel system can be configured for capacity or redundancy.

The UPS models in a parallel configuration require a dedicated branch circuit that meets the following requirements:

• Circuit with overcurrent protection, depending on parallel configuration:

Number of UPSs in parallel system

HP 3 Phase NA HP 3 Phase INTL

3 150 A 75 A

4 200 A 100 A

5 225 A 125 A

6 (N+1 system) 225 A 160 A

• Three-phase, 4-wire plus ground, 208 Y/120 V nominal (NA) or 400 Y/230 V nominal, 380-415 VACacceptable (INTL)

• 50/60 Hz

• The breaker must be wall-mounted and be readily accessible to the operator

• Flexible or rigid metal conduit

Installing the input and output wiring Be sure that the UPSs are properly installed in individual rail kits in a rack containing a Bus Bar.

IMPORTANT: The UPS is a transformerless UPS that requires an unbroken neutral from the AC

source. Installations with an upstream generator or dual source ATS that will open the neutral (4

pole) will require either an isolation transformer in front of the UPS, or a 50 mS overlap of the

different source neutrals during the transition.

Preparing to install the hardware Before installing the hardware:

1. Be sure the necessary tools and materials (on page 13) are available.

2. Select an installation site ("Selecting a site" on page 14).

3. Prepare the equipment ("Readying the equipment" on page 14) for installation in the rack.

Tools and materials The following tools are required for installation:

• Phillips screwdriver

• 10-mm hex-nut wrench

• T-25 Torx driver

A cage nut-fitting tool is supplied with the rack.

Selecting a site

WARNING: To prevent fire or electric shock, install the unit in a temperature- and humidity-controlled indoor environment, free of conductive contaminants.

When selecting a site, consider the following factors:

• Elevated operating ambient temperature—If the equipment is installed in a closed or multi-unit rack assembly, the operating ambient temperature of the rack environment might be greater than room ambient temperature. Install the equipment in an environment compatible with the operating temperature ("Environmental specifications" on page 103).

• Reduced air flow—In the rack, the rate of air flow required for safe operation of the equipment must not be compromised.

• Circuit overloading—Consideration should be given to the connection of the equipment to the supply circuit and the effect that overloading of the circuits might have on overcurrent protection and supply wiring. Appropriate consideration of equipment nameplate ratings should be used when addressing this concern.

• Reliable earthing—Reliable earthing of rack-mounted equipment should be maintained. Particular attention should be given to supply connections other than direct connections to the branch circuit, such as the use of power strips.

• Electrical requirements—All models require a dedicated (unshared) branch circuit, suitably rated for the specific UPS as stated in "Input specifications" .

ERM installation 56

Readying the equipment 1. Check the battery recharge date specified on the label that is affixed to the shipping carton.

IMPORTANT: Do not use the battery if the recharge date has passed. If the date on the battery recharge date label has passed without the battery being recharged, contact an HP authorized service representative for directions.

UPS operations

Mimic screen The Mimic screen shows the internal components of the UPS and a real-time display of the operating status.

A thicker bar indicates that the node is energized.

Modes of operation The UPS has four modes of operation:

• Standby mode (on page 64)

• Normal mode (on page 65)

• Battery mode (on page 66)

• Auto-Bypass mode (on page 66)

Standby mode In Standby mode:

• No power is available at the UPS output receptacles.

• The UPS charges the batteries as necessary.

The UPS can be placed in Standby mode when the UPS is in Normal mode (on page 65).

To place the UPS in Standby mode:

1. Power down the UPS.

UPS operations 65

o Standalone UPS configuration—See "Powering down the standalone UPS (on page 72)."

o Individual UPS in a parallel configuration—See "Powering down an individual paralleled UPS (on page 72)."

o Parallel UPS configuration—See "Powering down the parallel system (on page 73)."

2. Power to the load ceases.

IMPORTANT: While in Standby mode, the UPS maintains the charge on the batteries, but no power is available at the output receptacles. The UPS remains in Standby mode until an alternate mode is selected or until utility power is removed.

Normal mode In Normal mode:

• Power is available at the UPS receptacles.

• The UPS charges the batteries as necessary.

Depending on input power conditions, the UPS automatically changes modes. The UPS has three types of Normal mode:

• Standard mode (on page 65)

• Full-Time Standard mode (on page 65)

• High Efficiency mode (on page 65)

Standard mode If the input line exceeds normal operating range, the UPS transfers to Standard mode (Online mode) to produce a regulated output voltage. When the input line returns to normal operating range, the UPS returns to High Efficiency mode (on page 65).

Full-Time Standard mode Full-Time Standard mode (continuous Online mode) is user selectable for full-time operation.

High Efficiency mode By default, the UPS operates in a High Efficiency mode that minimizes heat contribution to the rack environment. The system bypass input directly supplies the system output with three-phase AC power, and the UPS automatically transfers to double-conversion (Normal mode (on page 65)) operation as needed. The battery recharges as necessary.

Continuous double-conversion mode Continuous double-conversion mode is available only for loads less than 10 kW (86%). If the load exceeds the 10 kW limit while in Standard mode, the UPS switches to High Efficiency mode until the load is reduced below 9 kW. After three attempts within one hour to operate in Standard mode, the UPS locks into High Efficiency mode for one hour to prevent continuous cycling.

UPS operations 71

Running automatic battery tests Battery tests rely on backfeeding the utility, using the utility as a load. Some sites might choose to disable battery testing if their source is not capable of being backfed. Examples of such sources include generators, other UPSs, and other stiff or soft sources. If a source is not capable of being backfed, the UPS aborts the test (due to utility failure) and maintains the load and log the event. Further consequences depend on the source (for example, another UPS feeding the BladeUPS module might trip off).

NOTE: For automatic and manual battery tests, the UPS determines when it is appropriate to run the test. Battery tests run only when the system is in High Efficiency mode.

To disable battery testing:

1. Press any button on the front panel display to activate the menu options.

2. Select SETTINGS > USER SETTINGS > BATTERY SETUP > Battery Low Alarm.

3. Use the up or down arrow buttons to select Disabled.

4. Press the left arrow button to save the setting.

5. Press and hold the ESC button until the Start screen appears.

Testing the front panel display To test the LEDs:


2. Select CONTROL, DISPLAY TEST

3. Confirm the selection by pressing the right arrow button.

Press ESC to stop the test.

Silencing an audible alarm To silence an alarm, press any button on the front panel display to silence the alarm. If the alarm status changes, the alarm beeps again, overriding the previous alarm silencing.

IMPORTANT: • Although the audible alarm silences, the condition that caused the alarm to sound may still

exist. • If a utility power failure caused the alarm, the alarm silences after power is restored.

For information about audible alarm conditions, see "LED and audible alarm troubleshooting (on page 94)."

Verifying the REPO port connection

NOTE: While testing, operate connected equipment in a safe test mode so the effects do not disrupt critical operations.

After connecting the REPO port (on page 21):

1. Initiate a REPO by closing the REPO contact.

Control terminals The cables should be connected to the control terminal with a mating connector. Input and output terminals have a functional isolation from terminal to terminal. They are connected to the UPS chassis through individual 1 MW resistors.

If using a semiconductor switch type, pay attention to the proper polarity. A relay or other mechanical control is preferred.

Relay output contacts

WARNING: The relay output contacts must not be connected to any utility connected circuits. Reinforced insulation to the utility is required. The relay output contacts have a maximum rating of 30 VAC/1 A and 60 Vdc/2 A nominal values.

Communication 77

The UPS incorporates a programmable relay output with potential free contacts for remote alarm indications. An additional four relay outputs can be obtained with the compatible Relay Interface option card.

Programmable signal inputs The UPS incorporates two programmable signal inputs. HP recommends using non-polar (relay) control input. The pins must be shorted with maximum resistance of 10 ohm in order to activate the specific input.

Verify control terminal connections if polarity control is required.

Signal Description

empty Not in use (default)

building alarm 1-2 These alarms can be activated separately or at the same time with other building alarms. Building alarms are local only to the UPS.

on generator If active, the High Efficiency setting is disabled (BladeUPS 12i model only) and battery tests are disabled.1

ext battery breaker If active, the UPS knows that the external batteries are disconnected.2

request bypass If active, the UPS transfers the load to bypass when the bypass voltage, frequency, and phase rotation are within the allowed limits.1

force bypass If active, the UPS is forced to static bypass operation regardless of the bypass status.1

on/OFF If active, the UPS output powers down regardless of the mode of operation. Auxiliary power, communication, and rectifier/battery charger remain functional. Restart is initiated immediately when the signal is inactive.2

charger off If active, the battery charge function is disabled. In a utility power outage, the discharge of batteries is supported.2

1 Program for only one UPS in a parallel system. 2 Program for all UPSs in a parallel system.

Use the programmable signal inputs to emulate some of the features usually seen on larger 3-phase systems. For example:

• Configure the signal from a smoke detector or water leak detector to power down the system.

• Configure a vibration sensor or air conditioner sensor to power down the system.

• Set actions for alarms from a generator, such a disabling the charger for an undersized generator or shutdown for a failed generator.

• Configure an ATS sensor to transfer the system to Auto-Bypass mode.

Parallel communication The Parallel UPS Card in each paralleled UPS provides connectivity for system metering and operational mode control. Powering up, powering down, and auto-calibration commands given at one UPS also command the other UPSs in the parallel system. The UPSs in a parallel system are in constant communication to monitor settings and status information.

Communication 78

Mode transfers • If one UPS in a parallel system transfers from High Efficiency mode (on page 65) to Normal mode (on

page 65), the other UPSs transfer also.

• If one UPS transfers to Battery mode (on page 66), the remaining UPSs in the parallel system stay online. The transferred UPS might transfer back to online at any time, and the parallel system resynchronizes.

• When a parallel system is on battery power , the front panels of each UPS display the battery status information of the UPS with the lowest runtime remaining. When the first UPS shuts down, the other UPSs also shut down.

• In a parallel system configured for redundancy, the UPSs use a distributed bypass, and the following alarms cause an individual UPS to power down instead of transferring to Auto-Bypass mode (on page 66):

o Failure of the fan, fuse, temperature sensor, or power supply

o Inverter AC under voltage

o Battery current limit

o DC line under voltage

o Battery over voltage

Redundant signal wiring The redundant signal wiring provides redundant backfeed protection in case of Parallel UPS Card failure in the parallel system. If the card fails, the UPSs transfer to Normal mode (on page 65). The system runs unsynchronized, and any UPS can transfer to Battery mode (on page 66) as necessary. If any UPS must transfer to Auto-Bypass mode (on page 66), the redundant signal wiring allows the entire parallel system to transfer to Auto-Bypass mode, without backfeeding.

Auto-identification The UPS parallel system automatically assigns identities to each UPS in the system. To take advantage of this feature, wire the Parallel UPS Cards together. For more information, see "Installing in a parallel configuration (on page 26)."

Upon powering up the UPS, the UPS with the initializing jumper installed identifies itself as UNIT 1. The next UPS wired identifies itself as UNIT 2, and so forth. The auto-identification sequence takes about 15-20 seconds to complete after all the UPSs in the parallel system have logic power.

If a UPS is powered down or otherwise loses logic power, the UPS re-identifies itself in the proper sequence after logic power is restored.

If a UPS is powered down and removed from the parallel system, the other UPSs in the system do not re-identify themselves to compensate for the missing UPS until logic power to all the UPSs is cycled. For example, if you remove UNIT 2 and rewire UNIT 3's Parallel UPS Card IN port to UNIT 1's Parallel UPS Card OUT port, UNIT 3 does not re-identify itself as UNIT 2 until logic power is cycled. The Parallel UPS Cards for UNIT 1 and UNIT 3 continue to function normally without the need to re-identify.

Communication 79

Metering The Output and Load Receptacle meter readings differ between a parallel system and a standalone UPS. In a parallel system, one UPS reads the Load Receptacle value for the total system (the others read zero), but each UPS displays its own Output value. For example, in a two-unit parallel system with one Anderson load connection for 12 kVA, the Load Receptacle current would read 12 kVA on one UPS and zero on the other UPS, but the Output measurement would be 6 kVA on each UPS (half the total). In a standalone UPS, the load can be connected from the outlet cord or the Anderson load connector. The Output measurement would be the total load on the UPS, and the Load reading would be the portion supplied by the Anderson load connector.

Power management 80

Power management

HP UPS Power Protection Agent overview The HP UPS Power Protection Agent runs on a local or network server and allows the management module to gracefully shut down the operating system of that server and optionally run a script during power failure. Install the agent on any machine that is powered by the UPS and any machine that the management module uses to initiate a command.

NOTE: If you are an existing HP Power Manager user, you must uninstall the HPPM Remote Agent before installing the UPS Power Protection Agent.

Features • Monitors the status of the UPS and performs diagnostics

• Manages a graceful shutdown of attached equipment during a utility power failure

• For UPSs with multiple load segments, the management module, manages independent UPS load segments to provide separate power control of connected equipment

Action:

Troubleshooting 97

1. Verify the bypass utility.

2. Check for one of the following alarms:

o Bypass over or under voltage

o Bypass over or under frequency

o Bypass unavailable

Check Parallel Board condition Possible cause: The UPS does not recognize another paralleled UPS.

Action:

1. From the UPS Status menu, select the Units on Parallel Card option and be sure that all UPSs appear in the list.

2. If any UPS is missing, verify the Parallel UPS Card connections and recheck the status from the UPS front panel. See "Configuring the Parallel UPS Card (on page 41)."

3. If all UPSs appear in the list, verify the redundant signal wiring (on page 78) connections.

4. Set the system to Auto-Bypass mode (on page 66).


Configuration error and UPS does not start Possible cause: The UPS failed to identify itself as a paralleled UPS within two minutes after utility power was applied.

Action:

1. Verify the Parallel UPS Card wiring connections. See "Configuring the Parallel UPS Card (on page 41)."


Phase rotation verification Action: Before installing the UPS, an electrician must check the phase rotation. The rotation should be A, B, C, or X, Y, Z.

Power is not available at the UPS output receptacle Possible cause:

• The UPS is in Standby mode (on page 64).

• the REPO switch is active or the REPO connector is missing.

Action:

1. Reset the REPO switch

2. Verify the REPO port connection ("Verifying the REPO port connection" on page 71).

3. For 12kVA models, be sure that the output circuit breaker is in the On position.

Troubleshooting 98

4. To supply power to the connected equipment, power up the UPS.



Protected equipment is not on Possible cause: The UPS is operating normally, but some or all of the protected equipment is not on.

Action:

• Be sure that the equipment is plugged into the UPS receptacles.

• Be sure that the output circuit breaker is in the Off position.

Overload condition Possible cause: Power requirements exceed the UPS capacity. For output overload ranges, see "UPS output specifications (on page 103)."

The alarm resets when the conditions becomes inactive.

Overtemperature condition Possible cause: The UPS internal temperature is too high, or a fan has failed.

Action:





2. Allow the UPS to cool:

a. Clear vents and remove any heat sources.

b. Be sure that the that the airflow around the UPS is not restricted.

3. Wait at least 5 minutes and restart the UPS.


Redundancy loss due to overload Possible cause: The specified power rating of the parallel system has been exceeded.

Action:

The load is supported, but the system lacks redundant protection while the overload condition persists.

Troubleshooting 99

Remove one or more load devices to reduce the power requirements.

Selective trip Possible cause: The UPS detected an internal fault.

Action: If the condition persists, contact an HP authorized service representative.

Site wiring condition Action: Contact a qualified electrician to be sure that:

• The line and neutral wires are not reversed in the wall outlet.

• A ground wire connection does not exist.

UPS detects software incompatibility Possible cause: The UPS detects a paralleled UPS with a later firmware version. Mixing major firmware versions is not supported. For minor software versions, the alarm does not prevent operation, but different firmware versions in a parallel system cause conflicts.

Action: Verify that all UPSs in the parallel system have the same firmware version. To update the firmware, see "Updating the UPS firmware (on page 91)."

UPS does not power down Possible cause: The batteries or electronics module is being replaced.

Action:

1. Complete the replacement procedure.





UPS does not power up Action:

1. Be sure the main utility circuit breaker is in the On position.

2. Check the power source at the utility power receptacle.

3. Be sure that the normally-closed REPO is closed, and that the normally-open REPO is open.

4. If replacing the batteries or electronics module, complete the procedure before powering up the UPS.



Troubleshooting 100


6. Contact a qualified electrician to check the power cord connections.

UPS does not provide the expected backup time Action:

1. Be sure that the battery circuit breakers are in the On position.

2. Allow the UPS batteries to charge for 48 hours.


UPS does not transfer to Auto-Bypass mode Action:

• Verify the bypass utility. The UPS is receiving bypass utility power that might be unstable or in brownout conditions.

• Be sure that the Usage of Bypass user setting is enabled. For more information, see "Changing user settings (on page 68)."

UPS is on battery Possible cause: A utility failure has occurred, and the UPS is in Battery mode (on page 66).

Action: The UPS is powering the equipment with battery power. Save files and shut down connected equipment.

UPS is on bypass Possible Cause: The UPS is in Auto-Bypass mode (on page 66).

Action:

The equipment transferred to bypass utility power. Battery mode (on page 66) is not available and the equipment is not protected; however, the utility power continues to be passively filtered by the UPS.

Check for one of the following alarms:

• Overtemperature

• Overload

• UPS failure

• Hot swap

• REPO

Pre-Failure Battery Warranty The Pre-Failure Battery Warranty, standard on all UPS units, extends the advantage of a 3-year limited warranty by applying it to the battery before it actually fails. The Pre-Failure Battery Warranty ensures that the battery is replaced free of charge when a notification that the battery might fail is received from power protector software. The battery warranty coverage is 3 years for parts. The warranty for the first year of ownership includes parts and labor. If battery spares are not available for a particular UPS model, the entire UPS, including its battery, is replaced.

A Pre-Failure Battery warning is given 30 days before a battery failure. The warning is indicated in one or both of the following ways:

• An LED showing the battery is low

• Notification from power protector software

Electrostatic discharge 110

Electrostatic discharge

Preventing electrostatic discharge To prevent damaging the system, be aware of the precautions you need to follow when setting up the system or handling parts. A discharge of static electricity from a finger or other conductor may damage system boards or other static-sensitive devices. This type of damage may reduce the life expectancy of the device.

To prevent electrostatic damage:

• Avoid hand contact by transporting and storing products in static-safe containers.

• Keep electrostatic-sensitive parts in their containers until they arrive at static-free workstations.

• Place parts on a grounded surface before removing them from their containers.

• Avoid touching pins, leads, or circuitry.

• Always be properly grounded when touching a static-sensitive component or assembly.

Grounding methods to prevent electrostatic discharge Several methods are used for grounding. Use one or more of the following methods when handling or installing electrostatic-sensitive parts:

• Use a wrist strap connected by a ground cord to a grounded workstation or computer chassis. Wrist straps are flexible straps with a minimum of 1 megohm –10 percent resistance in the ground cords. To provide proper ground, wear the strap snug against the skin.

• Use heel straps, toe straps, or boot straps at standing workstations. Wear the straps on both feet when standing on conductive floors or dissipating floor mats.

• Use conductive field service tools.

• Use a portable field service kit with a folding static-dissipating work mat.

If you do not have any of the suggested equipment for proper grounding, have an authorized reseller install the part.

For more information on static electricity or assistance with product installation, contact an authorized reseller.
