Safety Precautions

To reduce the chance of accident, please read the safety precautions very carefully before

operation. The "Caution, Notice, Warning, Danger" in this manual do not represent all the

safety points to be observed, and are only used as supplement to various operation safety

points. Therefore, the installation and operation personnel must be strictly trained and

master the correct operations and all the safety points before actual operation. When

operating Emerson products, the safety rules in the industry, the general safety points and

special safety instructions specified in this manual must be strictly observed.

Electrical Safety I. Hazardous voltage

Some components of the power system carry hazardous voltage in operation; direct contact

or indirect contact through moist objects with these components will result in fatal injury.

Safety rules in the industry must be observed when installing the power system. The

installation personnel must be licensed to operate high voltage and AC power. In operation,

conductive objects such as watch, bracelet, bangle, ring, etc. are not allowed to be worn.

When water or moisture is found on the cabinet, turn off the power immediately. In moist

environment, precautions must be taken to keep moisture out of the power system.

"Prohibit" warning label must be attached to the switches and buttons which are not

permitted to be operated on during installation.

High voltage operation may cause fire and electric shock. The connection and wiring of AC Cables must be in compliance with the local rules and regulations. Only those who are licensed to operate high voltage and AC power can perform high voltage operations.

II. Tools

In high voltage and AC operation, special tools must be used. No common or self-carried

tools should be used.

III. Thunderstorm

Never operate on high voltage, AC, iron tower or mast on a day with thunderstorm. In

thunderstorms, a strong electromagnetic field will be generated in the air. Therefore the

equipment should be well earthed in time to avoid damage by lightning strikes.

IV. ESD

The static electricity generated by the human body will damage the static sensitive elements

on PCBs, such as large-scale ICs, etc. Before touching any plug-in board, PCB or IC chip,

ESD wrist strap must be worn to prevent body static from damaging the sensitive elements.

The other end of the ESD wrist strap must be well earthed.

V. Short-circuit

During operation, never short the positive and negative poles of the DC distribution unit of

the system or the non-earthing pole and the earth. The power system is constant voltage DC

power equipment; short circuit will result in equipment burning and endanger human safety.

Check carefully the polarity of the cable and connection terminal when performing DC live operations.

As the operation space in the DC distribution unit is very tight, please carefully select the operation space.

Never wear a watch, bracelet, bangle, ring, or other conductive objects during operation.

Insulated tools must be used.

In live operation, keep the arm muscle tense, so that when tool connection is loosened, the free journey of the human body and tool is reduced to a minimum.

Chapter 1 Introduction

NETSURE 702 IC4 Power system consists of R48-4000W rectifiers, Standard Controller Unit (M523S), AC distribution and DC distribution, which consist of distribution unit for load and battery. The Load distribution and Battery Distribution units can be designed as per users requirement. This system is used as a power supply for telecom equipment with system nominal voltage of -48V and positive terminal earthed.

1.1 Features

The power system is easy-to-operate/install/maintain. Its main features are: Rectifier uses APFC technology and therefore its power factor is up to 0.99

Wide AC input voltage range of 85~290V

Rectifier efficiency is >94% at the peak

Rectifiers compliant with UL, CE and NEBS standards

True hot pluggable, the replacement time is less than 1min

Perfect battery management with BLVD function

Up to 200 no of historical alarms

Provide RS232, Modem and dry contacts communication interfaces.

1.2 Operation Theory

The basic operating theory of power system is shown in the following figure:

Figure 1-1 Basic operation theory diagram

AC mains inputs rectifiers through AC input terminals and rectifiers breakers. (The rectifiers output to the priority load or to non-priority load through a LLVD, and output terminals of rectifiers connect with batteries). Batteries connect to the loads through BLVD contactor. The monitoring unit collects the working states of each part of the system and generates alarm to alert users.

1.3 Lightning Protection

Net sure 702 IC4 Power System has perfect lightning protection on input side, as shown in

the following figure:

Figure 1-2 AC lightning protection

A built-in II/C Surge Protection Devices (SPDs) is installed in the system, while each rectifier is designed with perfect lightning protection circuits. The whole system can withstand 8/20s surge current 20kA for 5 times, or 8/20s surge current 40kA once. To further protect the system, Class I/B SPD which comes as optional item (with through current capacity of at least 50kA) can be installed close to the main AC distribution board.

1.4 LLVD and BLVD

Batteries will start discharging to power loads once the AC mains fails. When the battery voltage reaches to 45V (low voltage point, adjustable), the system will raise audible/visual alarms. When the battery voltage continues dropping to 44.0V (LLVD point, adjustable), the LLVD contactor will act to cut off power supply to non-priority loads (such as local exchange) so as to ensure power supply to priority loads (such as transmission equipment). As the discharge goes on, when the battery voltage drops to 43.2V (BLVD point, adjustable), the BLVD contactor will act to cut off the connection between the batteries and the system, stopping the power output and protecting the batteries. When AC mains recover, rectifiers will resume outputs, LLVD & BLVD contactors will close automatically, and the system will restore to normal operation.

1.5 Alarm and Protection

Based on the real-time data collected by the monitoring module, the system can detect the states of output breakers, battery breakers and class II/C SPD. User can set the severity level of faults such as AC input over/under-voltage, DC output over/under-voltage, etc. so as to raise audible/visual alarms upon designated faults. User can also set alarm types of alarm dry contacts.

3.1.2 Main Functions and Features

1. Hot Swappable The rectifier is designed to be plug-and-play. There will be no arcing and the terminals will not be damaged when inserting/removing the rectifier from a live DC power system. A rectifier can be replaced in less than 1 minute and the inrush current will be no larger than 150% of the rated input steady-state peak value. When the rectifier is plugged into the system, the system output voltage will not be affected.

2. Active Load Sharing The rectifier uses advanced digital active load sharing technology that maintains balancing to within 2A.

3. Output Characteristics The relationship between output voltage and current is summarized in below table and depicted graphically in Figure 1-6. Output Power Output Current Output Voltage 4000 W 69 A 58Vdc 4000 W 83.34A 48Vdc

Figure 1-6: Output Characteristics

4. Current Limit Function The rectifier has current limit function. The current limit point can be set between the ranges of 6 to 72.9A. The setting is done using the SCU. The current limit accuracy is 2A when the output voltage ranges from 42 to 58.5 V, and 3A for output voltages ranges from 30 to 42 V, 5A for output voltages below 30V.

5. Adjustable Output Voltage The output voltage can be set through the SCU within the range of 42 V to 58V. The accuracy is 0.1V.

6. Fan Control When the input voltage is within a normal range, the built-in processor adjusts the fans speed according to the rectifiers internal temperature and Load. For example, a higher temperature and load will increase the fan speed. Above 45C with full load, the fan will be operating at full speed. When the input voltage is abnormal, such as very low or high input voltage, the fan will turn off.

18


7. Input Over/Under Voltage Protection The rectifier will shut down and its protection indicator (yellow) will light up when the input voltage is lower than 85Vac or higher than 300Vac. This condition will be reported to the SCU and the SCU will process the alarms accordingly.

8. Output over Voltage Protection (HVSD) There are two kinds of HVSD: a. The fixed hardware HVSD is 59.5V (within the range of 59 to 60V), In case of hardware HVSD; the rectifier has to be restarted manually. b. The software HVSD is settable; its level (from controller) is from 56V to 59V. The rectifier will shut down when its output voltage is higher than HVSD set point. Note that the HVSD set point can be modified through the SCU and the permissible range is from 56 V to 59 V. The occurrence of a HVSD condition will cause the rectifiers alarm indicator (red) to light up. The failure information will be reported to the SCU and the SCU will process the failure accordingly. Note also that the rectifier can only be restarted manually should a HVSD condition occur twice within a 5-minute interval. The rectifier also has two additional software settings that can be configured using the SCU: Manual restart and Automatic restart attempt should be within 5 seconds of a HVSD condition.

9. High Temperature Protection The rectifier will shut down and its protection indicator (yellow) will light up when its internal temperature becomes higher than 90C. The causes for the high temperature condition may be that the ventilation openings are obstructed, the ambient temperature is too high, or the rectifier fan has failed. The failure information will be reported to the CSU and the CSU will process the failure accordingly. The high temperature alarm will clear and the rectifier restored to normal operation when its internal temperature returns to normal values (hysteresis is between 5 to10C).

10. Communication Failure The rectifiers protection indicator (yellow) will flash should it experience a communication failure. The failure information will be reported to the SCU and the SCU will process the failure accordingly. During a communication failure, in order to protect the battery, the rectifier output voltage will automatically adjust to 53.5 V (this is a default value which can be modified using the SCU). The rectifier will revert to normal operation once normal communication is restored.

11. Fan Fault Protection An alarm will be generated upon a fan fault. In such cases, the fault indicator (red) on the rectifier front panel will flash and the rectifier will also inhibit its output. Auto-recovery is enabled upon the clearing of the corresponding fault.

12. Unbalance of Rectifier Output Current When the output current of the rectifiers in a DC power system is unbalanced, the rectifier whose output current is unbalanced will be identified automatically and its protection indicator (yellow) will light up. The failure information will be reported to the SCU and the SCU will process the failure accordingly.

Chapter 5 Testing Procedure

Long-distance transportation may cause damage to the cabinet, rectifiers and monitoring module, furthermore, assembly and connection errors may occur during the assembling of the power supply system. Therefore, to avoid accidents, testing must be conducted strictly in accordance with the testing procedures after the system is assembled instead of hastily putting the system into operation.

Close attention should be paid to the following safety points during testing.

Before switching on the system, check if the connections and screws inside the cabinet are loose.

The technical contents contained in testing are extensive; therefore the testing engineer must have had relevant technical training.

The testing involves working with live wires. Please stand on a dry and insulated object during operation. Do not wear watch, necklace or any other metal things. Use insulated tools during testing.

Avoid touching two live objects with different potentials.

During testing, do check if the conditions of the relevant parts are normal before the switch-on operation.

During operation, if operation by other people is not permitted, a prohibition sign "No switch-on, in operation" should be hung on the distribution equipment.

Close observation is required during the testing. The system should be turned off immediately if any malfunction occurs. The cause of the malfunction must be found out before resuming the testing.

NetSureTM 702IC4

5.2 Resetting System

To prevent improper transportation or installation error from damaging the system, before powering on the system and putting it in operation, first you must disconnect some branches of the system, and connect them one by one during testing.

1. Switch off all of the distribution switches of the AC/DC distribution units.

2. Make sure that the battery fuse or the shorting stub of the battery is disconnected.

3. Make sure that the load MCB is pulled switched off.

5.3 Testing AC Distribution

1. Turn on the AC distribution switch in the power room to feed the mains supply to the power supply system; then measure the L-N voltage of the three phases with a multi-meter to confirm the mains condition. If everything is normal, proceed with the next step.

2. Turn on the corresponding AC input MCB.

5.4 Testing Rectifier

1. Turn on one rectifier input MCB in the AC distribution unit to feed AC supply to the corresponding rectifier, the rectifier should operate normally.

2. Turn off this MCB, and turn on the other rectifier input MCBs one by one to check if all the other rectifiers operate normally.

If all of the rectifiers can operate normally, switch them on. In case of rectifier malfunction, take the rectifier out and inspect it.

5.5 Testing Monitoring Module

When the rectifiers are operating normally, switch on the monitoring module, the monitoring module should start and display the start screen. If the system self-test is normal, seconds later, the following main screen will appear.

There are default system parameter settings in the monitoring module, including the AC voltage alarm points, DC voltage alarm points, battery management parameters, which are available on the parameter card delivered with the system. If the battery capacity or charging parameters set by user are different from those on the parameter card, or if user has different BLVD and LLVD management requirements, please reset the system parameters according to the actual situation, and record the new settings on the parameter card.

5.6 Testing Distribution Switches

1. close/disconnect the AC input MCBs, the rectifiers should operate normally.

2. Respectively operate the buzzer switch.

3. Close the AC output MCB for user equipment; mains supply should be fed to the corresponding user equipment.



5.7 Battery Connection

A. Before turning on the battery switch, confirm with a multi-meter that the battery is not connected with reverse polarity. B. When connecting the battery, be careful not to short the two battery terminals. C. When connecting two batteries, be careful to avoid battery mutual charging due to unequal terminal voltages of the two batteries.

1. Turn on one rectifier, and set the rectifier float voltage to a value with less than 0.5 V difference from the battery voltage through the monitoring module

2. Close the battery fuse or the shorting strip of the battery that are disconnected during installation to connect the battery branch to the power supply system, the BLVD contactor should be able to close normally to parallel connect the battery to the rectifier output;

3. Readjust the rectifier float voltage to the standard value 52V through the monitoring module (at this time, the rectifier charges the battery, and may enter current limiting state, so the actual output voltage cannot reach the standard value, note that adjustment should be done after all rectifiers are started)

4. Switch on all of the rectifiers one by one

5. Measure the system DC output voltage with multi-meter to check if it is normal or check if the system works normally through the monitoring module.

5.8 Load Connection

Before connecting load to the system, check with a multi-meter if the connection polarity of the load and the power system is correct and the voltage is normal.

1. Close the load MCB, or insert the load fuse with special handle, DC power should be fed to the load;

2. Adjust the system parameters through the monitoring module, and make sure that the information viewing and output control functions are normal.

Chapter 7 Installation Preparation

This chapter introduces installation requirements, storage conditions, installation preparation and unpacking inspection.

7.1 Installation Requirements

Environmental Requirements: The environmental conditions listed in Table 5-1 must be met

when locating the equipment.

Table 5-1 (Environmental conditions for the equipment room)

Environmental conditions Recommended range

Ambient temperature -10C j; to 55C (de-rating from 40C)

Humidity 90%RH, no condensation

Dust density 1mg/m3

Sunlight No direct sunlight

Corrosive materials No pollutants, such as salt, corrosive materials, and

smoke

Vibration 1.5m/s

Harmful organisms None

Mould None

Dampness The shelter should be waterproof

The equipment may be prematurely damaged if dust or sand accumulates in it. The following

measures are recommended for dirty environment:

1. The equipment should be installed in an airtight and air-conditioned room. The air

conditioner filter should be adequately maintained without being obstructed. To reduce the

dust in the equipment room, unattended equipment room is recommended.

2. Clean the air filter periodically to provide clean air.

7.2 Layout Requirements Of The Equipment Room

Antistatic As for antistatic requirement, the absolute value of the static voltage of the equipment, wall

and people to the ground should be less than 200V. Raised floor or antistatic ceramic tile is

highly recommended for the equipment room. The antistatic earth resistance should be no

greater than 10. Care should be taken regarding antistatic during equipment unpacking,

transportation and operation.

Weight capacity and shockproof



When installing the power system in areas subject to frequent earthquakes, shockproof

measures should be taken. Firstly, expansive bolts should be used to fix the system;

secondly, the system should be reinforced as shown in Figure 1-20 to enhance its

shockproof ability. Because the power supply system is relatively heavy, the weight capacity

of the equipment room should meet relative requirements and is determined based on the

equipment configuration.

Figure 1-20 Rein forcing the cabinet for shockproof purpose

Fire protection facility The equipment room should comply with relevant fire protection regulations and

requirements for power distribution, and provide adequate fire protection facility, such as

dry-chemical extinguisher and automatically explosive fire protection ball.

7.3 Power Supply

General Mains power should be used as the main AC source; backup batteries and generator should

be provided according to the actual power source conditions. AC source composed of mains

power and user-provided generator should use centralized power supply mode to supply

power, and low voltage AC power supply system should use three-phase five-line (the

neutral line is invalid) mode.

The AC power cables should be copper core cable and sized to suit for the load. It is

recommended that the power cables outside the equipment room should be buried directly

under the ground or by means of cable pipe. Power cables should be laid separately from

signal cables.


NetSureTM 702IC4

7.4 Safety Protection

Lightning protection & surge protection The lightning protection and earthing system of telecom stations should comply with relevant

standards.

The power supply system has Class-C SPD. The preceding AC input equipment should be

equipped with a Class-B SPD. To achieve better surge protection, it is recommended to

mount Class-B SPD before the AC mains is connected to the system. The mounting of

Class-B SPD is shown in Fig 1-20.

Class-B should be purchased and mounted by the user. If condition permits, it is

recommended that the cable length between the Class-B SPD and the AC distribution unit of

the power supply system range between 5 ~ 10m. And this section of cable should be routed

indoors to avoid direct lightning strike. When mounting the Class-B SPD, attention should be

paid to the sectional area and length of the cable connecting the Class-B SPD: the sectional

area should be no less than 25mm2, the cable should be as short as possible, and so is the

earth cable of the Class-B SPD. The SPDs should be inspected periodically to ensure their

normal operation.
