Flexible Conduit Replacement • Installation Guide

This guide provides instructions for replacing the power cord of an Extron Cable Cubby or Hideaway Surface Access (HSA) enclosure with conduit (not provided) where required by local codes.

UL Guidelines

The Underwriters Laboratories (UL) guidelines listed below pertain to the installation of flexible conduit into an Extron Cable Cubby or HSA.

WARNING: Installation and service must be performed by a qualified electrician only.

• This unit is not to be used beyond its rated voltage range.

• This unit must be wired to a UL-listed distribution box. The installer is responsible for obtaining and installing the box.

• This unit must be installed in accordance with the National Electrical Code and with all local codes.

Removing the Old Cable

WARNING: Ensure power is removed from the Cable Cubby or HSA by disconnecting the power cable from the electrical outlet.

1. If the power module is installed in a Cable Cubby, remove the power module. If a clamshell is installed on the base of the HSA, remove the clamshell.

NOTE: If necessary, remove the Cable Cubby or HSA from the table in which it is installed.

2. Unplug any devices plugged into the sockets of the power module or HSA.

5. Remove the sealing nut.

6. Remove and retain the two screws on the power input plate on the bottom of the power module or HSA. Gently pull out the plate and remove it from the cut portion of the cable, leaving the wiring attached to the power module.

NOTE: If necessary, push the cable through the cord grip so that it is not pulled by the plate.

7. Remove the lock nut and cord grip from the power input plate.

3. For the Cable Cubby power module, remove and retain the four screws on the side and remove the side plate (see image at right).

4. Cut the power cable at approximately 0.5 inch below the sealing nut on the power module or HSA.

2. Take the replacement wires and twist together the two supply (white) wires (one from the power module or HSA and one from the conduit assembly), the two return (black) wires, and the two ground (green) wires. Twist a wire nut (not provided) onto each twisted pair.

3. Place the power input plate assembly on the base of the power module or HSA, gently tucking the power cables and wire nuts into the enclosure. Use tie wraps if necessary.

NOTE: If necessary, reorient the conduit nut and wires for the best fit.

ATTENTION: If inserting the replacement wires into an HSA enclosure, be careful not to damage the wires when closing the lid of the HSA. Close the lid carefully and make sure that it does not contact the wires inside the enclosure.

4. Secure the power input plate, using the screws.

6. Remove power from the AC distribution (junction) box.

WARNING: Ensure power is removed from the UL-listed AC distribution box before connecting the power wires and conduit. Hazardous voltages are present in the AC distribution box.

NOTE: Ensure the AC distribution box is rated for and equipped with a 15-amp circuit breaker.

7. Wire the free end of the AC power wires and conduit into the AC distribution box.

Installing the Replacement Wires

1. Cut and strip the green, black, and white wires in the power module or HSA at the necessary length.

NOTE: The length of the stripped wires should allow for connection with the replacement wires (see step 2) and for fitting into the power module or HSA enclosure (see step 3).

Assembling the Flexible Conduit and Power Input Plate

1. Insert the threaded conduit fitting into the power input plate (see image at right for dimensions). The power input plate contains a 1/2 inch trade size knockout.

NOTE: Make sure the length of the conduit and wires extends from the power module or HSA location to the AC distribution box.

WARNING: Ensure power is removed from the UL-listed AC distribution box.

2. Fasten a conduit nut (not provided) on the threaded conduit fitting.

3. Insert replacement wires through the conduit. Pull the wires out of the conduit assembly to the length of approximately 3 inches.
