PS 123, cont’d

WInstallation and service must be performed by a qualified electrician only.

CA UL listed electrical distribution box is recommended for the termination of the conduit opposite the PS 123 power supply. See "UL requirements," below.

UL requirements

The Underwriters Laboratories (UL) requirements listed below pertain to the installation of the flexible conduit onto a PS 123 power supply.

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

•This unit must be wired to a UL listed distribution box.

NThe UL approved electrical distribution box is not included with either the PS 123 power supply or the Flexible Conduit Adapter Kit; 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.

Installing the flexible conduit cable

Install the flexible conduit cable assembly to the PS 123 as follows:

1.

Unplug the IEC power cord.

2.

Remove and retain the two Phillips head screws that

 

secure the EMT plate (figure 3, below) to the PS 123 rear

 

panel.

4. Carefully lift the top cover up, taking care not to remove it completely.

CRough handling of the top cover can tear the wiring that connects the front panel LED.

5.

Use the Phillips head end of an Extron Tweeker or a small

 

standard screwdriver to loosen the screws holding the hot

 

and neutral wires on the side of the terminal block nearest

 

the EMT plate opening (figure 5).
