40A Service Bypass Unit: Specifications and Procedures

Connecting the Communications Cable to the V-Class System

Connecting the Communications Cable to the V-Class
System
1. Use the instructions that came with the component interface multiplexer (PCI Mux)
card to install the card into the SPU.
2. Attach the RS-232 cable to the UPS Port connector on the rear panel of the Service
Bypass Unit. Secure the cable to the connector by tightening the small mounting screws
on each side of the connector with a small blade screw driver.
3. Attach the other end of the RS-232 cable to a RS-232 connector on the Mux port module.
Refer to Figure E-3.

Connecting the Test Station

It is recommended that the test station for the V-Class SPU be connected to another UPS.
It is further recommended that the communications cable for the test station UPS not be
connected to the Mux port module but rather directly to the test station. Figure E-3 shows
how to connect the test station power and communications cables.
