Drop Cable Termination at the PSU (Type 4A only)

1. Run cable end into the PSU. Estimate the length of end required for termination of

wires (allow 150mm of conductor for a maintenance re-termination of wires) and

cut cable to length.

2. Strip outer cable sheath using a knife or cable stripping tool to expose 150mm of

conductor, leaving sufficient length to allow the cable retaining clip to grip the

sheath.

3. At the PSU terminate the wires of the drop cable with the red insulated terminal

pins and screw to the terminal blocks(TB1 & TB2). Table 12 illustrates the

connections of the drop cable to the connector blocks inside the AC PSU.
