8. Install heat-shrink tubing insulation around the power cables.
To install heat-shrink tubing:
a. Slide the tubing over the portion of the cable where it is attached to the lug barrel. Ensure that
tubing covers the end of the wire and the barrel of the lug attached to it.
b. Shrink the tubing with a heat gun. Ensure that you heat all sides of the tubing evenly so that it
shrinks around the cable tightly.

NOTE: Do not overheat the tubing.

terminal (see Figure 135 on page
The terminal studs for each PSM are numbered on the faceplate. For example, the DC input
terminals for PSM0 are PSM0_1 and PSM0_2, in the first and second rows of the terminal blocks.
There are sixteen 60-A input terminals for the eight PSMs supported for each PDU.
