Installing Power Cables
There are two cable routes as follows:
n The IFU Alpha power cable runs from the IFU mounting location to
the surge suppression assembly.
n The IFU Beta power cable runs from the IFU mounting location to
the surge suppression assembly.
To install the IFU power cables:
1 Route the IFU power cables to a surge suppression assembly according to
the site drawing.
NOTE: Allow an extra three-foot service loop at the IFU and
twelve inches at each surge suppressor. Use large radius
bends to avoid kinking the cables during the cable routing.
NOTE: Connect the cable shields to the suppressor
mounting panel. Trim the shield back to the cable breakout
and keep the shield as short as possible.
2 Trim each cable to the appropriate length.
3 Strip each cable wire to 3/8 inch and tin.
4 Attach the IFU power cables to the surge suppressors as shown on
Figure 3-3, Figure 3-4, and Table 3-3.
