4.7 Installing Protective Covers
Install the rear protective covers over the connectors at the rear of the fuse platform when all the
wiring connections are completed. To identify the covers, see
Figure 1 .
To install the plastic protective cover, thread the four 3/8-inch (9.53 mm) long, Phillips drive, 6-
32 pan-head screws into the standoffs located between the output power screw-down terminal
strips. Rotate each screw approximately two turns to get it started. Hold the cover so the
lettering is oriented properly and then install the cover over the screw heads. Slide the cover to
the left and then tighten the screws.
Caution: Do not apply power to the fuse platform until instructed to do so for testing (see
Section 6, Operation on page 28 ).
