Important Safety Instructions
Danger! Adhere to the “Important Safety Instructions”
presented at the front of this document.
Warning! Observe proper polarity when making output
connections.
Recommended Torques
300 in-lbs for 3/8-inch hardware (when using standard
flat and lock washer).
180 in-lbs for 3/8-inch hardware (when using a Belleville
lock washer).
General
DC output leads are connected to the output busbars located on
the back of the rectifier shelves. These busbars provide 3/8”
clearance holes for installation of customer-provided two hole lugs
that have 1 inch centers and 3/8 inch bolt clearance holes.
Customer must order or provide lug mounting hardware.
You connect DC output leads per a single rectifier shelf in the
system or for pairs of rectifier shelves in the system (depending on
how many shelves are in the system). Refer to Figure 14.
DC output cables can either enter from the right, from the left, or
from the rear. The shelf should have been configured for your
installation site per the “Changing the Direction of the DC Output
Cables” procedure on page 3. Refer to Figure 15 for typical lug
layout diagrams.
After making DC output connections, re-install any rear shield
removed in “Mounting the Rectifier Module Mounting Shelf(s) to a
Relay Rack” on page 3.
