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
DC output cables can either enter from the right, from the left, or from the rear. The shelf should have been

After making DC output connections, re-install any rear shield removed in “Mounting the Rectifier Module
