AC Input and AC Input Equipment Grounding Connections
DANGER!
Adhere to the “Important Safety Instructions” presented at the front of this document.
Connections to Factory Installed Module Mounting Shelves
The system provides either a separate AC input connection for each rectifier position or a separate AC input
connection for every two (2) rectifier positions in the factory installed module mounting shelves. Circular
openings are provided in the top of the AC input wireway panels for AC input and AC input grounding
conductors. The openings accept 3/4 inch conduit fittings. It is recommended that AC input wiring be
provided to all rectifier mounting positions, including currently unused positions. This wiring will ease future
installation of rectifiers to meet increased load requirements.
NOTE!
A grounding conductor must be provided with each conduit.
Procedure
Refer to Figure 25 as these procedures are performed.
Accessing Connections and Routing Wire
1. Remove the two AC input connector covers and the AC input wireway covers by first loosening the
fasteners that secure each of them.
2. Install conduit fittings as required in the top of the AC input wireways. Plug buttons are provided, and
must be installed in the openings not being used.
3. Route wiring into the AC input wireways through the previously installed conduit fittings.
Making AC Input Connections
NOTE!
Module mounting positions are lettered left to right as viewed from the front of the shelf, A-D in
the top row and E-H in the bottom row of each shelf sub-assembly.
NOTE!
If module mounting positions B, C, F, and G are intended solely for DC-DC Converter installation
(Converter Option must be installed), AC input connections to these positions are not required.
1. Make AC input connections as shown in
Figure 25
. Connect each wire by inserting the stripped end
into the wire opening, and then tightening the screw. Recommended torque is 10 in-lbs for the
individual PCU feed terminal blocks and 18 in-lbs for the dual PCU feed terminal blocks.
