Appendix B: NT7D10 PDU connections
3 Connect the red BAT (–48 V) wires:
• At the power plant:
For an MFA150 or NT6D82, connect two wires to the first two
circuit breakers in the main control/distribution panel (see
Figure 161 for MFA150, Figure 162 for NT6D82).
For a QBL12 or QCA13, connect two wires to the first two
available 30-amp fuse output connections on the –48 V terminal
panel (see Figure 163).
Note: Each 30-amp fuse output has two connection points on the
distribution panel. Only one 30-amp connection point is required for
every two modules; typically, #6 AWG is adequate (#4 AWG can be
used).
For a QBL15, connect the wires to terminals 1, 2, or 3
(DISCHARGE) on TB1 (see Figure 164).
• At the pedestal, connect the wires to the terminal block:
For modules 0 and 1, connect to BAT 0 and add a strap (if not
already installed) between BAT 0 and BAT 1.
For modules 2 and 3, connect to BAT 2 and add a strap (if not
already installed) between BAT 2 and BAT 3.
4 Connect the black BATRTN (48 V return) wires:
• At the power plant:
For an MFA150 or NT6D82, connect two wires to the ground
bus/LRE.
For a QBL12 or QCA13, connect two wires to the LRE.
For a QBL15, connect two wires to the positive bus.
• At the pedestal, connect the wires to the terminal block:
For modules 0 and 1, connect to RTN 0 and add a strap (if not
already installed) between RTN 0 and RTN 1.
For modules 2 and 3, connect to RTN 2 and add a strap (if not
already installed) between RTN 2 and RTN 3.
