NT5C05C Installation and User Manual
Procedure 8 - Connecting an NT5C05CC rectifier directly to a controller
Step Action
1
If an NT6C43PB interconnect board is not available, each rectifier
must be connected directly to the controller with the following
cables :
•
P0723784, P0723785 or P0723786 ( for conventional
controllers )
•
P0723708, P0723709 or P0723210 ( for front access
controllers )
end
For controllers not manufactured by Emerson Energy Systems see Table
12 in the " Functional Description " chapter describing the pin assignments
of the rectifier. Refer to Table 8 for the pin assignments of connectors J7
to J12 on board NT6C43PB.
Note:
The alarm and control signals in Table 8 are all ground
signals except for the RC– signal that is a –48 V
battery signal.

3.7.1. Monitoring of the shunt current
A 12-pin connector ( J13 ) is also available on the NT6C43PB
interconnect board for monitoring the individual output current shunt
readings ( 250 A / 50 mV for example ) of each rectifier in a cabinet or a
frame ( see Table 9 ).
