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 :

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 ).
