Procedure 8 - Connecting an NT5C05CC rectifier directly to a controller

Step

Action

1If 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 ).
