Emerson 200I/48-NT5C05C Monitoring of the shunt current, Pin assignment for connectors J7 to J12

Installation 29

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.

2	RG+	Remote sense	Input
3	RC–	Remote sense	Input
4	FAN ALM	Fan fail alarm	Output
5	HVSDR	High voltage shutdown reset	Input
6	HVSD	High voltage shutdown	Input
7	RFA	Rectifier failure alarm	Output
8	TR	Temporary release	Input

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 ).
