Procedure 6 - Connecting the ac male plug between the NT5C05CC rectifier

and the ac female plug in a 1200 A cabinet

 

Step

Action

 

1

Install the ac breaker ( 30 A / 3 phases per rectifier ) in the 380 /

 

 

415 volts ac service panel.

 

2

Put the ac breaker for the NT5C05CC rectifier, located in the ac

 

 

service panel, to OFF.

 

3

Run the metric no. 25 ( 10 AWG ) ac supply cable ( 3 conductors

 

 

and ground ) to the female receptacle ( see Figure 8 ). Connect the

 

 

female connector to the male connector.

 

4

Run the signal cable from the rectifier to the interconnect board or

 

 

controller as specified in the " Connecting the control signals "

 

 

section.

 

5

Secure the signal cables to the insulating busbar support, located in

 

 

the cabinet, with cable ties.

 

6

Start-up the rectifier as described in the “ Start-up “ section.
