Section 4: System Control & Electronics

ATEX System Connections

Required field connections to place the NJEX into

operation are as follows:

1. Connect your I.S. Power Supply to the yellow

cable connection coming from the bottom of the

N-300 controller, and exiting the rear of your

system enclosure,

refer to the Wiring Control

Document on page 117 in Appendix D

2. Connect the flow signal device to the termination

block located in the system control enclosure,

figure 6,

refer to the Wiring Control Document on

page 117 in Appendix D

2a. If used, connect the optional Inhibit Input signal to

the termination block located in the system control

enclosure, figure 6,

refer to the Wiring Control

Document on page 117 in Appendix D

2b. If used, connect the RS-485 communication

wiring as required to the termination block located

in the system control enclosure, figure 6,

refer

to the Wiring Control Document on page 117 in

Appendix D
