4.
Guide a two-conductor, shielded cable, or two wires in conduit through the top
conduit hub of the amplifier junction box.
WARNING: To maintain the explosion proof classification of the junction box
connection, a conduit seal must be used within 18 inches of the amplifier
junction box conduit hub used for wiring to the controller.
5.
Pull out the controller terminal strip and connect the two wires to the terminal strip as
follows (see Figure 7).
•
Connect the positive wire to the terminal labeled SIG/PWR “+” terminal.
•
Connect the signal wire to the terminal labeled SIG/PWR “S” terminal.
CAUTION:
If shielded cable is used, leave the cable shield’s drain wire disconnected and
insulated at the amplifier junction box. You will connect the opposite end of the
cable’s drain wire to the controller’s chassis (earth) ground.
6.
Reinstall the controller terminal strip into its socket.
7.
Secure the amplifier junction box’s cover to the junction box.
8.
Route the cable or wires leading from the amplifier junction box through one of the
conduit hubs at the controller housing.
WARNING: To maintain the explosion proof classification of the junction box
connection, a conduit seal must be used within 18 inches of the controller
conduit hub used for wiring to the amplifier junction box.
CAUTION:
Do not route power and transmitter wiring through the same controller conduit hub.
The power cable may disrupt the transmission of the transmitter signal to the
controller.
