Step 2:

Strip 3/16” (5mm) if insulation from the ends of each wire pair.

Step 3:

Remove the LinkPower connector (labeled LON) from the right I/O board.

Step 4:

Loosen the terminal screws for as many wire pairs you are terminating.

Step 5:

Insert each white wire from the pairs into an “A” terminal on the connector and

tighten the screw firmly to secure the wire into the connector.

Step 6:

Insert each black wire from the pairs into an “B” terminal on the connector and

tighten the screw firmly to secure the wire into the connector.

Step 7:

The 14 AWG (2.5mm

) ground wire can terminate to the ground bus located

inside the ERn enclosure.

• If grounded metal conduit is installed a ground wire may not be required for

termination. Reference the related

station installation manual

for details.

Step 8:

Replace the connector to the right I/O board.

Terminate Auxiliary Power

The auxiliary power connector (labeled Aux Power) provides termination for up to 20 wires

in the ten position pluggable connector. Each terminal allows up to two 16 AWG(1.5mm

)

wire and provides 24 Vdc power to Unison control stations when used with the Paradigm

ACP.

Step 1:

Pull auxiliary control power wiring (typically 16 AWG (1.5mm

) red / black wire

pair) into the ERn enclosure through the conduit opening previously prepared.

Step 2:

Strip 3/16” (5mm) of insulation from the ends of each wire pair.

Step 3:

Remove the auxiliary power connector from the right I/O board.

Step 4:

Loosen the terminal screws for as many auxiliary wire pairs as you are

terminating.

Step 5:

Insert the black auxiliary power wire from the pair into a “-” terminal on the

connector and tighten the screw to secure the wire into the connector.

Step 6:

Insert the red auxiliary power wire from the pair into a “+” terminal on the

connectors and tighten the screw to secure the wire into the connector.

Step 7:

Repeat steps 5 and 6 for all auxiliary power wires in the rack.

Step 8:

Replace the connector on the right I/O board.

N o t e :

It is required that you terminate LinkPower station wiring and the auxiliary power

wiring to the ERn enclosure I/O board that will host the Paradigm Station Power

Module (P-SPM).
