DRd Right I/O Data Terminations
Auxiliary Power
The auxiliary power connector (labeled Aux Power) provides termination for up to 16 wires
in the eight position pluggable connector. Each terminal allows up to two 16 AWG (1.5mm
2
)
wires and provides 24vDC power to control stations when used with the Paradigm Station
Power Module. Auxiliary power is not compatible with the Echo or SmartLink Station Power
Module.
Step 1:
Pull control auxiliary power wiring (typically 16 AWG (1.5mm
2
) red / black wire
pair) into the 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
connector and tighten the screw to secure the wire into the connector.
Step 7:
Repeat steps 5 and 6 for each auxiliary power wire pair.
Step 8:
Replace the connector on the right I/O board.
N o t e :
A DRd enclosure supports the use of either the Unison RideThru option or the
Unison BatteryPack option, but not both.
W A R N I N G :
RISK OF DEATH BY ELECTRIC SHOCK! Failure to disconnect all power to
the enclosure before working inside the DRd could result in serious injury
or death.
De-energize main feed to DRd enclosure and follow appropriate Lockout/
Tagout procedures as described in NFPA Standard 70E. It is important to
note that electrical equipment such as dimmer enclosures can present an
arc flash safety hazard if improperly serviced. This is due to available large
short circuit currents on the feeders of the equipment. Any work on
energized equipment must comply with OSHA Electrical Safe Working
Practices.
N o t e :
All low voltage control cables must run in separate conduit from power wires.
N o t e :
It is required that you terminate LinkConnect / EchoConnect station wiring and the
auxiliary power wiring in the same enclosure (rack 1) where the station power
module and architectural control processor will be installed.
