INSTALLATION
5 VDC Power Supply Connection
The 5 VDC Power Supply is supplied as either 115 or
230 ±10% volts AC at 50/60 Hz frequencies. Maxi-
mum output of the power supply is 300 mA at
5 volts DC.
A properly color-coded wire must be obtained locally
to conform to local, state and country regulations for
connection of the 115/230 VAC line voltage. Two
leads, red and black, are attached to the power supply
to connect to the Universal LINC.
DANGER: Disconnect any line
voltage power supply at the source
before attaching wiring to prevent
possible electrocution.
The line voltage power supply should be wired to a
non-switched fused spur to prevent the power from
being turned OFF accidentally. A fuse or breaker
rated at 5 amps (115 VAC input) or 3 amps (230 VAC
input) should protect the controller from overload.
The 5 VDC Power Supply requires a 3-conductor,
power cable for the line voltage power supply, similar
to the one used by most computers. It may use a
typical plug in connector or have bare wire at the
other end (for connection to a circuit breaker box). It
is recommended that the line voltage supply cable be
installed within suitable conduit if it is run outside
the enclosure. Ensure that all wiring meets local, state
and country codes, as well as follows NEC recom-
mendations.
To install the Power Supply Module:
DANGER: Always disconnect the
power before working inside or
around an electrical enclosure.
1. Mount the 5 VDC Power Supply using either
the DIN rail or panel mounting method.
2. Attach the black power lead from the 5 VDC
Power Supply to the GND terminal and the red
power lead to the 5 VDC terminal of the LAN
port.
3. Install conduit, if necessary to meet code,
between the device and an appropriate line
voltage power supply at a circuit breaker or
fuse box.
4. Install a 5 amp (115 volt line voltage) or 3 amp
(230 volt line voltage) fuse or circuit breaker in
the line voltage spur. Be sure to place a label on
the circuit breaker indicating the Universal
LINC power shut-off point.
5. Plug the line voltage cable into the receptacle
on the 5 VDC Power Supply. The plug is keyed
for correct orientation.
6. Connect the line voltage cable into a standard
receptacle or attach each conductor to the fuse
or circuit breaker according to regulations.
