Wiring flow
All cabinets have been designed to provide a clear layout and
logical progression for all power circuits.
The main supply conductors enter at the top panel. Input power
is then fed to the modules inside the cabinet.
Field wiring for branch circuits that are connected to the
SCMA modules also enter from the top of the cabinet. Ground
connections are provided at the top of the cabinet for landing
grounding conductors.
Note: Check the stated voltage rating of the controller before
connecting to the supply and check that it matches the supply
voltage. All cabinets are 120-277V universal input

Connecting the supply
The suggested entry point for the supply wiring is via the right
most knockout on the top panel of the chassis. This provides
immediate access to the circuit breaker that supplies the
modules with power. Use a suitable conduit and coupler to feed
the source wiring safely into the chassis.
See the diagram below for connection details. The main earth
terminal is located near to the neutral lug. The earth connection
is bonded to the main backplane of the chassis and the outer
panels.
Please consult the image below for details about the maximum
permissible supply wire gauges for the various controller
models.
Connecting 120V-277V AC dimmer loads
The AC dimmer modules (SCMA0401-NA) will be pre-mounted
on interior DIN rail per the order specifications.
Prior to dimmer connection, test the load directly connected to
the branch circuit breaker to verify there are no shorts. Remove
all wire cuttings form the enclosure.
4 dimmer channels are provided on each SCMA0401-NA
module. Channels 1+2 and 3+4 may be combined to provide
larger load control. WaveLinx Wired programming software
can be programmed to meet control configuration and
requirements.
Prior to dimmer connection, test each load to verify there are no
shorts. Remove all wire cuttings from the enclosure.
