Connecting the Supply
The suggested entry point for the supply wiring is via
the rightmost 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 Relay Loads
The relay modules (SCMR1220-NA) will be pre-mounted
on the interior DIN rail per the order specifications. Unless
otherwise specified, latching relays (single pole) will be
provided for connection to lighting loads.
Prior to relay connection, test the load directly connected to
the branch circuit breaker to verify that there are no shorts.
Remove all wire cuttings from the enclosure.
Relays are numbered 1-12 on each SCMR1220-NA module.
Using the iLumin Plus programming software each relay can
be programmed to meet control requirements. The table
below indicates the minimum wires size to be used with
various load currents.

Connecting 0-10V Dimmer Loads
Temperature 32° F to 104° F (0° C to +40° C)
Humidity 0 to 95% non-condensing
The dimmer modules (SCMH1200-NA) will be pre-mounted
on the interior DIN rail per the order specifications. Each
0-10V dimmer requires a corresponding relay from the
SCMR1220-NA to turn the lighting load ON/OFF. This
mapping is performed during programming.
Prior to dimmer connection, test each load to verify there
are no shorts and 0-10V polarity is correct. Remove all wire
cuttings from the enclosure.
0-10V dimmers are number 1-12 on each SCMH1200-NA
module. Each 0-10V dimmer can be programmed to be
either source or sink the 10VDC, by default the dimmers are
sink type.
