2. Mark the mounting hole locations on the wall
using the dimensions in one of the mount
positions shown in Figure 2. Or hold the
controller up to the wall or surface in a proper
mount position and mark the hole locations
through the mounting clips.
3. Drill holes in the wall or surface at the marked
locations, and insert appropriate wall anchors in
the holes (if necessary).
4. Hold the controller in place, and insert the
screws through the mounting clips and into the
holes (or anchors). Carefully tighten all of the
screws.
Important:
Do not over-tighten the mounting
screws. Over-tightening the screws may
damage the mounting clips.
Wiring
Observe the following guidelines when wiring a CGM
controller:
CAUTION
Risk of Electric Shock:
Disconnect the power supply before making electrical
connections to avoid electric shock.
ATTENTION
Mise En Garde: Risque de décharge électrique:
Débrancher l'alimentation avant de réaliser tout rac-
cordement électrique afin d'éviter tout risque de
décharge électrique.
CAUTION
Risk of Property Damage:
Do not apply power to the system before checking all
wiring connections. Short circuited or improperly con-
nected wires may result in permanent damage to the
equipment.
ATTENTION
Mise En Garde: Risque de dégâts matériels:
Ne pas mettre le système sous tension avant d'avoir
vérifié tous les raccords de câblage. Des fils for-
mant un court-circuit ou connectés de façon incor-
recte risquent d'endommager irrémédiablement
l'équipement.
Important:
Do not exceed the controller
electrical ratings. Exceeding controller electrical
ratings can result in permanent damage to the
controller and void any warranty.
Important:
Use copper conductors only. Make
all wiring in accordance with local, national, and
regional regulations.
Important:
Electrostatic discharge can damage
controller components. Use proper electrostatic
discharge precautions during installation,
setup, and servicing to avoid damaging the
controller.

Terminal blocks and bus ports
for terminal block
and bus port locations on the CGM controller.
Observe the following guidelines when wiring a CGM
controller.
Input and Output terminal blocks
On the CGM controller models, the input and
output terminal blocks are removable. All of the
input terminal blocks are mounted on the bottom
of the controller, and the output terminal blocks
are mounted on the top of the controller. For
information about removing a terminal block, see
. For more information
about I/O terminal functions, requirements, and
ratings, see
