General installation guidelines
Controller
-
It is recommended to install the unit in a hallway to limit the controller exposure to
noxious gases.
-
In order to avoid condensation problems inside the controller, it is recommended to
install the controller on an inside wall. If it is not possible, use spacers to have an air
gap between the wall and the controller.
-
It is required to install the controller right side up with the cable entry holes facing
down.
-
The enclosure is watertight, but do not spray water or submerge the controller in
water. Cover it carefully with plastic when cleaning the room.
-
The controller should be installed in easy-access location but away from damaging
elements (heat, cold, water, direct sunlight, ...).
-
Do not drill the face, the side, the top or the underside of the control.
-
Do not install the controller near high-voltage equipment, power supply or
transformer.
Electrical cables
-
All electrical cables must be installed according to local wiring codes.
-
All cable shields must be connected to the shield terminal on the cord to which the
cable is connected, except for the cable connected to the optional PC interface. The
shield is needed to protect the controller and the modules against any electromagnetic
interference generated by lightning or nearby operating machinery.
-
Never use the shield as a conductor.
-
Connect only one end of the shield to the controller.
-
Use separate conduits for the low voltage cables (communication and probes) and the
high voltage cables. There must be at least 1 foot (30 cm) between low-voltage and
high-voltage conduits.
-
If a low voltage cable has to cross over a high voltage cable, make this crossing at
90°.
-
All cable connections must be soldered or done with approved sealed connectors.
Probe cables must be 500' (150m) or less.
-
Communication cables must be 820' (250m) or less.
-
-
It is prohibited to use overhead cables outside the building.
Electrical power
-
Protection from electrical surges should be included in the planning of each
installation.
-
Every module should have a separate breaker to avoid unwanted consequences.
-
The V2 and V1 modules require the same voltage and phase as the VAR BOARD
(X1204 or X1418) power source.
-
The OUT1 and OUT2 outputs require the same phase and same voltage as the
controller to operate.
-
It is strongly recommended to have a backup power source to ensure life-sustaining
conditions in case of power failure (see figure 8).
