General installation guidelines
CPS-2C Control
It is recommended to install the unit in a hallway to limit the CPS-2C exposure
-
to noxious gases.
In order to avoid condensation problems inside the controller, it is
-
recommended to install the CPS-2C on an inside wall. If it is not possible, use
spacers to have an air gap between the wall and the CPS-2C.
It is required to install the CPS-2C side up with the cable entry holes facing
-
down.
-
The enclosure is watertight, but do not spray water or immerse the CPS-2C in
water. Cover it carefully with plastic when cleaning the room.
The CPS-2C 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 rear of the control.
-
Do not install the CPS-2C control 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 CPS-2C power ground only,
-
except for the cable connected to the optional PC interface. The shield is
needed to protect the CPS-2C 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 ground of the CPS-2C.
-
Use separate conduit 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.
