CPS-2C INSTALLATION
CPS-2C Section B-9
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.
