DIP-1C INSTALLATION
DIP-1C Section B-9
General installation guidelines
DIP-1C Module
-It is recommended to install the unit in a hallway to limit the DIP-1C exposure
to noxious gases.
-In order to avoid condensation problems inside the module, it is
recommended to install the DIP-1C on an inside wall. If it is not possible, use
spacers to have an air gap between the wall and the DIP-1C.
-It is required to install the DIP-1C side up with the cable entry holes facing
down.
-The enclosure is watertight, but do not spray water or immerse the DIP-1C in
water. Cover it carefully with plastic when cleaning the room.
-The DIP-1C 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 module.
-Do not install the DIP-1C 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 DIP-1C power ground only, except
for the cable connected to the optional PC interface and to the ventilation
controllers. The shield is needed to protect the DIP-1C 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 DIP-1C.
-Use separate conduit for the low voltage cables (communication) 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.
-Communication cables must be 820’ (250m) or less.
-It is prohibited to use overhead cables outside the building.

DIP-1C INSTALLATION
Section B-10 DIP-1C
Electrical Power
-Protection from electrical surge should be included in the planning of each
installation.
-It is strongly recommended to have a backup power source to ensure life-
sustaining conditions in case of power failure (see figure 2).
-The backup system and alarm must be thoroughly tested and verified as
working properly before using the ventilation system.
Mounting
-The enclosure must be mounted in a location that will allow the cover to be
completely opened right up against the wall.
-Fasten the four brackets to the four mounting holes on the back of the
enclosure, using the four screws provided with the brackets.
-Then mount the enclosure on the wall by inserting screws through the
brackets’ adjustment slots, into the wall. Make sure to position the enclosure
so that all wires extend out of the bottom section of the enclosure.
-The bracket slots also serve to adjust the position of the module.
-Once you have adjusted the module position, tighten the four mounting
screws.
