IC-664 INSTALLATION GUIDE
4
3. General installation guidelines
3.1 IC-664 Control
•
It is recommended to install the unit in a hallway to limit the IC-664’s exposure to noxious gases.
•
In order to avoid condensation problems inside the controller, it is recommended to install the
IC-664 on an inside wall. If it is not possible, use spacers to have an air gap between the wall
and the IC-664.
•
It is required to install the IC-664 side up with the cable entry holes facing down (see figure 1).
•
The enclosure is watertight, but not splash proof or immersion proof. DO NOT WATER the
control. Cover it carefully with plastic when cleaning the room.
•
The IC-664 should be installed in easy access location but away from damaging elements
(heat, cold, water, direct sunlight, …).
•
It is recommended to punch out knock outs by striking them at the bottom near the back of
the case (see figure 2).
•
Do not drill the face, the side, the top or the underside of the control.
•
Do not install the IC-664 control near high voltage equipment, power supply or transformer.
3.2
Electrical
Cables
•
All electrical cables must be installed according to local wiring codes.
•
All cable shields must be connected to the IC-664 power ground only, except for the cable
connected to the optional PC interface (see SVPC-40 guide). The shield is needed to protect
the IC-664 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 IC-664.
•
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
conduit.
•
If a low voltage cable have 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 750 ‘ (250m) or less.
•
It is prohibited to use overhead cable outside the building.
3.3 Electrical Power
•
Protection from electrical surge should be included in the planning of each installation.
•
Every module should have a separate breaker to avoid serious consequences.
•
Certain control modules (VSM-2, VSM-2/2, VPM-2, VPM-1 and CIP-1) require the same
phase and same voltage as the IC-664 to operate.
•
It is strongly recommended to put a backup power source to ensure life-sustaining conditions
in case of power failure (see figure 5).
•
It is also strongly recommended to put a backup thermostat to sufficient fan and heating
system parallel to the IC-664 module output (see figure 6).
•
Backup system and alarm must be thoroughly tested and verified as working properly before
using the ventilation system.
