JD-N2 INSTALLATION
JD-N2
Section B-8
General installation guidelines
JD-N2 Control
-
It is recommended to install the unit in a hallway to limit the JD-N2 exposure
to noxious gases.
-
In order to avoid condensation problems inside the controller, it is
recommended to install the JD-N2 on an inside wall. If it is not possible, use
spacers to have an air gap between the wall and the JD-N2.
-
It is required to install the JD-N2 right side up with the cable entry holes facing
down.
-
The enclosure is watertight, but do not spray water or immerse the JD-N2 in
water. Cover it carefully with plastic when cleaning the room.
-
The JD-N2 should be installed in easily accessible 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 JD-N2 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 JD-N2 power ground only. The
shield is needed to protect the JD-N2 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 JD-N2.
- Use separate conduit for the low voltage cables (communication,
potentiometer 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.
-
It is prohibited to use overhead cables outside the building.
