WARNINGS AND PRECAUTIONS
Although the manufacturer has made every effort to ensure the accuracy of the
information contained herein, this document is subject to change without notice due to
ongoing product development.
WARNINGS AND PRECAUTIONS
Equipment, probe failure, blown fuses and/or tripped breakers may prove harmful to the
contents of the building. Therefore it is strongly recommended to install backup devices
and alarm or warning devices. Spare equipment should also be available at the owner’s
site. Equipment manufactured by the manufacturer is protected against normal line
surges. High surges caused by thunder storms or power supply equipment may damage
this equipment. For added security against line voltage surges it is recommended that
surge and noise suppression devices be installed at the electrical distribution panel. Use
of shielded cable for probes is recommended for protection against lightning. These
devices are available from most electrical supply distributors.
RECOMMENDATIONS
The manufacturer recommends that all installation procedures described herein be
performed by a qualified electrician or installation technician. Furthermore the
manufacturer recommends to test all the functions and equipment connected to the JD-
N2, including the alarm system and backup devices, after installation, after changes to
the installation and every month after that.
Fuse verification and replacement, as well as the proper setting of control values shall
be the responsibility of the owner of this equipment.

(PROBE WIRING) SHIELDED WIRE AWG #22, 500ft (150m) MAXIMUM
LENGTH.
HIGH VOLTAGE WIRE INSTALLED ACCORDING TO LOCAL WIRING CODE.
INSTALL LOW VOLTAGE WIRES (PROBES, COMPUTER LINK OR
POTENTIOMETER WIRES) AT LEAST 12in. (30cm) AWAY FROM HIGH
VOLTAGE WIRES (120/230VAC, 24VDC). ALWAYS CROSS HIGH AND LOW
VOLTAGE WIRES AT A 90-DEGREE ANGLE.
RELAYS: 12A @ 240VAC RESISTIVE, MOTOR 1HP @ 240VAC, 1/2HP @
120VAC AT EACH OUTPUT.
1 WIRE ONLY PER GREEN TERMINAL. USE WIRE CONNECTOR IF YOU
WANT TO CONNECT MORE THAN 1 WIRE, NO BIGGER THAN AWG #12,
NO SMALLER THAN AWG #28.
CHECK INSTALLATION GUIDE FOR ALARM WIRING.
USE SHIELD FOR SHIELDING PURPOSE ONLY. CONNECT THE SHIELD TO
GROUND PLATE . NEVER LEAVE THE SHIELD UNCONNECTED AT BOTH
ENDS. NEVER CONNECT BOTH ENDS OF THE SHIELD TO GROUND
PLATE . THE USE OF A SHIELD FOR ALL PROBES IS MANDATORY.

JD-N2 INSTALLATION
JD-N2 Section B-7
This section will inform the electrician on proper wiring and installation
procedures for the JD-N2.
The manufacturer recommends that the following installation instructions be
followed as closely as possible, and that all work be performed by a certified
electrician. Failure to do so may void the warranty.
Unpacking
Unpack the JD-N2 and inspect contents for damage. Should the contents appear
to be damaged, contact your local distributor to return the material.
The package should contain the following standard items:
1 JD-N2 control
4 Brackets / 4 screws
1 2004-10K inside temperature probe (30 feet cable)
1 Installation / User’s Guide
Mounting Hardware Required
This is the list of the mounting hardware needed, which is not included with the
product:
Shielded two-wire cable, AWG #22 (to extend probes).
4 screws (to hang the unit onto the wall).
Screwdrivers.
Soldering iron kit or approved sealed connectors.
Drill and hole saw kit
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.
JD-N2 INSTALLATION
JD-N2 Section B-9
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 3).
-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 controller.
-Once you have adjusted the controller position, tighten the four mounting
screws.

Connection Procedure
Detailed Wiring Diagrams
Typical Sensor Wiring for Probes
The inside temperature sensor should be located in the area which gives the
most accurate temperature reading to achieve optimum ventilation. The sensor
should also be connected to the JD-N2 with a shielded two-wire cable. It should
be located in an area protected from operating machinery, animal bites,
personnel or anything that could damage the sensor. See also “General
installation guidelines”.
