WARNING: Shock Hazard. May result in death or serious injury. Do not connect the
common connection of the power supply/transformer supplying this equipment to any
external ground (earth) connection. Installation and service must be performed by a
licensed professional HVAC installer (or equivalent) or service agency. Do not connect
any common connection or ground (earth) of the sensors and actuators connected to this
equipment to any external ground connection. If necessary, use separate power supplies/
transformers to power sensors or actuators isolated from this equipment.
Intended Use
• T he products described or affected by this document, together with software, accessories, and
options, are controllers, intended for commercial HVAC machines according to the instructions,
directions, examples, and safety information contained in the present document and other
supporting documentation.
• T he product may only be used in compliance with all applicable safety regulations and
directives, the specified requirements, and the technical data.
• P rior to using the product, you must perform a risk assessment in view of the planned
application. Based on the results, the appropriate safety-related measures must be
implemented. Since the product is used as a component in an overall machine or process, you
must ensure the safety of persons by means of the design of this overall system.
• O perate the product only with the specified cables and accessories. Use only genuine
accessories and spare parts.
• A ny use other than the use explicitly permitted is prohibited and can result in unanticipated
hazards.
Unintended Use
• A ny use other than that expressed above under Intended Use is strictly prohibited.
• T he relay contacts supplied are of an electromechanical type and subject to wear. Functional
safety protection devices, specified in international or local standards, must be installed
externally to this device.
Environmental Conditions
• T his equipment must be protected against dripping water or any other liquid water exposure.
The humidity level must be maintained below 90% and without condensation. Further,
installation under cold surfaces must be avoided as it can generate dripping water caused by
condensation. Use of an unventilated enclosure in a high humidity environment may increase
the risk of water damage to the controller.
• T his equipment must be protected against insertion of dust or any particulate material the size
of 0.47 in (12 mm) or less.
WARNING: Fire Hazard. May result in death or serious injury. Equipment must be
protected from outside elements. Install and use this equipment in non-hazardous
locations only.

Step 1: Mount the FCU Controller
WARNING: Shock Hazard. May result in serious injury or death. Disconnect all power
sources before installing or servicing this unit.
T he FCU controller can be either surface or DIN rail mounted. The preferred installation is DIN rail
mounting and requires a 4 DIN wide mounting location. For DIN rail installation, follow the steps below:
• I nstall the controller in an enclosure designed for the specific environmental conditions and
to minimize the possibility of unintended contact with hazardous voltages. All pertinent state,
regional and local safety regulations must be observed when installing and using this product.
• U se of metal enclosures to improve electromagnetic immunity of the controller system is
recommended.

Minimum Clearances
The FCU controller must be installed in an enclosure with the clearances shown below.
Note: Controllers must be mounted horizontally on a vertical plane as shown in the figure below.
Step 2: Wire the thermostat / FCU controller communication link
The FCU controller comes with a 3-wire harness in the LR-HVAC-WIRE-100 package. Connect this
harness to the top left connector on the FCU controller. Run wires to the 3-pin connector on the
thermostat. The 3-wire harness can be extended up to 500 ft (153 m) using one 18 AWG (1.0 mm
and 1 pair 22 AWG (0.5 mm
the drain / shield wire to earth / g round or to the thermostat and do not allow it to contact the grounded
wallbox.
Best Wiring Practices
• I /O and communication wiring must be kept separate from the power wiring. Route these two
types of wiring in separate cable ducting.
• V erify that the operating conditions and environment are within the specification values.
• U se proper wire sizes to meet voltage and current requirements.
• U se copper conductors (required).
• U se twisted pair, shielded cables for analog signals.
