Electrical Precautions
Take the following precautions to reduce the risk of electric shock, fi re or explosion
resulting in serious injury or death:
●Only use electrical protection equipment and tools suited for this installation.
●Insulate the controller against moisture and temperature extremes.
●Use specifi ed cables between units and the controller.
●Communication cabling must be a minimum of 18-Gauge, 2-Conductor, Shielded Stranded Copper.
Shielded cable must be used in all areas to reduce the potential for communication errors.
When shielded cabling is applied, proper bonding and termination of the cable shield is required as per Johnson
Controls guidelines. Plenum and riser ratings for communication cables must be considered per application and
local code requirements.
●The polarity of the input terminals is important, so be sure to match the polarity when using contacts that have
polarity.
●Highly dangerous electrical voltages may be used in this system. Carefully refer to the wiring diagram and these
instructions when wiring. Improper connections and inadequate grounding can cause serious injury or death.
●Before installing the controller or remote devices, ensure that the indoor and outdoor unit operation has been
stopped. Further, be sure to wait at least fi ve minutes before turning off the main power switch to the indoor or
outdoor units. Otherwise, water leakage or electrical breakdown may result.
●Do not open the service cover or access panel to the indoor or outdoor units without turning OFF the main
power supply. Before connecting or servicing the controller or cables to indoor or outdoor units, open and tag all
disconnect switches. Never assume electrical power is disconnected. Verify with a meter and equipment.
●Use an exclusive power supply at the controller’s rated voltage.
●Be sure to install circuit breakers (ground fault interrupter, isolating switch, molded case circuit breaker, and so
forth) with the specifi ed capacity. Ensure that the wiring terminals are tightened securely to recommended torque
specifi cations.
●Clamp electrical wires securely with a cord clamp after all wiring is connected to the terminal block.
In addition, run wires securely through the wiring access channel.
●When installing the power lines, do not apply tension to the cables. Secure the suspended cables at regular
intervals, but not too tightly.
●Make sure that the terminals do not come into contact with the surface of the electrical box.
If the terminals are too close to the surface, it may lead to failures at the terminal connection.
●Do not clean with, or pour water into, the controller as it could cause electric shock and/or damage the unit.
Do not use strong detergent such as a solvent. Clean with a soft cloth.
●Verify that the ground wire is securely connected. Do not connect ground wiring to gas piping, water piping,
lighting conductor, or telephone ground wiring.
