A main switch or other means of disconnection, having a contact separation in all poles, must be incorporated in the
fixed wiring in accordance with relevant local laws and regulations. Switch off the power supply before making any
connections. Use only copper wires. Never squeeze bundled cables and make sure they do not come in contact with
the piping and sharp edges. Make sure no external pressure is applied to the terminal connections. All field wiring and
components must be installed by a licensed electrician and must comply with relevant local laws and regulations.
The field wiring must be carried out in accordance with the wiring diagram supplied with the unit and the instructions
given below.
Be sure to use a dedicated power supply. Never use a power supply shared by another appliance.
Be sure to establish a ground. Do not ground the unit to a utility pipe, surge protector, or telephone ground. Incomplete
grounding may cause electrical shock.
Be sure to install a ground fault circuit interrupter (30 mA). Failure to do so may cause electrical shock.
Be sure to install the required fuses or circuit breakers.
WARNING
The ground fault circuit interrupter must be a high- speed type breaker of 30 mA (<0.1 s).
NOTE
This unit is equipped with an inverter. Installing a phase advancing capacitor not only will reduce the power factor
improvement effect, but also may cause abnormal heating of the capacitor due to high-frequency waves. Never install a
phase advancing capacitor as it could lead to an accident.
Secure the electrical wiring with cable ties as shown in figure so that it does not come in contact with the piping, particularly
on the high-pressure side.
Make sure no external pressure is applied to the terminal connectors.
When installing the ground fault circuit interrupter make sure that it is compatible with the inverter (resistant to high frequency
electrical noise) to avoid unnecessary opening of the ground fault circuit interrupter.
Fix cables so that cables do not make contact with the pipes (especially on the high pressure side).
8.1 Precautions on electrical wiring work
8 OUTDOOR UNIT WIRING
8.2 Precautions on wiring of power supply
Use the correct screwdriver to tighten the terminal screws. Small screwdrivers can damage the screw head and prevent
appropriate tightening.
Over-tightening the terminal screws can damage the screws.
Attach a ground fault circuit interrupter and fuse to the power supply line.
In wiring, make certain that prescribed wires are used, carry out complete connections, and fix the wires so that outside force
cannot affect the terminals.
Use a round crimp-style terminal for connection to the power supply terminal board. In case it cannot be used due to
unavoidable reasons, be sure to observe the following instructions.
Do not connect different gauge wires to the same power supply terminal. (Loose connections may cause overheating.)
When connecting wires of the same gauge, connect them according to the figure below.
