ELECTRICAL WIRING

The precautions of electrical wiring
•
Wiring connections must be performed by a qualified person in accordance with specifications.
The rated supply of this product is 60Hz, 208/230V. Use a voltage within the range of 187-264V.
•
Before connecting the wires, make sure the power supply is OFF.
•
When installing this system in high humidity locations, install using ground fault equipment breakers (often
referred to in other countries as an ELCB earth leakage current breaker) to reduce the risk of leaking current
which may result in electric shock or potential fire.
•
Be sure to install a breaker of the specified capacity. When selecting breaker, please comply with the laws and
the regulations of each country. One breaker must be installed on the power supply of the outdoor unit. Wrong
selection and setup of the breaker will cause electric shock or fire.
•
Do not connect AC power supply to the transmission line terminal board.
Improper wiring can damage the entire system.
•
Connect the connector cord securely to the terminal.
Faulty installation can cause a fire.
•
Make sure to secure the insulation portion of the connector cable with the cord clamp. A damaged insulation can
cause a short circuit.
•
Never install a power factor improvement condenser. Instead of improving the power factor, the condenser may overheat.
•
Before servicing the unit, turn the power supply switch OFF. Then, do not touch electric parts for 10 minutes due
to the risk of electric shock.
•
Make sure to perform grounding work. Improper grounding work can cause electric shocks.
•
The primary power supply capacity is for the air conditioner itself, and does not include the concurrent use of
other devices.
•
Do not use crossover power supply wiring for the outdoor unit.
•
If the electrical power is inadequate, contact your electric power company.
•
Install a breaker in a location that is not exposed to high temperatures.
If the temperature surrounding the breaker is too high, the amperage at which the breaker cuts out may
decrease.
•
We suggest installing GFEB breakers or follow local electrical code. This system uses an inverter, which means that
when used with a ground fault breaker you must use breakers that can handle higher harmonics such as a (GFEB)
Ground Fault Equipment Breaker (30 mA or greater) in order to prevent malfunctioning of ground fault device.
•
When the electrical switchboard is installed outdoors, place it under lock and key so that it is not easily
accessible.
•
Do not fasten the power supply cable and connection cable together.
•
Always keep to the maximum length of the connection cable. Exceeding the maximum length may lead to
erroneous operation.
•
The static electricity that is charged to the human body can damage the control PC Board when handling the
control PC Board for address setting, etc.
Please keep caution to the following points.
Provide the grounding of Indoor unit, Outdoor unit and Option equipment.
Cut off the power supply (breaker).
Touch the metal section (such as the unpainted control box section) of the indoor or outdoor unit for more than
10 seconds. Discharge the static electricity in your body.
Never touch the component terminal or pattern on the PC Board.
