ELECTRICAL HAZARDS:
• Shutdown and/or disconnect all electrical power to the unit before performing inspections, maintenance, or
service.
• Make sure to follow proper lockout/tag out procedures.
• Always work in the company of a qualied assistant if possible.
• Capacitors, even when disconnected from the electrical power source, retain an electrical charge potential
capable of causing electric shock or electrocution. Wait a few minutes after shutdown to allow the capacitors to
discharge the stored energy.
• Handle, discharge, and test capacitors according to safe, established, standards, and approved procedures.
• Extreme care, proper judgment, and safety procedures must be exercised if it becomes necessary to test or
troubleshoot equipment with the power turned on to the unit.
• Do not spray water on the air conditioning unit while the power is on.
• Electrical component malfunction caused by water could result in electric shock or other electrically unsafe
conditions when the power is restored and the unit is turned on, even after the exterior is dry.
• Use air conditioner on a single dedicated circuit within the specied amperage rating.
• Ensure the unit that the unit is properly grounded.
• Do not cut or modify the power supply cord or remove the ground prong of the plug.
• Never operate the unit on an extension cord.
• Follow all safety precautions and use approved protective safety equipment such as: gloves, goggles, and
clothing. Ensure that properly insulated tools, and testing equipment are are used as well to protect against
equipment damage and reduce the risk of injury.
• Failure to follow proper safety procedures and these warnings can result in serious injury or possibly death.

Electric characteristics
- The power supply work is needed only to the outdoor unit. The power supply to the indoor unit is conducted through the
communication wiring. Therefore, the power supply work can be carried out at just one place of the outdoor unit. It will
simplify the work procedure and save cost.
- Wiring cable size must comply with the applicable local and national codes.

Electric characteristics
Notes :
(compressor or other motor)
- Load2 : sum of current for all other motors
- Load3 : any other load rated 1.0A or more
1. Voltage range
Voltage supplied to the unit terminals should be within the
minimum and maximum range
2. Maximum allowable voltage unbalance between phase is 2 %
3. MCA / MOP
MCA = (1.25 x Load1) + Load2 + Load3
MOP = (2.25 x Load1) + Load2 + Load3
- Load1 : Rated running current of largest motor
4. Select wire spec. based on the MCA
5. Recommended circuit breaker is ELCB (Earth Leakage circuit
breaker)
6. MSC & RLA are measured as the compressor only test
condition.
7. OFM is measured as the outdoor unit test condition
