Electrical wiring work

When installing outdoor units in module, select the power supply cable according to the sum of outdoor unit capacity.
(Refer to the table for each model)
ex) Outdoor unit installation (AM100FXW + AM120FXW )
This device is intended for the connection to a power supply system with a maximum permissible system impedance shown in the table (on
the left page) at the interface point (power service box) of the user's supply.
The user must ensure that this device is connected only to a power supply system which fulfills the requirement above. If necessary, the user
can ask the public power supply company for the system impedance at the interface point.
This equipment complies with IEC 61000-3-12 provided that the short-circuit power Ssc is greater than or equal to Ssc(*2) at the interface point
between the user's supply and the public system. It is the responsibility of the installer or user of the equipment to ensure, by consultation
with the distribution network operator if necessary, that the equipment is connected only to a supply with a short-circuit power Ssc greater
than or equal to Ssc(*2).

Caution for electrical work
You must install ELCB or MCCB + ELB
- ELCB: Earth leakage breaker
- MCCB: Molded case circuit breaker
- ELB: Earth leakage breaker
Do not operate the outdoor unit before completing the refrigerant pipe work.
Do not disconnect or change the cable inside the product. It may cause damage to the product.
Specification of the power cable is selected based on following installation condition; culvert installation/ambient temperature 30 °C/ single
multi conductor cables. If the condition is different from the ones stated, please consult an electrical installation expert and re-select the power
cable.
- If the length of power cable exceed 50m, re-select the power cable considering the voltage drop.
Use a power cable made out of incombustible material for the insulator (inner cover) and the sheath (outer cover)
Do not use the power cable with the core wire exposed due to insulator damage occurred during removal of the sheath.
When the core wire is exposed, it may cause fire.
