*1
A breaker with at least 3.0 mm contact separation in each pole shall be provided. Use earth leakage breaker (NV).
Make sure that the current leakage breaker is one compatible with higher harmonics.
Always use a current leakage breaker that is compatible with higher harmonics as this unit is equipped with an inverter.
The use of an inadequate breaker can cause the incorrect operation of inverter.
*2
(ZM100–140)
Maximum 45 m
If 2.5 mm² is used, maximum 50 m.
If 2.5 mm² is used and S3 is separated, maximum 80 m
Maximum 80 m. Total maximum including all indoor/indoor connection is 80 m.
*3
Maximum 500 m (When using 2 remote controllers, the maximum wiring length for the remote controller cables is 200 m.)
*4
The figures are NOT always against the ground.
S3 terminal has 28 VDC against S2 terminal. However between S3 and S1, these terminals are NOT electrically insulated by the transformer or other device.
*5. In multi-phase appliances, the colour of the neutral conductor of the supply cord, if any, shall be blue.
Caution: Be sure to install N-Line. Without N-Line, it could cause damage to the unit.
Notes: 1. Wiring size must comply with the applicable local and national code. .
2. Power supply cables and Indoor/Outdoor unit connecting cables shall not be lighter than polychloroprene sheathed flexible cable.
(Design 60245 IEC 57)
3. Install an earth line longer than power cables.

Outdoor Unit
Warning:
In the case of A-control wiring, there is high voltage potential on the S3 terminal caused by electrical circuit design that has no electrical insulation between
power line and communication signal line. Therefore, please turn off the main power supply when servicing. And do not touch the S1, S2, S3 terminals
when the power is energized. If isolator should be used between indoor unit and outdoor unit, please use 3-pole type.
