used, Max. 50 m, 164 ft

If 2.5 mm
used and S3 separated, Max. 80 m, 262ft
*2. The 10 m, 30 ft wire is attached in the remote controller accessory. Max 1500 ft
*3. The fi gures are NOT always against the ground.
S3 terminal has DC 24 V against S2 terminal. However between S3 and S1, these terminals are NOT electrically insulataed by the transformer or other device.
*4. Use earth leakage breaker (NV)
Make sure that the current leakage breaker is one compatible with higher harmonics as this unit is equipped with an inverter.
The use of inadequate breaker can cause the incorrect operation of inverter.
Notes: 1. Wiring size must comply with the applicable local and national code.
2. Use copper supply wires.
3. Use wires rated 600V or more for the power supply cables and the indoor/outdoor unit connecting cables.
4. Install an earth longer than other cables.
Warning:
In 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.
Warning:
• Turn on the main power when the ambient temperature is -20°C, -4°F or higher.
• In below -20°C, -4°F condition, it needs at least 4hr standby to operate in order to warm the electrical parts.
Never splice the power cable or the indoor-outdoor connection cable, otherwise it may result in a smoke, a fi re or communication failure.
