12-1. General cautions
12. ELECTRICAL WORK
Electrical work should be done by qualified electrical engineers in accordance with "Engineering Standards For Electrical
Installation" and supplied installation manuals. Special circuits should also be used. If the power circuit lacks capacity or
has an installation failure, it may cause a risk of electric shock or fire.
1) Be sure to take power from the special branch circuit.
2) Be sure to install an earth leakage breaker to the power.
3) Install the unit to prevent that any of the control circuit cables (remote controller, transmission cables, or external input/
output line) is brought in direct contact with the power cable outside the unit.
4) Ensure that there is no slack on all wire connections.
5) Some cables (power, remote controller, transmission cables external input/output line) above the ceiling may be bitten
by mouses. Use as many metal pipes as possible to insert the cables into them for protection.
6) Never connect the power cable to leads for the transmission cables. Otherwise the cables would be broken.
7) Be sure to connect control cables to the indoor unit, remote controller, and the outdoor unit.
8) Be sure to ground the unit.
9) Select control cables from the conditions given in P45.
Be sure to put the unit to the ground on the outdoor unit side. Do not connect the earth cable to any gas pipe, water pipe,
lightening rod, or telephone earth cable. Incomplete grounding may cause a risk of electric shock.
