14. Electrical wiring
WARNING
Electrical work should be done by a qualified electrical contractor in accordance with
"Engineering Standards for Electrical Installation" and supplied installation manuals. If the
power circuit lacks capacity or has an installation failure, it may cause a risk of electrical
shock or fire.
• Be sure to follow local and national code requirements when wiring these units.
• Install the unit in a manner to prevent that any of the control circuit cables (remote
controller, transmission cables) are brought in direct contact with the power cable
outside the unit.
• Ensure that there is no tension on any wire connections.
• Some cables (power, remote controller or transmission) above the ceiling may become
damaged by accident or by animals. Use conduit as much as possible to prevent
damage.
• Never connect the power cable to leads for the transmission cables. The cables will
break.
• Be sure to connect control cables to the indoor unit, remote controller and the outdoor
unit.
• Perform wiring in compliance with the safety regulations detailed in UL 1995.
• Be sure to install an earth leakage breaker to the power.
• Install the unit in a way that prevents any of the control circuit cables (remote controller,
transmission cables) that are brought in direct contact with the power cable outside the
unit.
• Ensure that there is no slack on all wire connections.
CAUTION
Be sure to ground the unit. Do not connect the grounding cable to any gas pipe, water
pipe, lightening rod, or telephone earth cable. Incomplete grounding may cause a risk of
electrical shock. If the supply cord is damaged, it must be replaced by the manufacturer, its
service agent or similarly qualified persons in order to avoid a hazard.
Specifications are subject to change without notice.
