4. WIRING DESIGN
4-1. ELECTRICAL WIRING
PRECAUTION FOR ELECTRICAL WIRING
Regulations for wire diameter and selecting circuit breaker size dier from locality.
Always install in accordance with local standards.
WARNING
● Do not turn on the power until all installation work is complete.
● Before starting work, check that power is not being supplied to the unit.
● Connect the connection cable rmly to the terminal board. Imperfect installation may cause re.
● Always install a circuit breaker for each power supply circuit. Failure to use a circuit breaker could
result in electrical shock or re.
● Always install a disconnect switch for each power supply circuit.
● Always connect the ground wire.
● Never install a condenser for improving the power factor. (It will not improve the power factor and
the condenser will become abnormally hot.)
● When installing this system in high humidity locations, install using Ground Fault Equipment
Breaker (GFEB) to reduce the risk of leaking current which may result in electric shock or potential
re.
CAUTION
● When approved for use in local code, we suggest installing Ground Fault Equipment Breaker (GFEB).
In that case, GFEB shall be per Fujitsu recommended capacity in order to prevent malfunction of
breaker device.
● Always use a dedicated power circuit for each condensing unit (outdoor unit). Never use a power
supply shared by another appliance.
● "Wire size" and "Breaker" are for reference only; always install according to local regulations.
● Make the wire length between disconnect switch and unit terminal as short as possible provided
that it complies with local code.
● Installation and service of this product is only to be performed by qualified professionals.
● All field wiring and components must be provided by a licensed electrician.
● Use copper conductors only.
● Use crimp-type terminals and tighten the terminal screws to the specified torques, otherwise,
abnormal overheating may be produced and possibly cause serious damage inside the unit.
