Ƶ.Electric Wiring Work
Ƶ.1 Wiring Precautions
WARNING!
Before obtaining access to terminals, all supply circuits must be disconnected.
The rated voltage of the unit is as shown as Table 1-4-1 and Table 1-4-2
Before turning on, verify that the voltage is within the 187~252V range (for single phrase units).
Always use a special branch circuit and install a special receptacle to supply power to the air conditioner.
Use a special branch circuit breaker and receptacle matched to the capacity of the air conditioner.
The special branch circuit breaker is installed in the permanent wiring. Always use a circuit that can trip all the poles
of the wiring and has an isolation distance of at least 3mm (1/8inch) between the contacts of each pole.
Perform wiring work in accordance with standards so that the air conditioner can be operated safely and positively.
Install a leakage special branch circuit breaker in accordance with the related laws and regulations and electric
company standards.
WARNING!
The power source capacity must be the sum of the air conditioner current and the current of other electrical
appliances. When the current contracted capacity is insufficient, change the contracted capacity.
When the voltage is low and the air conditioner is difficult to start, contact the power company to raise the voltage.
