Electric Wiring
Warning
Only properly trained and qualified personnel are allowed to perform wiring
work.
Before wiring, you must disconnect the power. Do not work under any
energized conditions.
Supply power from a stable source that is free from the effect of surge.
Ensure that a Ground Fault Circuit Interrupter (GFCI) with appropriate capacity
for earth leakage and load is used in the power supply of the product to prevent
electrical shock and burnout of the compressor motor. See “6-1 List of
specifications” for details.
Supply power of the product should meet the specifications on page 6-1.
The product must be grounded for safety.
Do not connect ground wire to a water pipe, a gas pipe, or a lightening rod.
Take care not to overload the power supply by connecting multiple units to one
supply.
The customer must prepare for countermeasures of the power failure.
The dryer may not start normally at the moment of power failure.
Circuit breaker must be properly selected to meet safety standard of local
regulations.
Always be sure to connect the protective conductor first, disconnect it last in
respect to the other connections.
Be sure that the protective conductor has some additional length in respect to
the live conductors, so that it is not subject to mechanical stresses.
Be sure to install the circuit breaker correctly so that it disconnects all live
conductors and so that the operating handle can be easily accessible.
Specification of power cable
Prepare following power cable.
Power cable: 1.25mm
2
(16AWG), Three-cores (including the ground cable), External diameter: about 8
to 12mm.
Additional length of about 0.1m (4in) is needed to wire inside of the product.
Length of the power cable
The maximum length of the power cable should be no more than 98ft (30m).
Connecting to the power supply
Connect the power cable and the ground to the terminal block. Make sure to use the ring terminals for
M3 screws.
Applicable crimped terminal: 1.25-3 (Width: 6.5mm and below)
Wiring procedure
Remove the terminal block cover or the rear panel.
Insert the cord through the rubber grommet and connect it to the terminal block (refer to the label on
the terminal block).
M3 screw tightening torque: 0.6 to 1Nm
During wiring work, do not touch other sections except terminal block.
Re-attach the cover or real panel after wiring is done.
