Power supply
z
A power switch is equipped beside the terminal block.
z
The voltage of AC power source is free between 100 V and 240 V AC.
z
The terminal screws of the power source are M4 type.
z
The applicable electric wire is of 0.75 mm
2
to 5.5 mm
2
(AWG18 to AWG10).
z
Provide a power switch near the converter so that the power can be turned ON/OFF.
Note
z
The operation of this equipment at any voltage outside the rated range may cause damage.
z
It is recommended that the fluctuations in power supply voltage fall within a range of
±
10
%
.
Connect the power cable and the grounding cable as illustrated below.
Q
Instructions for grounding
Separate this grounding from any other grounding for electric equipment such as the motor.
WARNING
If there is a possibility of a lightning strike, install an arrester on the output side and receiving
instrument side of the converter.
Electric shock hazard
Be sure to turn OFF the power before wiring power source.
WARNING
