DANGER
Burnout
●Risk of burnout of the motor!!
Prohibited
 Do not drive a 200 V class motor with a 400 V class inverter.
Do
 The input power supply should be within the following ranges.
 200 V class 200 to 240 VAC (allowable fluctuation range +10%/-15%)
 400 V class 380 to 480 VAC (allowable fluctuation range +10%/-15%),
 Power supply frequency 50 Hz/60 Hz (fluctuation range ±5%) for both 200 V/
400 V classes
Fire
Damage
● Risk of fire and damage to machine!
Do
 For connection between the power supply and the main power input terminal
([R/L1] terminal, [S/L2] terminal, [T/L3] terminal), use the earth-leakage breaker
for protecting the circuit (wiring).
 If the protection function of the inverter is activated, there is a possibility that a
failure or an accident is occurring on your system. Connect a magnetic
contactor that shuts off the power supplied to the inverter.
 Since the earth-leakage breaker may malfunction due to effects of high
frequency, please use a model with large high-frequency sensitive current
value.
