DANGER!
Provide an AC disconnecting switch to switch OFF the input
power to the inverter. This device shall disconnect the inverter
from the AC input supply when required (e. g. during
maintenance services).
ATTENTION!
A contactor or another device that frequently disconnects and
reapplies the AC supply to the inverter in order to start and
stop the motor may cause damage to the inverter power
section. The drive is designed to use control input signals for
starting and stopping the motor. If used, the input device must
not exceed one operation every 6 minutes otherwise the
inverter may be damaged.
ATTENTION!
The AC input for the inverter must have a grounded neutral
conductor.
NOTE!
TheAC input must be compatible with the inverter rated voltage
Power supply line capacity:
30 kA rms symmetrical amperes, 200-480 Vac maximum,
when protected by fuses rated maximum of 200 % device
input current. Voltage is the same as the device maximum
input voltage. In order to comply with the UL standard, UL
recognized fuses must be used.
