J300 INSTRUCTION MANUAL

CAUTION
Make sure that the input voltage is :
Three phase 200 to 220V/50Hz, 200 to 230V/60Hz
Three phase 380 to 415V/50Hz, 400 to 460V/60Hz
Be sure not to input a single phase to a 3 phase type.
Otherwise, there is a danger of fire.
Be sure not to connect AC power supply to the output terminals
[U (T1), V(T2), W(T3)].
Otherwise, there is a danger of injury and/or fire.
Fasten the screws with the specified fastening torque. Check so that there is no loosening of
screws.
Otherwise, there is a danger of tire.
Frequency inverters with CE-filters (RFI-filter) and screened motor cables have a higher leakage
current against earth. Especially in the moment of switching on this can cause unintentional
triggerings of earth leakage circuit breakers. Because of the rectifier on the input side of the
inverter there is the possibility to stall the switch-off function through amounts of DC-current.
The following should be observed:
Only short time-inveriant and pulse current-sensitive earth leakage circuit breakers with higher
trigger current should be used.
Other components should be secured with separate earth leakage circuit breakers.
Earth leakage circuit breakers in front of an inverter are not an absolute protection against
direct touching.
Be sure to set the fuse(s) (the same phase as the main power supply) in the operation circuit.
Otherwise, there is a danger of fire.
As for motor leads, earth leakage breakers and electromagnetic contactors, be sure to use the
equivalent ones with the specified capacity (rated).
Otherwise, there is a danger of fire.
Double pole disconnection device must be fitted to the incoming mains supply close to the
inverter. And protection device meeting IEC947-1/IEC947-3 must be fitted at this point.
Connection to wiring terminal must be reliabily fixed with two means of support.
