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-invariant 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.
