A caunou
Make sure that the input voltage is:
Three phase 380 to 415 V/50 Hz, 400 to 460 V/60 Hz
Be sure not to input a single phase to a 3 phase type.
Otherwise, there is a danger offire.
Be sure not to connect AC power supply to the output terminals
tu (rl), v (r2), w (r3)1.
Otherwise, there is a danger ofinjury and./or fire,
Note:
R (Ll), s (L2), T (L3): Three phase 380 to 4l5V/50 Hz
4fi) to 460V/60 Hz
Power supply
Fasten the scrcws with the specified fastening torque. Check so that there is no
loosening of screws.
Otherwise, there is a danger of frre.
Remarks for using earth leakaqe circuit breakers in the mains supDlv:
Frcquency inverten with CE-filters (RFl-filter) and screened motor cables have a
higher lei*age current against earth. EspecialJy in the moment of switching on this
can cause unintentional triggerings of earth leakage circuit breakers. Because of ihe
rectifier on the input side of the invener there is the possibility to stall the switch-off
function through amounts of DC-current. The following should be observed:
Only shon dme-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 ope.ation circuit.
Otherwise, there is a danger of fire.
As lbr 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 tne inverter. And protection device meeting IEC947-I/IEC947-3 must be fitted at
this point.
Connection to wiring terminal must be reliabily fixed with two means of support.
