L1, L2, L3
Mains supply connection Mains power supply of the inverters (380–480 V AC,50/60 Hz);(380-500 V – 01800 and above)
P/+, N/−
External brake unit connection
An optional external brake resistor can be connected to the terminals P and N or you can connect a optional high power factor con
-
verter.
P1, P/+
Converter choke coil connection
An optional choke coil can be connected to the terminals P1 and P/+.The jumper on terminals P1 and P/+ must be removed when
this optional choke coil is used on frequency inverter models 01160 and below.The DC reactor supplied with the unit must be installed
on frequency inverter models 01800 and above.
PR, PX
Please do not remove or use terminals PR and PX or the jumper connected.
U, V, W
Motor connection Voltage output of the inverter (3-phase,0 V up to power supply voltage,0,5–400 Hz)
