Mains supply
Single phase supply: connect to L1, N
Three phase supply: connect to: L1, L2, L3
U, V, W bzw.
T1, T2, T3
Inverter output Connect a three phase motor

reactor
Normally a short bar is attached between
ter1 and +. When a DC reactor is to
be connected, remove the short bar first.

External rege-
nerative resistor
An optional regenerative resistor can be
connected here.
+, - Braking unit
Connect the optional braking unit (when high
braking torque is required).
Grounding
Ground must be connected to prevent electric
shock should the inverter case carry
dangerous voltages due to a malfunction.
