Terminal symbol Purpose Description
L1, L2, L3
(L, N)
Mains supply
Single phase supply: connect to L, N
Three phase supply: connect to: L1, L2, L3
U, V, W
Inverter output Connect a three phase motor
+, - 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. Also to connect cable shield.
