Connection to Power Section
The following figure shows the general connections for the
frequency inverter in the power section.
Three-Phase Input Connection
Terminal Designations in the Power Section
●
L1, L2, L3: Connection terminals for the supply voltage
(input, input voltage):
●
Three-phase AC voltage: Connection to: L1, L2, L3 with
HMX32_ and HMX34_.
●
U/T1, V/T2, W/T3: Connection terminals for the
three-phase line to the AC motor (output, frequency
inverter)
●
PE: connection for protective ground (reference
potential). PES with mounted cable routing plate for
shielded cables
Connection to Power Section
Ground Connection
The ground connection is connected directly with the cable
clamp plates.
The shielded cables between the frequency inverter and the
motor should be as short as possible. Connect the shielding
on both ends and over a large surface area with protective
ground PES (Protective Earth Shielding). You can connect the
shielding of the motor cable directly to the cable clamp plate
(360 degrees coverage) with the protective ground.
The frequency inverter must always be connected to the
ground potential via a grounding cable (PE).
