3.6.1 Connection to power section
The connection to the power section is normally made via the connection
terminals:
•
L1/L, L2/N, L3, PE for the mains-side supply voltage.
The phase sequence does not matter.
•
DC+, DC-, PE for DC link coupling
•
U, V, W, PE for the connection to the motor
•
BR, DC+, PE for an external brake resistor

Connection in power section (schematic)
The number and the arrangement of the connection terminals used depend
on the variable frequency drive’s size and model.
NOTICE
The variable frequency drive must always be connected with
ground potential via a grounding conductor (PE).
