3.6.1 Connection to thepower 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 is not relevant for sizes FS2 to FS7.
Pay attention to the phase sequence for frame size FS8!
•
DC+ (or +), DC- (or -), PE for DC link coupling or if the device is being
supplied with DC voltage
•
U, V, W, PE for the input wiring to the motor
•
BR, DC+ (or +), PE for an external braking resistor
•
DC+ (or +) or DC- (or -), PE for connecting all-pole sine filters

The number and the arrangement of the connection terminals used depend
on the DA1 variable frequency drive’s frame size and model.
WARNING
The variable frequency drive must always be connected with
ground potential via a grounding conductor (PE).
