4.4. Drive and motor connections
For 1 phase supply power should be connected to L1/L, L2/N.
For 3 phase supplies power should be connected to L1, L2, L3. Phase sequence is not important.
The Motor should be connected to U, V, W
For drives that have a dynamic brake transistor an optional external braking resistor will need be connected to +DC and BR when
required. The Optidrive software protects the Optibrake from overload, hence no need for expensive overload relays are required (P-
34=1). The resistors have an internal fusible element to ensure fail safe operation
Two types of resistor are available for the Optidrive E2 and details are below.

For non-standard Invertek resistors, the brake resistor circuit should be protected by a suitable thermal protection circuit.

4.5. Motor Terminal Box Connections
Most general purpose motors are wound for operation on dual voltage supplies. This is indicated on the nameplate of the motor
This operational voltage is normally selected when installing the motor by selecting either STAR or DELTA connection. STAR always
gives the higher of the two voltage ratings.
Typical ratings are: STAR DELTA
400V / 230V
690V / 400V
