II.
Connect Line 1 (L1) to U1, Line 2 (L2) to V1 and Line 3 (L3) to W1.
III.
Connect the Earth wire to the separate terminal supplied.
IV.
Turn on the power supply and check the direction of rotation.
V.
If the direction of rotation is incorrect, swap over any two of the “line - in” wires. For example, Line 1

C.3 Star-Delta
Connection
Procedure
If the motor is to be used with a Star-Delta starter, then the motor is only to be used with a mains supply
which is equal to the Delta voltage as shown on the rating plate. In this case the metallic connection strips
inside the terminal box have to be removed before the motor is connected; the Star and Delta connection
will be made successively in the starter as the motor is started and approaches its operating speed/power
output. Please refer to the wiring diagrams sent with the motor for wiring connections.
