The main illustration above is based on the

0.75kW rating (size 1). The supply terminals for ratings from 1.1kW (size 2) is also shown. The L3/T terminal (if present) can be ignored. The order of the three motor phases determines the initial direction the motor turns.

2. Power and Motor Connections (Three Phase)

Before commencing, confirm that the Inverter and all cables are completely isolated from the power supply, have been isolated for at least 5 minutes and that the motor is not turning.

The illustration on the left is based on the 22kW 400V model. The terminal layout for other ratings is similar.

The order of the three supply phases is not important. They should be connected to the terminals marked L1/R, L2/S and L3/T as shown. In some cases, these terminals may be marked L1, L2 and L3 only.

The order of the three motor phases determines the initial direction the motor turns. This can be reversed by physically swapping any two motor phases. Or by changing the Inverter parameters.

Use screened or armoured cable between the Inverter and Motor. To minimise electromagnetic interference, ensure the cable screen is grounded as shown.

The motor must be separately earthed.

3. Motor Connections - Star and Delta

Dual voltage induction motors typically include terminal boxes with six points. The points can be connected together with links in one of two ways to suit one of the two rated voltages.

The two ways of connecting the links are shown below. These are known as “Star” (the higher voltage) or “Delta” (the lower voltage).

Link

Phase

STAR

The selection of Star or Delta is not optional and must match the supply voltage.

Dual voltage motor nameplates include symbols to represent voltage and full load current in each configuration. Delta is represented by a triangle and star by a Y (Wye).

3.1 Motor connected in STAR (or Wye):

For safety purposes, Star (shown opposite) is the default configuration for small motors (usually to 3kW) and is sometimes known as “two at one side”.

Only two links are required for Star. Double-up the links if changing from Delta to allow the motor to be changed back in future.

The order of the three phases determines the direction the motor turns.

Note that the manufacturer recommends that the cable screen is earthed at both ends and the motor and Inverter are earthed separately.

3.2 Motor connected in DELTA:

The link configuration is shown in the illustration opposite and is sometimes referred to as “three-a-breast”.

The order of the three phases determines the direction the motor turns.

Note that the manufacturer recommends that the cable screen is earthed at both ends and the motor and Inverter are earthed separately.
