3.10.3Connecting the mains voltage

The appliance is supplied without a power cable and isolator.

Note

In order to receive electrical power, the appliance has to be connected to the mains power by means of a permanent electrical connection. A double-pole isolator with a contact gap of at least 3 mm must be fitted between this permanent connection and the appliance. The power cable must have cores of at least 3 x 1.0 mm2.

Warning

Leave the appliance isolated until you are ready to start it up.

1.Connect phase (L), neutral (N) and earth () of the power cable to terminals 22 through 24 of the connection block as indicated in the

table (3.10.2 "Preparation").

2.Fit the power cable in the strain relief.

3.Connect the power cable to the isolator.

4.If you have no more connections to make:

-Fit the cap on the electrical terminal block.

-Fit the plastic covers onto the appliance.

3.10.4Isolating transformer

An isolating transformer should be used if there is a case of 'floating neutral'.

1.Refer to fitting instructions provided with the isolating transformer. (Contact the supplier for details of the correct isolating transformer.)

2.Connect phase (L), neutral (N) and earth () to terminals 16 through 21 of the terminal block as stated in the table (3.10.2 "Preparation").

3.Fit the cables in the strain relief.
