Electrical connection

This heater must only be connected to a three phase supply. The supply voltage must correspond to the voltage shown on the heaters rating label.

IMPORTANT : The wires in this mains lead are coloured in accordance with the following code :

BROWN	-	LIVE (L1)
BLACK	-	LIVE (L2)
GREY	-	LIVE (L3)
BLUE	-	NEUTRAL
GREEN & YELLOW	-	EARTH

Note : ‘L’ or ‘N’ must not be connected to the EARTH terminal marked ‘E’

or or coloured GREEN or GREEN AND YELLOW.

If in doubt, consult your electrician.

Star / Delta Voltage Systems

The heater is wired to accept 380-415V ~3PN (see Fig. 5b).

To change to a 220-240V ~3P system (see Fig. 5a) the following steps should be carried out :

1.Swap the plug on the end of the Mains In lead to a 4 Pin plug (refer to * in table above for plug loading).

BROWN	: LIVE (L1)
BLACK	: LIVE (L2)
GREY	: LIVE (L3)
BLUE	: Insulate exposed core and place
	inside plug housing.
GREEN & YELLOW	: EARTH

2.Remove the control moulding and top panel.

3.Change over the links on the Star / Delta Terminal Block to resemble Fig. 5a.

4.Remove the blue neutral wire from ‘N’ and connect into ‘L3’ in the Mains In Terminal block.

5.Replace the control moulding and top panel.

Attention: If using an extension cable, ensure that it complies with local electrical regulations and is suitable for the loads shown above.
