4.5 Changing the Wiring
This furnace is wired internally in such a way that it can be altered to suit the
customer's supply voltage. The following supply voltages are permissible:
1) 3-phase star configuration with neutral in the range 380/220 volts to
415/240 volts.
2) 3-phase delta configuration without neutral in the range 208 to 240
volts.
3) Single phase in the range 208 to 240 volts.
Any wiring alterations required must be made between the Supply Terminals
and the Fuses. To access the Supply Terminals and Fuses, remove the panel
adjacent to the cable entry point. Disconnect the link wires and reconnect as
required as shown in Figs 6 to 8.
