WIRING
The local isolator must be connected to the mains as
part of the fixed wiring. Connect the cores of the power
cable to the matching terminals on the local isolator
(3A fuse spur or similar).
The black switch live core of the mains cable can be
wired to a switch input such as a light switch. When
the switch is turned on, the boost function is engaged.
When the switch is turned off, the unit will return to
normal running mode. In this configuration a triple pole
isolator must be used.
