Wiring
MEV UNIT
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 the supplied boost
switch or 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.
