Fire resisting
3-core cable
(Between 1 mm² and 2.5mm²) or a suitable 3-conductor system, fed from an isolating
double pole switch fused spur, fused at 3A.
IT SHOULD NOT BE CONNECTED
THROUGH AN RCD.
This should be secure from unauthorised operation and be

Connecting the batteries
The Premier EX8 requires 2 x 12 V sealed lead acid (SLA) batteries
The two batteries are wired in
series
.
The
+ve
of one battery is connected to the
red
battery lead.
The
–ve
of the other battery is connected to the
black
battery lead.
The –ve of the first battery is connected to the +ve of the second battery using the
link wire supplied.
Although there are many sizes of suitable battery, the enclosure has been designed
for 12V 7Ah or 12V 12Ah. Use the battery calculation information later in this manual
to work out the required stand by battery size.
Charger Short Circuit Protection
The Premier EX8 has an intelligent charger that senses if too much current is being
drawn (for instance in the case of totally discharged batteries, or the charger leads
being shorted together). In such an event, the Premier EX8 4-8 zone panel will turn
off the power to its charger circuit.
The panel also turns off the charger when the batteries are disconnected.
