MAINS CONNECTIONS
Do not connect the mains supply to the panel
until you are fully conversant with the layout
and features of the equipment.
A rating plate is attached to the power supply
module describing the nature of the supply
permitted.
The incoming mains supply should be brought
into the panel via one of the knockouts
provided.
A suitable cable gland must be used to secure
the outer sheath of the cable used. The earth
must first be connected to the primary earth
stud (peg) marked with a
symbol, using
the ring crimp provided.
Sufficient earth lead should be left to allow Live and Neutral connections to be accidentally pulled from the
terminal block while leaving the earth connection intact.
CONNECTING THE BATTERIES
Batteries of even very small capacity are capable of delivering very high currents which can cause fire or
injury, therefore battery connections should be done with caution.
The panel is supplied with battery leads already connected to the battery terminals on the main PCB.
These leads are coloured red for +ve and black for -ve.
2 x 12v batteries should be connected in series
using the white jumper lead provided. See
diagram.
To optimise the service life of the batteries, the
battery charger output voltage varies with
temperature.
N.B.
In the event of mains failure, the battery charger
circuit will protect the batteries from full discharge
by disconnecting them when they reach below
19v. When the mains supply is restored the
batteries will be automatically reconnected.
NOTE:
If the mains is connected before the batteries, the panel will show a Power Supply fault for up to 1 minute
until the monitoring cylce has finished polling. This is normal. If the fault
doesn’t clear after 1 minute, check
connections.
