3.4.5 Fault output contact connections
A volt free contact rated at 30V DC and 1 Amp is available
for connection to other systems.
This contact will operate upon any of the fault conditions
listed in section 4.
The contact positions shown here are with mains
and battery connected and with no fault conditions
on the power supply.
3.4.6 Battery Connections
Batteries of even very small capacity are capable of
delivering very high currents which can cause fire or
injury. Battery connections must therefore be made using
extreme caution
.
As supplied, power supplies have battery leads already
wired to the battery terminals on the circuit board. These
leads are coloured red for + and black for – and are fitted
with standard ¼ inch push on, spade connectors suitable
for batteries of up to 12Ah capacity.
Larger capacity batteries have screw on terminals and the
standard battery leads will need to be replaced with the
ones supplied in the accessory pack. Take care that the
red and black wires are connected to the correct terminals when replacing battery leads, a wrong connection can be
dangerous and can cause damage.
As this is a 24-Volt system, there will be two 12 volt batteries which need to be connected in series. This is done using
the jumper link provided.
To optimise the service life of the batteries, the battery charger output voltage varies with temperature. To enable
optimum temperature compensation, the flying lead temperature sensor should be attached to one of the batteries as
shown in the diagram in section 9 of this manual.
