Connecting the Battery to the PCB. See Diagram 3.
1. Place the battery into position. If required, fit the optional Battery retaining bracket by inserting the tab at the Left Hand end
of the bracket into the slot provided near the Mains Transformer. Insert the tab at the Right Hand end of the bracket into the
other slot by gently pushing inwards and down on the side of the bracket.
2. Connect the supplied Battery Cable between the “+” and “0V” connections of “TB3” on the PCB (C) and the Battery
terminals (D), observing correct polarity.
Fitting the Cover.
In order to comply with regulations, the cover must be fitted and the screw provided to fix the cover to the chassis must be
tightly secured.
Power Supply connection details. (Refer to diagrams on page 4)
Links:
JP2
No longer fitted.
(If this Link is fitted [ie on an older board] a LOW state on the “PSDOWN” input will enable the Power Supply)
R20
R20 can be cut out of the PCB to reduce the current limit to 1.0 Amp.
Connectors:
TB1
16.5V 2.5A AC Transformer input connections.
TB2
13.8V DC Output, alarm outputs and control input.
See page 4 for details..
