Specific regional regulations may allow the transformer to be mounted inside the enclosure.
In this case wire the electrical circuit to the electrical termination point inside the enclosure
and the secondary wires of the transformer to the AC Input on the controller. The earth wire
should be routed to the terminal on the controller PCB when using an internal transformer.
Termination of wiring to the controller while power is applied or the battery is
connected may cause serious damage to the controller and will VOID ALL
WARRANTEES OR GUARANTEES. Power the unit ONLY after all wiring, configuration
and jumper settings are completed.
Backup Battery
It is recommended that a minimum of a 4Ah battery is used as the main backup battery.
From the accessory bag provided, connect the RED and BLACK battery termination wires to
the B+ and B- terminals. Connect the spade terminals to the battery as shown below.
Connection of the battery in reverse will not damage the System Controller but will cause the
battery fuse (5A Fast Blow) to blow and require replacement.
Figure 5 - Battery Connection
The battery test procedure uses a special algorithm to prevent deep discharge and increase
battery endurance. A dynamic battery test is performed every ten minutes (default0) when
AC power is present and a battery condition alarm will be generated if the battery is either
disconnected or shows poor capacity. Battery fault conditions will activate the battery trouble
zone.
