Power

Caution!
Remove all power (AC and battery) before making any connections. Failure to do so might
!
result in personal injury and/or equipment damage.
Caution!
Do not short-circuit the terminals of the transformer
!
If you short the terminals, the internal fuse opens. This causes permanent failure. Connect the
transformer to the control panel AC power terminals before you plug it into the power source.
Notice!
Plan ahead
Route telephone, SDI2 bus wiring, and sensor loop wiring away from any AC conductors,
including the transformer wire. AC wiring can induce noise and low level voltage into adjacent
wiring.
Warning!
High current arcs are possible
The positive (red) battery lead and the terminal labeled 5 can create high current arcs if
!
shorted to other terminals or the enclosure. Use caution when you touch the positive lead
and the terminal labeled 5. Always disconnect the positive (red) lead from the battery before
you remove it from the terminal labeled 5.
Caution!
Battery terminals and wire are not power limited
!
Maintain a 0.250 in (6.4 mm) space between the battery terminals, battery wiring, and all
other wiring. Battery wiring cannot share the same conduit, conduit fittings, or conduit
knockouts with other wiring.
Caution!
Heavy discharges possible
!
The system can have heavy discharges if you exceed the maximum output ratings or install
the transformer in an outlet that is routinely switched off. Routine heavy discharges can lead
to premature battery failure.
Notice!
Use sealed lead acid batteries only
The charging circuit is calibrated for lead-acid batteries. Do not use gel-cell or NiCad
batteries.
