1.3 Start-up Procedure
1. Configure the power supply jumpers as described in “Jumpers” on page 9.
2. Install the power supply as described in“Installation” on page 14.
3. Program the power supply as described in “Programming Options” on page 19.
4. Wire the power supply circuits, referring to the options described in“Trouble Supervision” on
page 25 and the application examples in“Applications” on page 27.
5. Connect primary power source wiring while observing the following:
– Make certain that the AC mains circuit breaker is off before making any wiring connections
between the mains and the power supply.
– Make certain primary power source is 120 VAC, 60 Hz, 3.2 amps.
– Run a pair of wires (with ground conductor) from the protected premises main breaker box
to TB1 of the power supply main circuit board.
– Use 14 AWG (1.6 mm O.D.) or heavier gauge wire with 600V insulation.
6. Apply power to the power supply using the following procedure:
– Apply AC power by turning on the AC mains circuit breaker connected to the power supply.
– Connect a properly charged battery to connector JP4 on the power supply main circuit
board.
1.4 Jumpers
1.4.1 Jumper JP1 - Ground Fault Detection
The Ground Detection circuit monitors for zero impedance between the power supply and ground.
Jumper JP1 is located in the top right section of the power supply circuit board. Cutting JP1 will
disable ground fault detection by the power supply. This should only be done if ground faults are
being monitored by a panel connected to the HPF24S power supply.
CAUTION: DISCONNECT POWER
REMOVE ALL POWER (AC & DC) BEFORE CUTTING OR MOVING ANY JUMPERS.
