Caution: Do NOT connect the battery backwards; charger damage may result
The voltmeter will show battery voltage as soon as the DC connection is completed.
Check the voltmeter
as soon as the DC connection has been made.
If the meter reads zero or is deflecting below zero, reverse
the polarity of the battery connections.

Form C contact
Connect to the charger’s Form C contacts according to Figure 2.3
1. Make connections to the system's Form C alarm contacts as shown.
2. Run alarm wiring out of the charger separately from the AC supply wiring
3. Use 16 to 22-gauge wire.
4. NOTE: Do not exceed the relay maximum current rating of 0.5A @ 117 VAC or 1A @ 24 VDC.
The remote alarm connection board is located on the circuit breaker pan, adjacent to the control board.

Temperature Compensation
F3 chargers include battery temperature compensation (TC). TC is required by all batteries for maximum
performance and life. The TC feature automatically reduces the charger’s output voltage at high
temperatures and vice-versa.
