[1P & 1N] through [8P & 8N] on PD8/CB (Fig. 2, pg. 2) or terminal pairs 1 to 16 marked
[1P & 1N] through [16P & 16N] on PD16W/CB (Fig. 3, pg. 3), carefully observing correct polarity.
*Note: Power switch is used to disconnect the L (HOT) terminal from the rest of the board.
When servicing the unit, AC mains should be removed.
6. When using stand-by batteries, they must be lead acid or gel type. Connect battery to the terminals marked [– BAT +]
(battery leads included). Use two (2) 12VDC batteries connected in series for 24VDC operation (Fig. 4, pg. 3).
Note: When batteries are not used, a loss of AC will result in the loss of output voltage.
7. Connect appropriate signaling notification devices to the AC Fail & Low Bat supervisory relay outputs
marked [NC, C, NO] (supervised models only) (Fig. 4a, pg. 3).

Terminal Legend Function/Description
L, G, N Connect 115VAC to these terminals: L to Hot, N to Neutral.
--- DC + 12VDC / 24VDC @ 6 amp continuous output.
AC FAIL
NC, C, NO
Used to notify loss of AC power, e.g. connect to audible device or alarm panel. Relay normally
energized when AC power is present. Contact rating 1 amp @ 120VAC / 28VDC.
Low Battery
NC, C, NO
Used to indicate low battery condition, e.g. connect to alarm panel. Relay normally energized
when DC power is present. Contact rating 1 amp @ 120VAC / 28VDC.
Low battery threshold:
12VDC output threshold set @ approximately 10.5VDC,
24VDC output threshold set @ approximately 21VDC.
--- BAT + Stand-by battery connections. Maximum charge rate 0.7 amp.
