3. Connect AC power to terminals marked [L & N], connect ground to terminal marked [G] (if used).
Use 18 AWG or larger for all power connections (Battery, DC output).
Use 22 AWG to 18 AWG for power limited circuits (AC Fail/Low Battery reporting).
4. Measure output voltage before connecting devices. This helps avoid potential damage.
5. Connect devices to be powered:
a. For Power Supply Board connect to terminals marked [– DC +].
b. For Power Distribution Module(s) connect devices to be powered to terminal pairs 1 to 4 marked
[1P & 1N thru 4P & 4N] (Fig. 2, pg. 3), 1 to 8 marked [1P & 1N thru 8P & 8N] (Fig. 3, pg. 3), or 1 to 16 marked
[1P & 1N thru 16P & 16N] (Fig. 4, 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 terminals marked [– BAT +]
(battery leads included). Use two (2) 12VDC batteries connected in series for 24VDC operation.
Note: When batteries are not used a loss of AC will result in the loss of output voltage.
For supervised models only:
7. Connect appropriate signaling notification devices to AC Fail & Low Bat supervisory relay outputs
marked [NC, C, NO] (Fig. 1a, pg. 3).
