Installation Instructions
-
Mount AL624 in the desired location/enclosure (mounting hardware included).
-
Unit is factory set for 12VDC. For 6VDC output cut jumper J2, for 24VDC output cut Jumper J1.
-
Connect proper transformer to the terminals marked [AC] (refer to Voltage Output/Transformer Selection Table).
Use 18 AWG or larger for all power connections (Battery, DC output). -
Measure output voltage before connecting devices. This helps avoiding potential damage.
-
Connect devices to be powered to the terminals marked [+ DC] and [DC – BAT], carefully observing polarity.
-
Connect battery to the terminals marked [BAT +] and [DC – NEG] (battery leads included)
Note: To avoid damage connect batteries as follows:- For 6VDC operation connect one (1) 6VDC battery.
- For 12VDC operation connect one (1) 12VDC battery or two (2) 6VDC batteries wired in series.
- For 24VDC operation connect two (2) 12VDC batteries wired in series.
Note: When batteries are not used, a loss of AC will result in a loss of output voltage.
LED Diagnostics
| Red (DC) | Green (AC) | Power Supply Status |
|---|---|---|
| ON | ON | Normal operating condition. |
| ON | OFF | Loss of AC. Stand-by battery supplying power. |
| OFF | ON | No DC output. Short circuit or thermal overload condition. |
| OFF | OFF | No DC output. Loss of AC. Discharged or no battery present. |
