Installation Manual
Overview:
The OLS180220 is a power supply/charger that converts 220VAC (working range 198VAC-256VAC), 50/60Hz input into
a 12VDC or 24VDC @ 6A of continuous supply current (see specifications).

Output VDC Switch Position Max. Load DC
12VDC SW 1 - ON 6A
24VDC SW1 - OFF 6A
Installation Instructions:
The OLS180220 should be installed in accordance with The National Electrical Code and all applicable Local Regulations.
1. Mount the OLS180220 in the desired location/enclosure.
2. Slide [Power ON/OFF] switch to OFF position.
3. Set the OLS180220 to the desired DC output voltage via SW1 (Voltage Output Selection Table).
CAUTION: Do not touch exposed metal parts. Shut branch circuit power before installing or servicing equipment.
There are no user serviceable parts inside. Refer installation and servicing to qualified service personnel.
4. Connect AC power to the terminals marked [L & N], connect ground to the terminal marked [G].
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).
5. Measure output voltage before connecting devices. This helps avoiding potential damage.
6. Connect devices to be powered to the terminals marked [– DC + ].
7. When the use of stand-by batteries is desired, 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.
Note: When batteries are not used, a loss of AC will result in the loss of output voltage.
8. Connect appropriate signaling notification devices to AC Fail and Low Battery supervisory relay outputs
marked [NC, C, NO].
9. Slide [Power ON/OFF] switch to ON position.
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 Loss of AC. Discharged or no stand-by battery. No DC output.
