Installation Manual

Overview:
The OLS180 is a power supply/charger that converts 115VAC / 60Hz input into a 12VDC or 24VDC @ 6 amps of continuous
supply current (see specifications).

Installation Instructions:
The OLS180 should be installed in accordance with The National Electrical Code and all applicable Local Regulations.
1. Mount the OLS180 in the desired location/enclosure.
2. Slide [Power ON/OFF] switch to OFF position.
3. Set the OLS180 to the desired DC output voltage via SW1 (Voltage Output Selection Table).
Keep power-limited wiring separate from non power-limited wiring (115VAC 50/60Hz Input, Battery Wires).
Minimum 0.25” spacing must be provided.
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 & Low battery supervisory
relay outputs marked [NC, C, NO].
9. Slide [Power ON/OFF] switch to ON position.
