-
Slide [Power ON/OFF] switch to OFF position (Fig. 1, pg. 2).
-
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, AC input).
Use 22 AWG to 18 AWG for power limited circuits (AC Fail/Low Battery reporting).
Keep power-limited wiring separate from non power-limited wiring (220VAC, 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. -
Slide [Power ON/OFF] switch to ON position (Fig. 1, pg. 2).
-
Measure output voltage before connecting devices. This helps avoiding potential damage.
-
Slide [Power ON/OFF] switch to OFF position (Fig. 1, pg. 2).
-
Connect devices to be powered to the terminals marked [– DC +].
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).
Note: When batteries are not used, a loss of AC will result in the loss of output voltage. -
Connect appropriate signaling notification devices to AC Fail & Low battery supervisory relay outputs marked [NC, C, NO].
-
Slide [Power ON/OFF] switch to ON position (Fig. 1, pg. 2).
