Wire to internal in/out terminal block.
Be certain UPS ON/OFF switch is OFF.
Install the supplied battery fuse.
III. OPERATING INSTRUCTIONS:
NORMAL:
Open external door only.
Engage 250VDC buss at external switch/fuse box.
Verify that “250VDC BUSS” lamp is lit.
Engage on/off switch to ON.
Verify that “CONVERTER POWER” and “INVERTER POWER” lamps are lit.
Engage alert switch to ON.
Verify battery float voltage to spec.
Close door using all door clamps.
250VDC BUSS FAILURE:
If this condition continues beyond a need for UPS power, disengage the
internal switch until such time when the buss is stable. This will conserve
the battery for a more rapid recharge and readiness for the next outage.
If this is not done the UPS will automatically shut down when the battery
is depleted.
In this state, either the external switch or the internal one must be
toggled OFF and then ON to reset the UPS.
After an outage, it is a good practice to view the status indicators as
above under “NORMAL” operation.
