OPERATION
⇒ Plug in the Control Panel (UPS Connector) with a male to female DB25 cable to the DB25
“Control Panel” Connector on the back of the unit.
⇒ Be sure the power cord is plugged into an appropriately rated outlet.
⇒ Activate the INPUT ON/OFF Circuit Breaker to the “ON” position on the UPS.
⇒ The AC INPUT neon indicator will illuminate.
⇒ Activate the UPS Front Panel SYSTEM ON/OFF Switch to the “ON” position. Activate the
Control Panel POWER ON switch to the “ON” position. Both switches must be “ON” to turn
on the unit.
⇒ The system will go through a diagnostic test routine.
⇒ The green AC IN OK L.E.D. will flash several times before it illuminates solid.
⇒ Green BATTERY L.E.D.s will illuminate.
⇒ The audible alarm will sound a short burst.
⇒ Push and hold in the LOAD ON/OFF Switch for at least two seconds. You can use either
Load ON/OFF Switch from the UPS or the Control Panel.
⇒ On the UPS, the AC OUTPUT L.E.D. will illuminate. On the Control Panel, you will see the
AC OUTPUT L.E.D. illuminate and the loads 1-8 will illuminate in a sequence (if Load switches
are in the “ON” position).
Switch the INPUT ON/OFF Circuit Breaker “OFF”. This will simulate a power loss to test battery
operation.
⇒ The green AC IN OK L.E.D. will flash every two to three seconds. On the Control Panel, the
ON BATT L.E.D. will illuminate and the ON AC L.E.D. will turn off.
⇒ The red ON BATT L.E.D. illuminates on the UPS.
⇒ An intermittent audible alarm will sound. (The ALARM RESET Switch may be operated at
this time, it must be held in for at least 2 seconds to silence the alarm.) If Fan Fail, Temp
Alarm or Temp Shutdown becomes active and audible alarm is silenced during DC operation,
Audible Alarm will sound again after the Fan Fail, Temp Alarm or Temp Shutdown is cleared
to indicate UPS is in DC operation.
⇒ As battery discharge continues in this condition, the five green BATTERY L.E.D.s will start to
shut off. Each led represents approximately 20% of the battery reserve available. If this
were to continue until all four L.E.D.s shut off, the last green L.E.D. will flash, indicating that a
LOW BATTERY situation is present and system shutdown is imminent. The LOW BATT
L.E.D. on the Control Panel and the UPS Front Panel will illuminate. The intermittent alarm
will become continuous at this point. The UPS will automatically shut itself off to avoid
excessive battery discharge. When power returns, normal operation of the UPS resumes
without any operator adjustment.
The duration of actual battery backup time and the LOW BATTERY condition varies depending
on the amount of load, charge on the battery, and condition of the battery. The condition of the
battery may be checked provided three conditions are satisfied:
1. AC power is present at the input of the unit.
2. AC Output is ON with at least 25% load.
3. The battery has been charged for at least 24 hours.
