INSTALLATION
2. Then connect the other end of the cable to the battery connector at the back of the UPS.
3. To add further battery boxes (up to a total maximum capacity of 120Ah), repeat the previous steps.
Note: When a battery box is installed, the UPS must be configured for the correct total capacity of the batteries
(using UPSTools software) in order to calculate correctly the remaining back-up time and the battery charge. The
configuration must be done with the UPS switched on or in stand-by mode.
For this kind of battery box the value to be added is “9”[Ah].
For the DVD 220/300 models whose total battery capacity has not been increased, the recharge current is 2 A.
After setting the nominal battery capacity with the UPSTools software, if the value set is greater than 14 Ah, the
recharge current automatically increases to 6 A.
START-UP/SHUTDOWN
To start up and shut down the UPS, press the ON and OFF switch for at least three seconds.
Starting up for the first time: after about 30 seconds, check that the UPS is working properly:
1. Simulate a mains power supply failure by unplugging the input power cable
2. The load must continue to receive power, the battery mode indicator should light up and the UPS
should beep every 4 seconds.
3. Reconnect the power cable. Normal mains power operation should be restored.
START-UP FROM BATTERY
The UPS can be switched on even when no mains power supply is available and the battery is fully charged.
Just press ON for at least three seconds to start the UPS.
RECHARGING
The UPS is supplied with fully charged batteries. During shipping, however, they can lose some of their charge
and so the batteries must be recharged before use. Connect the UPS to the mains power supply and leave the
UPS to recharge for at least 8 hours before discharging it.
