3 - OPERATION

3.1 Start-up

3.1.1 Start-up, mains available

1 Press keypad 'ON' for 2 seconds
LED 'LINE' (already blinking) will illuminate continuously now.
2 The equipment connected to the UPS can now be switched on.

3.1.2 Start-up, mains not available ('battery start')

If the mains input is absent (power cord not connected, or mains failure):
1 Press keypad 'ON' for 2 seconds until LED 'BAT' illuminates.
The UPS operates on battery: it discharges the batteries.

3.2 Use: Normal Operation

3.2.1 Normal operation conditions:
• the mains supply is present,
• the UPS is on,
• the load does not exceed the capacity of the UPS and
• the operating temperature is below alarm level.
AVR (Automatic Voltage Regulation):
If the quality of the incoming mains is poor, the AVR boosts a low incoming voltage or reduces a
high one. The load receives a voltage within the normal range (see chapter 7).
3.2.2 Self test (UPS operation and battery condition)
In case of a system failure the output voltage can be lost. It is therefore recommended to switch
off the load before performing a self test. See chapter 6.
1 During normal operation, press keypad 'ON' for 2 seconds.
2 If the battery does not pass the self test, a 'replace battery' alarm is given. See 3.3.

3.2.3 Auto-off (no-load shutdown)

When mains is not available (mains failure or battery start) the UPS will switch off when the load
is less than 5% of the maximum load. In this way unnecessary discharging of the batteries is
avoided. The unit will automatically turn on again when mains power is restored. The no-load
shutdown function cannot be de-activated.

3.2.4 Switching off

1 Press keypad 'OFF' for 2 seconds.
2 If electric isolation is required, unplug the power cord from the wall outlet.
