Please refer to figure 6.
3.1 Start-up
3.1.1 Start-up, mains available
1 Press keypad 'I' (14, fig. 6) briefly; LED ‘on’ (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
If the mains input is absent (power cord not connected, or mains failure):
1 Press keypad 'I' until the buzzer sounds.
The LEDs 'on' and 'on battery' (13, fig. 6) will illuminate. The UPS operates on battery: it
discharges the batteries.
3.2 Use: Normal Operation
3.2.1 Normal operation conditions:
x
the mains supply is present,
x
the UPS is on,
x
the load does not exceed the capacity of the UPS and
x
the operating temperature is below alarm level
3.2.2 Load indication (fig. 5)
1 During normal operation, press keypad 'I' briefly.
2 Yellow LEDs will blink during 3 seconds, the number is load
dependent (in case of overload LED 'alarm' (9, fig. 6) blinks as well).
3.2.3 Auto-off (no-load shutdown)
If this function is activated, the UPS will switch off during a mains failure 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 default setting of the
no-load shutdown function is: activated. Changing of the setting is described in 3.4.
3.2.4 Automatic bypass switch
The UPS is equipped with an automatic bypass switch. This switch automatically transfers the
load to the mains if the UPS is unable to deliver the demanded output power due to overload or
overtemperature. The UPS will switch back to normal operation when the overload has been
removed or the temperature has dropped below alarm level.
If a power failure occurs during bypass operation, the UPS will switch to battery operation and
eventually, when the batteries are depleted, output power is lost. If the UPS functions under
overload or overtemperature conditions it may not be able to protect the load.
See also 3.3.6 and 3.4.
3.2.5 Switching off
1 Press keypad ‘0’ (15, fig. 6) for 1 second. If the UPS is switched off the output will always be
absent for a few seconds to ensure that the connected equipment is able to reboot.
2 If electric isolation is required, unplug the power cord from the wall outlet.
