faster and after a few seconds it will illuminate continuously, indicating that the unit has
started up.

4.3 Use: normal operation

4.3.1 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
•
4.3.2 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.
The setting can be changed using the UPS monitoring software. For more information please refer to
the manual that came with the software.
If the no-load shutdown function is activated and the load is smaller than the 5% threshold, the '25%'
load LED will blink to warn you that the unit will switch off during a mains failure.
4.3.3 Switching off
During normal operation, via operating panel:
1 Press keypad '0' (2, fig. 4.1) 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.
During normal operation, using UPS monitoring software:
1 Shutdown after delay, see 4.4.10.
During bypass operation: see section 4.4.3.
During battery operation: see section 4.4.4.
If electric isolation is required, unplug the power cord from the wall outlet.
