User's Guide Revision 1
The UPS shall check its internal functions, synchronise to bypass and start to supply the load. The
green LED is blinking if there occurs an active notice. In normal operation the green LED is constantly
lit if no new active notice such as ‘unsynchronised’ or similar notices present.
The output voltage shall be verified from the output measurements screen of the LCD. If there is
voltage in the output then UPS is supplying the load.
