b. Connection with three-phase input
Note: If using three-phase mains connection, make sure
the phase sequence is correct. The UPS cannot start up if
the phase sequence is wrong, and an alarm will sound. At
the same time, "Phase sequence error" appears on the LC
display. Make sure the neutral conductor is connected
correctly as well.
5. Installation clearances
A gap of at least 80 cm is required in front of the
PROTECT 1.M and at least 30 cm behind the UPS for
maintenance purposes. No objects should be placed
closer than 30 cm to the side of the UPS.
