7.4 SWITCHING ONTO MANUAL BYPASS.
Switching onto the manual bypass creates a direct connection between the UPS input and output, completely
excluding the equipment control part. This operation is performed in the event of ordinary maintenance on the
equipment, so as not to remove the power supply from the load, or in the event of a serious failure while waiting
for the equipment to be repaired.

7.6 EMERGENCY SHUTDOWN (E.S.D.).
Should it be necessary to interrupt the continuous power supply provided by the UPS quickly (emergency shut-
down), this can be done by putting switch
Q3
to position
0
or, where applicable, by activating the emergency
button/switch connected to the
ADC card
.
The UPS output can only be electrically disconnected by means of Q3.
If the UPS is operating from the manual bypass (Q5 in position 1) with mains present, the emer-
gency shutdown does not interrupt the power supply to the load. In emergency conditions all the
power supplies upstream of the UPS must be disconnected.
