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.
• Activate the procedure COMMANDS > IMMEDIATE COMMANDS > BYPASS PROCEDURE;
• Carry out the operations indicated on the mimic panel.
7.5 RETURN TO NORMAL MODE.
• Put switch Q2 into position 1 (mains ON);
• Wait for the mimic panel to switch on;
• Activate the procedure COMMANDS > IMMEDIATE COMMANDS > START PROCEDURE;
• Carry out the operations indicated on the mimic panel.
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.
