With the UPS operating in online mode (synoptic shown in Fig. 54),
proceed as follows to shut it down completely:
Stop the loads (or set their switches on the distribution
1.
board to "Off", if any) progressively.
Switch the unit to bypass as described in the previous
2.
section 6.1.5.
Set the switch corresponding to the UPS output on the
3.
control panel (external) to "Off".
Set the output switch of the UPS to "Off" (Q2) (only for
4.
tower format devices).
Units with external batteries: Disconnect the battery

cable between the unit and the battery cabinet. Set the
external battery cabinet switch or disconnect switch to
"OFF" (F8).
Set the switch corresponding to the UPS input on the

control panel (external) to "Off".
pass line for the UPS, also set this switch on the control panel
to "Off".
At this point, the unit will stop completely

If possible, cut off the general power supply to the con-

trol panel.
Set the input switch of the UPS to "Off" (Q1) (only for
8.
tower format devices).
Set the bypass switch to "Off" (Q4) (only for tower format
9.
devices).
The UPS is now completely stopped and there is no voltage at its
input, bypass and output terminals.
However, perform the relevant checks using external
measuring instruments before carrying out any work
to disconnect the cables.
DANGER OF ELECTRIC SHOCK: before any repair or
maintenance operation inside the unit, to be carried
out solely and exclusively by the qualified Technical Ser-
vice, wait for approximately 5 minutes from this moment,
the required time for the electrolytic capacitors to dis-
charge.
For units with internal batteries, disconnect and isolate the
positive, neutral and negative battery terminals.
6.3. MANUAL OR MAINTENANCE BYPASS.
When a repair or maintenance intervention on the UPS is neces-
sary, to be carried out by the qualified Technical Service, and the
continuity of supply to the loads must be maintained, the output
must be transferred to the bypass line via the maintenance by-
pass switch (Q5), integrated in the unit or optionally in the ex-
ternal control panel (with the auxiliary contact correctly wired to
the UPS interface terminals, (EMBS)).

6.3.1. Transferring to maintenance bypass mode.
To detail this procedure, we will start from the initial point of the
UPS operating in normal mode (rectifier converters, charger and
inverter running; output in inverter). If it is necessary to transfer to
maintenance bypass from another status (from bypass mode, for
example, either by manual transfer or by unit alarm), carry out the
same steps, for greater safety.
Do not actuate the manual bypass switch (of the unit
or on the external control panel) directly in normal
mode, or in general, without strictly following the procedure
described here. The "uncontrolled" operation of this mecha-
nism may cause faults on the unit and/or damage to the in-
stallation.
To switch to maintenance bypass mode:
Switch the unit to bypass as described in the previous
1.
section 6.1.5.
The loads switch to being supplied directly from the
2.
static bypass line. Check that the unit's synoptic corresponds
to the one in Fig. 56 (unit in bypass mode).
