PRESENTATION
The Hot Swap kit allows you to create a UPS isolation system without interrupting the power supply to the load thanks to the
use of the plug-socket kit and a control peripheral panel (made by the installer).
COMMISSIONING
REPLACING THE UPS IN /OUT TERMINAL COVER
ALL OPERATIONS DESCRIBED IN THIS SECTION MUST BE PERFORMED BY QUALIFIED
PERSONNEL ONLY. Our Company assumes no liability for damages caused by incorrect connections
or operations not contained in this manual.
The UPS has HAZARDOUS electrical voltages inside it, even when the input and/or battery switches
are off. The inside of the UPS is protected by safety panels which should not be removed by untrained
personnel. All installation and maintenance or operations involving access inside the UPS require the
use of tools and may ONLY be performed by trained personnel.
To carry out the following operations, the UPS must be disconnected from the mains power supply,
switched off, and with all the equipment switches and fuse holders open.
Remove the terminal cover by removing the securing
screws as shown in the figure.
Remove any existing connections from the terminals.
NOTE: To remove the cables, insert a flat screwdriver in
the slot of the clamp located above the cable entry.
Removal example (Model 5-6 kVA)
Fit the newly supplied terminal cover complete with socket
as shown in the figure

INSTALLATION
ATTENTION: the installation must be performed by qualified personnel only.
Example image
(distribution panel for single phase installation)
NOTE 1: The SWIN and SWOUT switches are not mandatory but
recommended, as the wiring connector is protected from direct
contact.
NOTE 2: It is suggested that the mains cable enter from the upper side
of the panel. Fitthe cables to exit towards the UPSand the load
on the lower side of the panel.
NOTE 3: Upstream of the distribution panel input line, install the
protection device prescribed in the UPS user manual.
NOTE 4: For sizing of the minimum section of the cables, refer to the
UPS user manual.
NOTE 5: The switches used must have a current capacity greater than
the nominal current of the UPS connected.

WARNING: it is essential that terminals SW_BYP of the UPS are connected to the auxiliary contact of
the SERVICE BYPASS switch. When the SERVICE BYPASS switch closes, this auxiliary contact opens,
indicating to the UPS that the SERVICE BYPASS has been inserted. If this connection is not present, power
to the load may be cut off and the UPS may be damaged.
A WARNING LABEL MUST BE AFFIXED ON ALL MAINS POWER DISCONNECTING SWITCHES NOT
INSTALLED NEAR THE UPS AREA, TO REMIND SERVICE PERSONNEL OF THE FACT THAT THE
CIRCUIT IS CONNECTED TO A UPS. THE LABEL MUST CARRY THE FOLLOWING WORDING:
