EMOTE MERGENCY
This isolated input is used to turn off the UPS remotely in case of emergency.
The UPS is supplied from the factory with the "Remote Emergency Power Off" (R.E.P.O.) terminals short-circuited (see "View
of the UPS connections"). If it is to be installed, remove the short-circuit and connect to the normally closed contact of the stop
device using a cable that provides a double isolation connection.
In case of emergency, by activating the stop device, the R.E.P.O. control is opened and the UPS enters stand-by mode (see
"USE" section), and powers off the load completely.
The R.E.P.O. circuit is self-powered with SELV type circuits. No external power supply voltage is therefore required. When it is
closed (normal condition), a maximum current of 15mA is present.

This non-isolated input is used to synchronise the inverter output with an appropriate signal coming from an external source.
For the installation:
Ø use an isolation transformer with an isolated single-phase output (SELV) comprised in the range 12-24Vac with ≥
0.5VA power
Ø
connect the transformer secondary to the "EXTERNAL SYNC" terminal (see "View of UPS connections", point 4)

using a double isolation cable with a 1mm cross-section. Make sure to respect the polarisation as in the figure below.
After installation, activate the command using the advanced configuration software UPSTools provided on the CD-ROM shipped
with the UPS system.

ONNECTION OF THE REMOTE MAINTENANCE BYPASS
An additional maintenance bypass can be installed on a peripheral electric control panel, for example to replace the UPS
without interrupting power to the load.
It is essential to connect the SERVICE BYPASS terminal (see "View of UPS connections", point 2) to the
auxiliary contact of the SERVICE BYPASS switch. Closing the SERVICE BYPASS switch (4), will open this
auxiliary contact which signals the insertion of the maintenance bypass to the UPS. Absence of this
connection could interrupt the power to the load and cause damage to the UPS.
NOTE: use cables with a cross-section compliant with the indications given in the "Cable Sizes" section.
2
Use 1mm cables with double isolation to connect the SERVICE BYPASS terminal to the auxiliary contact of the
remote maintenance bypass disconnecting switch.
If the UPS is fitted with an internal isolation transformer, ensure compatibility between the remote
maintenance bypass and the neutral arrangements.
