R.E.P.O.
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
UPS connections” ref.15). 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:
use an isolation transformer with an isolated single-phase output (SELV) comprised in the range 12-24Vac with
0.5VA power
connect the transformer secondary to the "EXTERNAL SYNC" terminal
(see "View of UPS connections” ref.19) using a
double isolation cable with a 1mm

cross-section. Make sure to respect the polarisation as in the figure below.
After installation, enable the control using the configuration software.
