R.E.P.O.
This isolated input can be used to remotely switch off the UPS in case of emergency.
The UPS is supplied with "Remote Emergency Power Off" (R.E.P.O.) terminals short-circuited by a jumper (see "
Front UPS
Views
"). To manage emergency shutdown, replace the jumper with the selected normally closed stop device contact. Connect
using double insulation wiring.
In case of an emergency, the stop device opens the R.E.P.O. control and the UPS goes into stand-by mode (all power stages
off) and the load is completely disconnected.
The R.E.P.O. circuit is self-powered with SELV circuits. Therefore, an external voltage supply is not required. When closed
(normal condition), a current of 15mA max circulates.

This non-isolated input is used to synchronize the inverter output with a suitable signal coming from an external source.
To install:
use an isolation transformer with isolated single-phase output (SELV) within range 12-24V AC with
0.5VA power
connect the transformer primary to the external synchronization source, respecting the polarity indicated in the
following image
connect the transformer secondary to terminals
A1-
A2 “EXTERNAL SYNC"
(see
"UPS connections view"
) by means
of a double insulation cable with 1 mm2 section. Attention: respect polarisation as indicated in the following image:
A special optional kit is available for external synchronization connection.
After installation, enable this option by means of the configuration software.
