R.E.P.O.

This isolated input is used to turn off the CPS remotely in case of emergency.
This CPS is provided from the factory with "Remote Emergency Power Off" (R.E.P.O.) terminals short-circuited (see "Views of
the CPS connections"). If it is to be installed, remove the short-circuit and connect to the normally closed contact of the
stopping device by using a cable that ensures a double isolation connection.
In case of emergency, the R.E.P.O.control is opened by activating the stopping device; the CPS 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. Therefore, no external power supply voltage is required. When
closed (normal condition) a maximum current is present.
S
YSTEM TESTS
The CPS is equipped with a device able to simulate a fault in the power supply; this allows to carry out periodical tests on the
efficiency of the entire system. The test can be carried out manually or automatically by setting the configuration software.
E S
XTERNAL YNC
This non-isolated input can be used to synchronise the inverter output with an opportune signal coming from an external source.
If it is to be installed it is necessary to:
Use an isolation transformer with an isolated single-phase output (SELV) within the range 12÷24Vac with a power 
➢
0.5VA
➢ Connect the transformer secondary to the "EXTERNAL SYNC" terminal (see "Views of the CPS connections") using a
double isolation cable with a 1mm2 cross section. Warning: always respect the polarisation as in the figure below:
After installation, enable the control using the configuration software.
