R.E.P.O.

This isolated input is used to turn off the CPS remotely in case of emergency.
The CPS is supplied from the factory with the "Remote Emergency Power Off" (R.E.P.O.) terminals short-circuited (see
"View of CPS 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 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. No external power supply voltage is therefore required.
When it is closed (normal condition), a maximum current of 15mA is present.

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.

XTERNAL YNC
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 CPS connections" ref.19)
using a double isolation cable with a 1mm
below.
After installation, enable the control using the configuration software.
