The motorised changeover switches automatically manage changeover under load between two three-
phase power supplies, or manually for emergency operations.
These devices are suitable for low voltage systems with interruption of the supply to the load during
transfer.
The model supplied in the automatic version checks the source and switches over automatically, based
on configurable parameters.
OPEN TRANSITION TYPE TRANSFER SWITCH WITH A MINIMUM INTERRUPTION OF THE
SUPPLY DURING TRANSFER.
To maintain the microprocessor powered and avoid its restarts it is suggested the "P091 Back-
up module controller" optional accessory. The back-up module guarantees the microprocessor
power supply for a few minutes, in case of supply voltage failure.
The remote condenser must be powered by the automatic transfer switch.
It is suggested the optional "P191 power supply for condenser" from the indoor machine electrical board.
The optional includes magnetothermic switches for condenser fans.
