INSTALLATION
Upon receipt of the digital regulator, perform a visual inspection to ensure that no damage has been su-
stained during transportation and movement of the equipment. In the event of damage, advise the shipper,
the insurance company, the seller or Mecc Alte immediately. If the regulator is not installed immediately,
store it in its original packaging in a dust and humidity-free environment.
The regulator is normally installed in the generator terminal box. It is fixed with two M4x20 or M4x25
screws and must be installed in a location where the temperature does not exceed the environmental con-
ditions foreseen.
