INSTALLATION
Upon receipt of the digital regulator, perform a visual inspection to ensure that no damage has been
sustained 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 M4x25 screws and
must be installed in a location where the temperature does not exceed the environmental conditions
foreseen. Refer to the attached drawings for dimensions and displacement.
