DSR DIGITAL REGULATOR
INSTALLATION
Upon receipt of the digital regulator, perform a visual inspection to ensure that no damage has been sustained during transporta-
tion 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 conditions foreseen.
CONNECTIONS
The digital regulator connections depend on the application and excitation system. An error in connection may have serious
consequences for the unit. Carefully check to make sure that all connections are precise and in accordance with the attached
drawings, before turning on the power
TERMINALS
The connections must be made using cables having a minimum diameter :
1,5 mm² for power cables on terminals 1, 2, 3 and 9 (Exc-, Aux/exc+, Aux)
0,5 mm² for signal cables
