This manual contains information and warnings about the RGU-10/RGU-10C which must be followed to guarantee
the proper operation of all instrument functions and to maintain it in a safe condition. The equipment must not be
switched on until it is finally connected to the electrical board.
IF THE EQUIPMENT IS HANDLED IN A WAY NOT SPECIFIED BY THE MANUFACTURER, THE EQUIPMENT'S
PROTECTION MAY BE COMPROMISED
When it is likely that the equipment has lost its protection (i.e. with visible damage), it must be disconnected from the
auxiliary supply. In this event, contact a qualified technical service representative.
