The system should be connected to a power supply circuit protected
by fuses with current ratings between 0.5 and 1 A / 600 V (UL listed). It
should be provided with a MCCB or equivalent device to switch off the
system from the power supply circuit. The power supply and voltage
measuring circuit is connected with cable minimum cross section of
