Back-up fuse of the supply voltage
The supply and measuring voltages of all system components are to be secured with back-up fuses. The
back-up fuses are to be dimensioned according to the conductor cross-section used.
We recommend securing the output relay against the danger of short-circuit with a 5A fast acting fuse!
