Use a ring cable lug for connecting the protective
conductor to the UMG 509.
Supply voltage
The UMG 509 needs supply voltage to operate. The type
and amount of the supply voltage required is specified
on the rating plate. The supply voltage is connected
on the rear side of the device via terminal blocks.
Before connecting the supply voltage, ensure that
the voltage and frequency correspond to the details
on the rating plate!
The supply voltage must be connected through a UL/IEC
approved fuse (6A type C).
