Fig. Connection example UMG 801 with residual current monitoring via 2 multifunction channels (7/8, 9/10) as measuring inputs for the
residual currents.
CAUTION
Risk of injury or damage to the meter/your
system due to short circuit!
Inadequate insulation of the operating equipment
at the residual current measuring input with respect
to the supply circuits can cause voltages at the
measuring input which represent a hazard when
touched or damage to your device or system.
· Ensure reinforced or double insulation with
respect to the supply circuits!
· Isolate residual current measuring inputs
galvanically from each other and galvanically
from the supply voltage (24 V)!
