Wiring examples 3UG4583 insulation monitoring relays
Measuring inputs L+ and L- can be connected to any conductor (phase or N conductor).
Measuring inputs L+ and L- must always be connected to different conductors.
The rated system voltage is U
n
≤ 400 V AC (15 to 400 Hz) or U
n
≤ 600 V DC. The 3UG4983-
1A upstream module must be used to monitor systems with higher voltages.
