NOTE
When connecting the phase (L1) to terminal 1 and the neutral conductor (N) to termi-
nal 2 (Ph-N 100V – 240V+/-10% DC/50Hz/60Hz) the safety device and the disconnector
in the supply line to terminal 2 (N) are not required.
The safety device and the disconnector to terminal 2 (N) are only required for the
following connection variants:
Alternating voltage:
Terminal 1 (L1) and terminal 2 (L2):
US1 Phase-Phase 100V - 240V +/-10% 50Hz/60 Hz
Direct voltage:
Terminal 1 (+) and terminal 2 (-):
US1 100V - 240V +/-10% DC
