– Pay attention to identical directions of flow on the two measuring clamps (see connection
diagram). For this purpose the measuring clamps are marked with an arrow
Place the two measuring clamps successively and systematically around all parallel outgoing cables
for loads. Outgoing cables for loads with an insulation fault are indicated by the flashing alarm LED
on the EDS195P. The alarm messages are output in the same way as for an application with a single
measuring clamp. For possible error messages see page 44.
