Wiring diagram

Connect terminals " A1 " and " A2 " to the supply voltage U
IEC 60364-4-43, i.e. the connections are to be protected against short circuit
by means of a protective device (a 6 A fuse is recommended). Devices for pro-
tection against short-circuit in conformity with IEC 0100-430 for the coupling
of terminals " L1/+ " / " L2/- " to the IT system to be monitored can be omitted if
the wiring is carried out in such a manner as to reduce the risk of a short-circuit
to a minimum.
Only one ISOMETER® may be controlled via a test/reset button. It is not allo-
wed to use a parallel connection of several test or reset inputs for combined
testing of ISOMETER®s.
