Connection
Connect terminals A1 and A2 to the supply voltage according to 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 protection 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 an T/R (Test/Reset) button. A parallel
connection of several test or reset inputs for testing multiple ISOMETER®s is
not allowed.
