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 pro-
tection against short-circuit in conformity with IEC 0100-430 for the coupling
of terminals L+/L- to the IT system to be monitored can be omitted if the wi-
ring 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) but-
ton. A parallel connection of several test or reset inputs for testing multiple
ISOMETER®s is not allowed.
