5. Connection
5.1 Wiring
IR1575PG1 has plug-in terminals.
Connect the terminals A0/A1 respectively A0/A2 to the supply voltage Us in accordance
with IEC 60364-4-43. The connections to the supply voltage shall be provided with pro-
tective devices to afford protection in the event of a short circuit (a 6 A fuse is recom-
mended).
Devices for protection against short circuit in conformity with IEC 60364-4-473 for the
IT system coupling L1/L2/L3 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 (a short-circuit-proof and insulati-
on-fault-proof wiring is recommended).
Only one ISOMETER® may be connected to an external TEST or RESET button. A galvanic
parallel connection of several TEST and RESET inputs for collective testing of
ISOMETER®s is not permitted.
