4. Connection

DANGER
IRDH575 has plug-in terminals.
Connect the terminals A1/+ and A2/- to the supply voltage U
with IEC 60364-4-43. The connections to the supply voltage shall be provided
with protective devices to afford protection in the event of a short-circuit (a 6
A fuse is recommended).
For UL and CSA applications, the use of 5 A fuses is mandatory.
Devices for protection against short-circuit in conformity with
IEC 60364-4-43 for the IT system coupling L1/L2/L3 can be omitted if the wi-
ring is carried out in such a manner as to reduce the risk of a short-circuited to
a minimum (a short-circuit-proof and earth-fault-proof wiring is recommen-
ded).
Use the accompanying terminal covers for terminal protection.
