fuse to ensure that the current flow is interrupted if an error occurs. U
U can be protected with a fuse cut-out each acc. to EN 60127-2 or with an
LS
electronic fuse each. Fuse cut-outs have to comply with the following techni‐
cal specifications acc. to EN 60127-2:
● G-fuse cartridge
● Rated current 4 A
● Slow-blow
● Current pulse insensitive
● Large or increased circuit-breaking capacity
● Rated voltage ≥ 60 V DC
● Time-current characteristics: 275 % of the nominal current, correspond‐
ing to 11 A, maximum 80 s
NOTICE
To rule a short circuit of the voltage supply U
is required, that the wires U
according to EN 60204-1 or EN ISO 13849-2. The shield requires a coverage
of 85 % and has to be defined and reliably connected to the connector.
NOTICE
Connect the ground shield of the connecting lead to the functional ground
connection FE of the non-reactive modules to the 0 V U
Moreover, an insulation monitoring can be used according to EN 61557.
