7.15.7 Enclosure, wiring
Wiring examples (
# 45). Observe the required ambient conditions as described in chapter
The AKD-C (IP 20) must be mounted in an IP54 cabinet to ensure pollution level 2 according
to IEC 60664-1. Connector X16 (STO signals) ensures requirements of pollution level 3
according to IEC 60664-1.
The AKD-N can be used in an environment that meet IP67.
Wiring inside the cabinet
Wiring remaining must meet the requirements of the standard IEC 60204-1. In compliance
with the safety standard ISO 13849-2 Table D.4; short-circuits between conductors or of any
conductor to an exposed conductive part can be excluded when:
permanently connected (fixed) and protected against external damage, e. g. by cable duct-
ing, armouring, or
within separate multicore cables, or
within the IP54 electrical enclosure, or
individually shielded with earth connection.
This is valid also for the STO wiring of AKD-C.
Wiring outside the cabinet
If you are wiring leads that are outside the specified enclosure (IP54), the cables must be laid
durably (firmly), protected from outside damage (for example, by laying the cable in a duct),
placed in different sheathed cables, or protected individually by grounding connection.
Maximum cable length
Maximum cable length for safety relevant I/Os and for the 24 V supply is 30 m.
