Figure A.1 Connecting the SLM cable to the connectors (only the
relevant parts of the connectors are shown)
Incorrect wiring of this cable could result in failure of
the M'Ax or SLM
CAUTION
1. 8-way shielded cable having an overall diameter not greater than
1
6.6mm ( / in)
4
2. Maximum length: 50m (165ft)
3. Route the cable by the shortest convenient path and so that it is no
closer than 300mm (1ft) from any power cable.
4. Overall shield of tinned copper braid. Comb out the braid at both
ends, fold the strands back and trap them under the cable clamp to
ensure good electrical contact with the connector shell.
5. The required twisted pairs connected to the DIN connector, the
unwanted twisted pairs should be cut at each end and insulated to
prevent inadvertent contact.
6. Make the wire ends as short as possible (this affects performance).
7. Amphenol C091 31D005 100 2 5-way screw-locking DIN connector
meeting IP67.
8. Shielded RJ45 8-way plug
D-type connectors
For connection to the following connectors on the Drive...
• SIM ENC
• MC/EIA485
• DIGITAL I/O
• STANDALONE
... use the following:
Cables
Multi-core cables having tinned-copper stranded conductors, overall
braided shield and braided outer sheath
Maximum overall diameter: depends on the D-type connector being
used
