CAT5e Cable, 24AWG Stranded Shielded
Or
CAT6a Cable, 24AWG Stranded Shielded (to ensure
1Gbit on 100m cable and EMC performance)
For PoE application, a minimum of 24 AWG is required
to support the temperature rise.

(RG316 could also be used for lower signal loss and
higher durability, but it is less flexible and thicker.)
After the primary interconnections, the signal cables can be further extended if required to reach switches, hubs
and gate controllers as required. It is highly recommended that the maximum total length is not exceeded, as it may
result in problematic operation. The performance is not guaranteed if the extension is achieved by a huge number
of interconnections throughout the total allowed length. Signal extenders/amplifiers or additional transmitters could
be considered to maintain the performance.
Table 9: Maximum Cable Length Recommendations
It is recommended that solid core cables be avoided where possible, to improve the connection reliability of the
installed cable. If solid core is used for a CAT5e cable, extra care must be taken in crimping and restraining of
wires, and sharp bending should be avoided.
5.5 Power Supply Cable
5.5.1 Requirements
Power supply cables wired to the input of a circuit breaker must be rated with respect to the previous circuit breaker
or fuse from which they were derived. Adequate current de-rating should be applied to the cable as per the
manufacturer’s instructions.
