GENERAL CONSIDERATIONS
FOR MACHINE WIRING
To reduce electromagnetic interference
(EMI) issues, avoid routing power and
communications cables together. If they
must cross, it should be at right angles,
to minimize EMI coupling. If these cables
must be run together, keep the cable lengths
as short as possible. Also, the greater the
distance between the data and power cables,
the less EMI coupling there will be between
them.
• Ideally, communications cables should
use twisted-pair wiring so any AC or
DC noise coupled to the data cable will
be balanced on each wire and will be
cancelled out in the receiving circuit.
•
For battery cables, see the tables in
the following sections for minimum
recommended cable sizes. Wire lengths
should be kept as short as is practical.
For best performance, the positive and
negative cables should run alongside
each other. Avoid cable loops.
•
Battery overcurrent protection is highly
recommended, even if it is not required
by the specific safety regulations for
