4.2: Operational Environment
This section discusses the type of installation
required depending on the electrical environment.
4.2.1: Residential, Commercial and Light
Industrial Environments
Typically, this will be an office, laboratory
or industrial environment where there is no
equipment likely to produce high levels of electrical
interference, such as welders or machine tools.
Connections may be made using twisted,
unscreened wire. This is a cost effective option and
will give good performance in this environment.
Standard equipment wire such as 7/0.2 (24 AWG)
can be twisted together as required. Standard data
cable such as generic CAT5 UTP will also give good
performance.
4.2.2: Industrial Environments
Typically, this will be an industrial environment
where there is equipment likely to produce high
levels of electrical interference, such as welders,
machine tools, cutting and stamping machines.
Connections should be made using screened cable.
Braided or foil screened cables may be used. The
cable screen should be connected to the OD4 case
at cable entry point. The case of the OD4 should be
connected to a local ground. An EMC cable gland is
recommended.
This is supplied with the OD4.
When selecting the type of wire or cable to be used,
consider the following parameters:
• Screening.
Conductor size (resistance).
Mechanical aspects such as flexibility
and robustness.
This is not a complete list. Installations may require
other special cable characteristics.
