- Places subject to direct sunlight.
- Places subject to dust or corrosive gas (in particular,
sulfide gas and ammonia gas).
- Places subject to intense temperature change.
- Places subject to icing and condensation.
- Places subject to vibration and large shocks.
• Installing two or more controllers in close proximity
might lead to increased internal temperature and this
might shorten the life cycle of electronic components. It
is strongly recommended to install cooling fans or other
air-conditioning devices inside the control cabinet.
• Always check the terminal names and polarity and be sure
to wire properly. Do not wire the terminals that are not
used.
• To avoid inductive noise, keep the controller wiring
away from power cables that carry high voltages or
large currents. Also, do not wire power lines together
with or parallel to Digital Controller wiring. Using
shielded cables and using separate conduits or ducts is
recommended. Attach a surge suppressor or noise filter
to peripheral devices that generate noise (in particular
motors, transformers, solenoids, magnetic coils or other
equipment that have an inductance component). When
a noise filter is used at the power supply, first check the
voltage or current, and attach the noise filter as close as
possible to the Digital Controller. Allow as much space
as possible between the Digital Controller and devices
that generate powerful high frequencies (high-frequency
welders, high-frequency sewing machines, etc.) or surge.
• A switch or circuit breaker must be provided close to
device. The switch or circuit breaker must be within
easy reach of the operator, and must be marked as a
disconnecting means for the controller.
• The device must be protected by a fuse 1A (cl. 9.6.2).
• Wipe off any dirt from the Digital Controller with a soft
dry cloth. Never use thinners, benzine, alcohol, or any
cleaners that contain these or other organic solvents.
