F
If you remove the controller from its case, never touch nor apply shock to the electronic
parts inside.
F
Do not cover the top and bottom of the controller. (Ensure sufficient space around the
controller to allow heat to escape.)
F
Use a voltage (AC100-240V or AC/DC24V at 50 to 60 Hz). At power ON, the pre-
scribed voltage level must be attained within two seconds.
F
When wiring input or output lines to your controller, keep the following points in mind
to reduce the influence from inductive noise:
•
Allow adequate space between the high voltage/current power lines and the input/out-
put lines.
•
Avoid parallel or common wiring with high voltage sources and power lines carrying
large currents.
•
Using separating pipes, duct, and shielded line is also useful in protecting the controller,
and its lines form inductive noise.
F
Allow as much space as possible between the controller and devices that generate a pow-
erful, high frequency (high-frequency welders, high-frequency sewing machines, and so
forth) or surge. These devices may cause malfunctions.
F
If there is a large power-generating peripheral device and any of its lines, attach a surge
suppressor or noise filter to the device to stop the noise affecting the controller system.
In particular, motors, transformers, solenoids and magnetic coils have an inductance
component, and therefore can generate very strong noises.
F
When mounting a noise filter, be sure to first check the filter’s voltage and current
capacity, then mount the filter as close as possible to the controller.
F
Do not use the controller in places where icing, condensation, dust, corrosive gas (espe-
cially sulfurized gas or ammonia gas), shock, vibration, splashing liquid, or oil atmo-
sphere occur. Also, avoid places where the controller can be subjected to intense heat
radiation (like from a furnace) or sudden temperature changes.
F
Ambient temperature must be kept between -10
_
C to 55
_
C. Ambient humidity must be
kept between 35%RH to 85%RH (with no icing or condensation). If the controller is
installed inside a control board, the ambient temperature must be kept under 55
_
C,
including the temperature around the controller. If the controller is subjected to heat
radiation, use a fan to cool the surface of the controller to under 55
_
C.
F
Store the controller at an ambient temperature between -25
_
C to 65
_
C. The ambient
humidity must be between 35%RH to 85%RH (with no icing or condensation).
F
Never place heavy objects on, or apply pressure to the controller that may cause it to
deform and deterioration during use or storage.
F
Avoid using the controller in places near a radio, television set, or wireless installation.
These devices can cause radio disturbances which adversely affect the performance of
the controller.
