F If you remove the controller from its case, never touch nor apply shock to the elec-
tronic parts inside.
F Do not cover the area around the E5EK. (Ensure sufficient space around the control -
ler to allow heat radiation.)
F Use a voltage (AC100-240V
or AC/DC24V at 50 to 60 Hz). At power ON, the pre-
scribed voltage level must b e 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/
output 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 con-
troller, and its lines form inductive noise.
F Allow as much space as possible between the controller and devices that generate a
powerful, high frequency (high-frequency welders, high-frequency sewing machines,
and so forth) o r 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 p articular, motors, transfo rmers, 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
(especially sulfurized gas or ammonia gas), shock, vibration, splashing liquid, or oil
atmosphere 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_Cto55_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_Cto65_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 installa-
tion. These devices can cause radio disturbances which adversely affect the perfor-
mance of the controller.
