Safety Precautions
[General Notes]
• Never bundle control cables nor input/output cables with high-voltage and large-current carrying cables such as
power supply cables. Keep these cables at least 200 mm away from the high-voltage and large-current carrying
cables. Otherwise, malfunction may occur due to noise.
• When using @E.Terminal in an environment where a source of high-frequency noise is present, it is recommended
that the FG shielded cable (communication cable) be grounded at its ends. However, the cable may be grounded
only at one end if this is necessary due to unstable communication conditions or for any other reason.
• Plug connectors or sockets of @E.Terminal in the correct orientation. Failure to do so may lead to damage or
malfunction.
• If a LAN cable is inserted into the MJ1 or MJ2 connector on @E.Terminal, the counterpart device may be
damaged. Check the indication on the unit and insert a cable into the correct position.
• Do not use thinners for cleaning because they may discolor @E.Terminal surface. Use alcohol or benzine
commercially available.
• If a data receive error occurs when @E.Terminal and the counterpart (PLC, temperature controller, etc.) are
started at the same time, read the manual for the counterpart unit and remove the error correctly.
• Avoid discharging static electricity on the mounting panel of @E.Terminal. Static charges can damage the unit and
cause malfunctions. Otherwise, malfunction may occur due to noise.
• Avoid prolonged display of any fixed pattern. Due to the characteristics of the liquid crystal display, an afterimage
may occur. If a prolonged display of a fixed pattern is expected, use the auto OFF function of the backlight.
[Notes on LCD]
Note that the following conditions may occur under normal circumstances.
• The response time, brightness and colors of @E.Terminal may be affected by the ambient temperature.
• Tiny spots (dark or luminescent) may appear on the display due to the liquid crystal characteristics.
• There are variations in brightness and colors on each unit.
• Cold cathode tubes are incorporated into the LCD display for backlights. Optical properties (brightness, irregular
colors, etc.) may change in a low-temperature environment or over time of operation.
