Fuji Electric POD UG221H-LE4 User Manual page 6

[General Notes]
• Never bundle control cables and 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 POD 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 POD in the correct orientation. Otherwise, it may cause a malfunction.
• Do not use thinners for cleaning because they may discolor the POD surface. Use alcohol or benzine
commercially available.
• If a data receive error occurs when POD and the counterpart (PLC, temperature controller, etc.) are started at
the same time, read the manual for the counterpart unit and handle the error correctly.
• Avoid discharging static electricity on the mounting panel of the POD. 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.
• The POD has no electrical insulation between 0 V for the input power supply and 0 V for the internal voltage
(SG), or for the communication circuit (non-insulated power system used). Take this into account in system
design.
