CAUTION
Always use a shield cable for connection of the SY.ENC connector and external equipment, and
avoid running it close to or bundling it with the power and main circuit cables to minimize the
influence of electromagnetic interface. (Separate them more than 200mm (0.66 ft.) away.)
Connect the shield wire of the connection cable to the FG terminal of the external equipment.
When increasing the cable length, use the cable 30m(98.43ft.) or less. Note that the cable should
be run in the shortest possible distance to avoid induced noise.
Always wire the cables when power is off. Not doing so may damage the circuit of modules.
Wire the cable correctly. Wrong wiring may damage the internal circuit.
