Always use a shield cable for connection of the CTRL 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 (0.66ft.) away.)
Connect the shield wire of the connection cable to the FG terminal of the external equipment.
Make parameter setting correctly. Incorrect setting may disable the protective functions such
as stroke limit protection.
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.
