(3) Precautions on control circuit wiring
• Separate the control signal line from power lines. Otherwise, it may cause a malfunction.
• For frequency setting signal (analog), use shielded lead and conduct termination sufficiently.
• Wiring length of the control signal line must be 50 m or less.
• To drive the contact input signal by transistor, use one having ratings of 50V 50m A or more. Circuit
leakage current at signal OFF must be 100 A or less.
• To drive an inductive load (relay coil, etc.) by multifunction photo coupler output, be sure to insert a
free wheel diode.
