8. Wiring precautions For wiring connections note the following 1 If an electromagnetic contactor is inserted between the inverter and motor for start and stop a rush start current flow is caused letting excessive current flow thereby giving rise to overcurrent tripping of the inverter Repeated operation may damage the element therefore avoid inserting an electromagnetic contactor where applicable When it is used be sure to turn it ON after both the in verter and motor stop a 78s 2 Absolutely avoid connecting a phase advance capacitor and surge absorber between the inverter and motor 3 Insert a circuit breaker into the power supply side to protect the wires Do not use a blade type switch only instead of the circuit breaker Phase fault may result 4 Use a shielded wire for a signal line and process it as shown in Fig 6 below The wire length should be less than 20m If the wire length unavoidably exceeds 20m use optional VX application controller CVD E signal isolation converter Insulate here No earth connection is required Connect this lead i to the inverter s earth PE Fig 6 Shield Processing 5 Select a signal line switch or relay for weak current which can be used at 12V DC 3 mA for control circuit terminals except for AL1 AL2 and ALO 6 Separate the inverter signal line from the power line as shown in Fig 7 below If cross over is unavoid
