2-2 Wiring Wiring Example of the Control Circuit Terminal Block (Sink Logic) 2 Design Frequency meter Frequency arrival signal (27 V DC 50 mA max.) Note 1: When connecting a relay to the multi-function output terminal, install a surge-absorbing diode in parallel with the relay. The output circuit can break down due to surge voltage when the relay is switched on/off. Note 2: Remove the short-circuit bar when the external power supply is used. Note 3: For the signal line, use a twisted shield wire and apply the shield coating as illustrated below. Keep the length to 20 m or less. Perform insulating treatment. Ground connection is not required. Connect to the ground terminal of the Inverter.
Note 4: Keep the wiring away from the power cable of the main circuit and from the wiring on the relay control circuit.
