Open the contact by inserting a small screwdriverinto the slot above or below the contact, asshown in Figure 2.13.2. Insert the bared control wire into the contact.3. Remove the screwdriver to fasten the control wireinto the contact.4. Ensure the contact is firmly established and notloose. Loose control wiring can be the source ofequipment faults or less than optimal operation.See 10.1 Power-dependent Specifications for control terminalwiring sizes.See 6 Application Examples for typical control wiringconnections.2110 mm130BA310.1012 13 18 19 27 29 32 33Figure 2.13 Connecting Control Wiring2.4.5.4 Using Shielded Control CablesCorrect shieldingThe preferred method in most cases is to secure controland serial communication cables with shielding clampsprovided at both ends to ensure best possible highfrequency cable contact.If the ground potential between the adjustable frequencydrive and the PLC is different, electric noise may occur thatwill disturb the entire system.
