Run the cable through the wiring hole on the AV550G. Fix the cable with a cable gland, if necessary.
Open the common mode filter supplied, and wind one turn of the two conductors on it. The cable
length between the common mode filter and the wiring hole should not exceed 5 cm.
Close the common mode filter, taking care not to catch the cable in it, and then lock it.
Connect the cable on the positive (+) side of the Fieldbus power supply to terminal 5 on the control
card, and connect the cable on the negative (-) side to terminal 6. Use the M3.5 screw terminals.
Connect the shield to the cable shield ground terminal on the AV550G. The shield length to the
terminal should be as short as possible and the excess length should be cut off. Use the M4 screw
terminal.
• Host:
This is a PC used to access the Fieldbus devices. In a control system, the host would normally
be a DCS or the like, but in a test setup we can use a Fieldbus communications software tool
running on a PC for the host. We won’t describe the operation of the host software in detail here;
refer to its Instruction Manual.
