WARNING! Obey these instructions. If you ignore them, injury or death, or damage to the
equipment can occur.
• If you are not a qualified electrician, do not do installation or maintenance work.
• Disconnect the drive, converter or inverter from all possible power sources. After you have disconnected the
drive, converter or inverter, always wait for 5 minutes to let the intermediate circuit capacitors discharge
before you continue.
• Disconnect all dangerous voltages connected to other control signal connectors in reach. For example, it is
possible that 120/230 V AC is connected from outside to a relay output of the drive, converter or inverter.
• Always use a multimeter to make sure that there are no parts under voltage in reach. The impedance of the
multimeter must be at least 1 Mohm.

VFD-GATEWAY devices and equipment are sensitive to electrostatic discharge, which can cause internal damage
and affect normal operation.
Observe the following rules when handling the VFD-GATEWAY:
• Touch a grounded object to discharge potential static.
• Wear an approved grounding wrist strap.
• Do not touch connectors or pins on component boards.
• Do not touch circuit components inside the equipment.
• If available, use a static-safe workstation.
• When not in use, store the equipment in appropriate static-safe packaging.

Ensure the VFD-GATEWAY is grounded.
• The ground (switch cabinet earthing, PE) is supplied both by the mains connection (or 24 V supply voltage) and
via the DIN rail (if mounted).
• The DIN rail must be connected to the ground before the device is subjected to any power. The ground may be
removed only if it is certain that no more power is being supplied to the control system.

2.3 Ethernet interface
Connect your Ethernet interface via the VFD-GATEWAY RJ45 jack
Note: EtherNet cable not included. The network cable must be CAT5 or higher, and type UTP, FTP or STP.
The maximum length for an Ethernet segment on twisted pair media is 100 meters.
The VFD-GATEWAY supports twisted pair as the physical media in a star topology. All twisted pair media between the
Ethernet node and the switch or router must be shorter than 100 meters, including media within patch panels.

Disabling terminating resistors
If the gateway needs to be installed in the middle of the Modbus network, the resistor on the gateway needs to be
turned off. To do this the Modbus module on the gateway needs to be removed using the following instructions.
Ensure the VFD-GATEWAY is turned off.
Press the tab on the side of the module and pull up on the module to remove it from the VFD-GATEWAY:
After it is removed, turn the top dip-switches off. They are currently in the on position from the factory.
Flip the switches to the left for OFF (towards the ABB logo) and reinstall.

Modbus-RTU cable requirements
Make sure you use cable with the following specification for reliable Modbus-RTU performance.
Use shielded twisted-pair cable with a twisted pair for data and a wire or another pair for signal ground (nominal
impedance 100 to 165 ohm, for example Belden 9842) for the wiring. For best immunity, ABB recommends high quality
cable. Keep the cable as short as possible.
Avoid unnecessary loops and parallel runs near power cables such as motor cables.
