Ensure proper air supply quality (dry, filtered, and oil-free) to avoid internal contamination.
Verify that the supply pressure does not exceed the specified maximum (6 bar).
Install in accordance with ABB’s mounting guidelines for linear or rotary actuators.
For hazardous environments, ensure the correct explosion-proof version is used.
Perform regular calibration and diagnostics using ABB’s configuration software or handheld communicator.
Protect the device from excessive vibration and mechanical shock.
Always disconnect the 4–20 mA signal and air supply before performing maintenance.
