Pre-order check 01

Installation environment

Verify the installed mounting, connection and environmental conditions before this exact configuration is removed or energized.

Seat DX531 on the documented i/o bus through tu531 or tu532 terminal unit arrangement and inspect every mating contact before power is applied.
Record the installed relay outputs as 4 change-over contacts and preserve the existing terminal or network labels.
Check enclosure protection, horizontal or vertical mounting, airflow, temperature and conductor strain against the ABB installation instructions.
After energization, verify status indicators, diagnostics and the controlled ac status acquisition with change-over relay control test before returning the loop or network to service.

Record the as-found installation and final controlled checks in the commissioning file.
