How to use

Install the accessory into the rack at a convenient height to serve the intended function — for example, near terminal blocks or control devices. Ensure the rack mounting points align with the accessory mounting features and secure it according to the rack system manufacturer’s instructions. Route cables and place small components or tools inside the accessory to keep them separate from larger equipment and to maintain orderly cable paths.

Recommendations

Place the UD21B1 in positions that minimise cable crossing and provide easy access for routine checks. Use the multicolour aspect to mark specific service zones or to assist identification during maintenance. Verify load and clearances in the rack before final placement to ensure adequate airflow and safety clearances are preserved.
