How to use

Place the cabinet on a level surface and secure the levelling feet. If required, detach side panels or doors to facilitate equipment installation. Mount equipment on the galvanised 19" profiles using the supplied captive nuts; adjust profile depth as needed. Route cables through the pre-punched roof or bottom openings and install fan units or filter modules in the roof or bottom openings as required. Connect the earthing bar and earthing cables to building ground according to local regulations. Lock front and rear doors with the included profile half-cylinder to restrict access.

Recommendations

For safe and reliable operation, distribute equipment weight evenly and respect the maximum load rating. Use the designated cable entry points and maintain unobstructed airflow through fan units; ensure earthing connections are verified by qualified personnel.
