Outline and dimensions of installation

The installation of MNS series switchgear cabinets is a non-wall-flush vertical installation. The rear of the cabinet faces the outgoing cable trench. To facilitate maintenance, the distance from the rear to the wall is typically 800–1200mm, while the front side distance is determined according to installation requirements.
