The rear panel includes a cable entry to ensure organized cabling. The lid and base are fitted with ventilation slots to support sufficient air circulation and cooling of the installed components. The cabinet is designed for indoor use and complies with protection class IP20, meaning it is protected against contact with fingers and against solid foreign objects up to 2.5 mm in diameter. The external dimensions are 554 mm (width) × 978 mm (height) × 600 mm (depth).

Applications
This cabinet is suitable for use in small to medium-sized network infrastructures, such as those found in offices, administrative buildings, or small server rooms. It provides sufficient space for network devices, switches, routers, and other 48,3 cm ( 19 inch ) components. The integrated cable entry and ventilation slots on the lid and base support structured and efficient installation. The lockable full-glass door ensures secure access and prevents unauthorized manipulation.

Functions and Equipment in Detail
The cabinet is supplied with a set of 48,3 cm ( 19 inch ) mounting profiles, consisting of four vertical T-slot profiles, enabling flexible device mounting. The T-slot profiles are standardly designed for mounting IT components and allow secure fastening. An earthing kit with M8 earthing bolt is also included in the delivery scope to ensure safe electrical earthing of the cabinet. The Light Grey (RAL7035) finish blends well into typical office and server environments.

Technology Explained Simply
The IP20 protection class means the cabinet is protected against contact with fingers and against the ingress of solid foreign objects with a diameter of at least 2.5 mm. It is not suitable for outdoor use or in damp environments. The usable depth of 435 mm allows mounting of devices that are not deeper than this value. The ventilation slots on the lid and base support natural convection cooling, helping to regulate the temperature inside the cabinet. The lockable full-glass door provides a clear overview of the installed components without compromising security.

Compatibility and Accessories
Various accessories are available for extending or adapting the cabinet. These include double castor sets in heights 63 mm and 95 mm with M8 thread, enabling mobile use. A fan rear panel set (B554, Light Grey) can be installed to improve cooling. Additionally, a mounting kit T-slot M5, small, is available for additional mounting tasks.

Mounting and Installation
Mounting is performed using the integrated 48,3 cm ( 19 inch ) T-slot profiles, which allow secure fastening of devices. Earthing is achieved via the included earthing kit with M8 earthing bolt. The cable entry on the rear panel facilitates cabling, allowing cables to be neatly routed and organized. The ventilation slots on the lid and base ensure sufficient air circulation, which should be considered during installation to ensure optimal cooling.

Operational Advantages
The cabinet offers a compact yet functional solution for use in small networks. The integrated T-slot profiles and earthing kit simplify installation. The lockable full-glass door ensures security and clarity. The ventilation slots support cooling, which can extend the lifespan of installed devices. The Light Grey (RAL7035) finish blends well into typical work environments.
