Rittal mounting unit DK 7030.071 for CMC III, Width 170 mm, Depth 160 mm, Height 44.2 mm

Rittal mounting unit DK 7030.071 is designed to provide a precise and secure interface for installing the CMC III climate/monitoring controller and related modules in control cabinets and industrial enclosures. With an external footprint of 170 × 160 × 44.2 mm, the unit accepts the CMC III and compatible control units including PU, PU Compact, CMC III CAN‑Bus unit and CMC III power pack. The device is mounted on the enclosure frame and allows front insertion and automatic locking of the accommodation component, while the rear section includes an integrated cable clamping facility.

Advantages

The mounting unit offers a compact and standardized mounting solution that ensures correct cutout dimensions and repeatable installation of the CMC III family and related modules. Front insertion with automatic locking simplifies installation and replacement without access to the enclosure interior. Integrated cable clamping in the rear improves cable strain relief and helps maintain orderly wiring inside the cabinet.

Suitable for (tasks / use cases)

• Mounting CMC III climate/monitoring controllers in industrial control cabinets
• Installing PU, PU Compact, CMC III CAN‑Bus unit or CMC III power pack in enclosures
• Retrofit or new-build electrical cabinets requiring a defined cutout for monitoring hardware
• Applications where front access for service or replacement is required

When it may not be suitable

This mounting unit is specific to the CMC III family and compatible modules; it may not be suitable for controllers or devices with different form factors or mounting interfaces. If your application requires additional features such as integrated filters, extended environmental sealing, or non‑standard panel thicknesses, verify compatibility before selection.

Key specifications

• External dimensions: width 170 mm × depth 160 mm × height 44.2 mm
• Designed to accommodate: CMC III controller and compatible PU, PU Compact, CAN‑Bus unit, power pack
• Mounting method: mounted on enclosure frame with front insertion of the accommodation component
• Locking: automatic front locking of the inserted component
• Cable management: integrated cable clamping facility at rear for strain relief
• Capacity: accommodates up to 1 unit

How to use

Install the mounting unit in the prepared cutout of the enclosure frame according to the cabinet manufacturer’s instructions. Insert the CMC III or compatible module from the front until the automatic locking mechanism engages. Route the supply and signal cables to the rear of the unit and secure them using the integrated cable clamping facility to provide strain relief. For removal, release the front locking mechanism and pull the accommodation component out towards the front.

What to consider before purchase

• Confirm device compatibility with the CMC III family and specified modules (PU, PU Compact, CAN‑Bus unit, power pack)
• Verify enclosure frame thickness and cutout dimensions to match the unit's external dimensions
• Check available space behind the mounting position for cabling and the integrated cable clamp
• Ensure the mounting method matches the cabinet design (frame mounting with front access)

Usage recommendations

For reliable operation, perform installation and wiring according to local electrical standards and the controller manufacturer’s instructions. Use the integrated cable clamping to secure conductors and avoid placing heavy cable bundles directly on the inserted module. When servicing, make sure power is disconnected and follow safe working practices to avoid damage to the controller or wiring.
