4. Functionality
The DK-35A DIN Rail Mounting Kit functions as an intermediary mechanical interface between an electrical or electronic device and a standardized DIN rail. Each adapter attaches to the rear side of the device’s enclosure using the provided screws. Once secured, the adapters allow the device to be clipped or slid onto a 35 mm DIN rail, locking it firmly in place.

Use Cases and Applications:
- Mounting of compact control units, signal converters, or interface modules in industrial control panels.
- Installation of power supplies, relays, and timers in automation cabinets.
- Integration of communication modules, I/O interfaces, or small PLCs onto DIN rails.
- Retrofitting or upgrading existing enclosures to DIN rail compatibility.
- Laboratory and test bench setups requiring modular and reconfigurable mounting solutions.

Compatibility:
- Compatible with all standard 35 mm DIN rails (EN 60715 / TS35).
- Suitable for use with enclosures or devices featuring flat rear surfaces or pre-drilled mounting holes.
- Can be used with both metal and plastic enclosures.

5. Components & Accessories
Included in the DK-35A Kit:
- 2 × DIN Rail Adapters (Grey): Molded polymer components designed to engage securely with the DIN rail profile.
- 4 × Mounting Screws (V2A Stainless Steel): Precision-threaded screws for fastening adapters to the device housing.

Optional Accessories (not included):
- Additional DIN rail sections (TS35, 7.5 mm or 15 mm height).
- End stops or rail clamps for securing devices along the rail.
- Grounding clips or conductive mounting plates (for metal enclosures).
- Cable management accessories for routing and securing wiring near mounted devices.

Connectors and Interfaces:
- Mechanical interface only (no electrical connectivity).
- Screw holes designed for standard M3 or M4 thread sizes (depending on device compatibility).

6. Installation & Setup
Requirements:
- Compatible device or enclosure with flat rear surface or mounting holes.
- Standard 35 mm DIN rail (TS35) installed in the control cabinet or panel.
- Basic hand tools (screwdriver, possibly drill if retrofitting).

Installation Steps:
1. Preparation: Verify that the device’s rear surface is clean and free of debris.
2. Adapter Attachment: Align the two DK-35A adapters on the back of the device, ensuring even spacing for balanced support.
3. Screw Mounting: Use the four provided V2A screws to fasten the adapters securely to the device. Tighten to recommended torque (typically 0.5–1.0 Nm).
4. DIN Rail Mounting: Position the device with attached adapters onto the DIN rail. Engage the upper lip of the adapter with the top edge of the rail, then press downward until the lower latch clicks into place.
5. Verification: Ensure the device is firmly seated and cannot move laterally or vertically under normal operating conditions.

Mounting Options:
- Vertical or horizontal orientation depending on device design.
- Can be used in both fixed and removable configurations.
- Suitable for both wall-mounted and cabinet-mounted DIN rails.

Configuration:
- No electrical configuration required.
- Mechanical alignment only.
