2. Safety Information
Before installing, operating, or performing maintenance on the DS675 cover assembly, read and understand all instructions and safety warnings. Failure to follow these instructions may result in serious injury or property damage.
- Qualified Personnel Only: Installation and maintenance must be performed by qualified electrical personnel familiar with hazardous location equipment and applicable codes.
- De-energize Circuit: Always ensure that power to the control station and associated circuits is disconnected and locked out before beginning any work.
- Hazardous Locations: This product is intended for Class I, Division 2 hazardous locations. Verify that the installation environment matches the product's ratings.
- Proper Sealing: Maintain the integrity of all seals and gaskets to ensure hazardous area protection.
- Use Correct Tools: Use appropriate tools for installation and removal to prevent damage to the assembly or control station.
3. Installation and Setup
The DS675 cover assembly is designed for straightforward installation onto compatible Eaton Crouse-Hinds EFS/EDS control station bodies.
- Preparation: Ensure the control station body is clean and free of debris. Verify that the gasket is properly seated in the cover assembly or on the control station body.
- Positioning: Carefully align the DS675 cover assembly with the mounting holes on the EFS/EDS control station body. Ensure that any internal components (e.g., rotary switch shaft) engage correctly with the corresponding parts in the control station.
- Securing: Insert the provided mounting screws into the designated holes. Tighten the screws evenly in a cross-pattern to ensure a uniform seal. Do not overtighten, as this can damage the gasket or housing. Refer to the control station's manual for specific torque requirements.
- Final Check: Visually inspect the installed cover assembly to confirm it is securely fastened and the gasket forms a complete seal around the perimeter.
4. Operation
The DS675 is a cover assembly and does not have independent operational functions. Its primary role is to enclose and protect the internal components of the EFS/EDS control station, such as pushbuttons, pilot lights, or selector switches, from environmental factors and to maintain the hazardous area rating of the overall assembly. Operation of the control station's functions (e.g., activating a switch) is performed via the components housed within this cover.
5. Maintenance
Regular maintenance helps ensure the longevity and continued safe operation of the DS675 cover assembly.
- Periodic Inspection: Routinely inspect the cover assembly for any signs of physical damage, corrosion, cracks, or loose mounting screws.
- Gasket Integrity: Check the gasket for signs of wear, cracking, or compression set. Replace the gasket if its integrity is compromised to maintain the NEMA 4X and hazardous area ratings.
- Cleaning: Clean the exterior of the cover assembly with a damp cloth. Avoid using harsh chemicals or abrasive cleaners that could damage the finish or seals.
- Screw Tightness: Periodically verify that all mounting screws are tightened to the manufacturer's recommended torque specifications.
