Safety Information
Always adhere to local electrical codes and regulations during installation. Installation should only be performed by qualified personnel. Disconnect all power before working on or inside the enclosure. Failure to follow these instructions may result in electric shock, fire, or serious injury.
- Ensure the enclosure is properly grounded.
- Do not exceed the maximum electrical ratings of any components installed within the enclosure.
- Verify that all connections are secure and insulated.
- Keep the enclosure door securely closed when not performing maintenance.
Setup and Installation
The Orbit 16164R enclosure is designed for screw-in installation. Follow these general steps for mounting:
- Site Selection: Choose a flat, stable, and accessible surface for mounting. Ensure the location provides adequate clearance for opening the enclosure door and performing maintenance.
- Marking: Use the pre-drilled mounting holes on the back of the enclosure as a template to mark the drilling points on the mounting surface.
- Drilling: Drill pilot holes at the marked locations, ensuring the drill bit size is appropriate for your mounting hardware.
- Mounting: Secure the enclosure to the surface using appropriate screws, bolts, or anchors. Ensure the enclosure is level and firmly attached.
- Cable Entry: Plan for cable entry points. Ensure proper cable glands or conduit fittings are used to maintain the NEMA 3R rating and prevent water ingress.
- Internal Component Installation: Install electrical components, terminal blocks, or other equipment inside the enclosure as required, ensuring proper spacing and wire management.
- Grounding: Connect the enclosure to a reliable earth ground as per local electrical codes.
- Final Check: Before energizing, double-check all connections, ensure the door closes securely, and confirm all safety measures are in place.
Operation
The Orbit 16164R functions as a protective housing for electrical installations. Its primary operation involves providing a secure and weather-resistant environment for internal components. Once installed and wired, ensure the screw cover is tightly fastened to maintain the NEMA 3R rating, which protects against rain, sleet, external ice formation, and provides protection against accidental contact with enclosed equipment.
Maintenance
Regular maintenance will prolong the life of your Orbit electrical enclosure and ensure continued protection for your electrical components.
- Cleaning: Periodically clean the exterior of the enclosure with a soft, damp cloth to remove dirt and debris. Avoid abrasive cleaners that could damage the powder-coated finish.
- Inspection: Annually inspect the enclosure for any signs of damage, corrosion, or wear. Check the integrity of the screw cover and ensure it seals properly.
- Mounting Hardware: Verify that all mounting screws or bolts remain tight and secure. Re-tighten if necessary.
- Internal Check: If safe to do so (with power disconnected), periodically open the enclosure to inspect internal components for dust, moisture, or signs of overheating.
Troubleshooting
Most issues related to the enclosure itself are physical in nature. If you encounter problems, consider the following:
- Water Ingress: If water is found inside the enclosure, check the integrity of the screw cover seal, cable entry points, and any conduit connections. Ensure all fittings are properly sealed and tightened.
- Corrosion/Damage: If the powder coating is chipped or the steel is corroding, clean the affected area and apply a suitable rust-inhibiting paint to prevent further degradation. For significant structural damage, the enclosure may need replacement.
- Loose Mounting: If the enclosure feels loose on its mounting surface, re-tighten the mounting hardware. If the mounting surface is compromised, reinforce it or relocate the enclosure.
