4. Setup and Installation
Before beginning installation, ensure all power to the circuit is OFF at the main breaker panel. This device must be installed by a qualified professional.
- Mounting: Select a suitable outdoor location for the disconnect box, ensuring it is within sight of the equipment it serves. Use the two-point mounting holes to securely fasten the enclosure to a stable surface.
- Knockouts: Utilize the pre-punched knockouts (sized for 1/2", 3/4", and 1" conduit and cable) to bring the supply and load wires into the enclosure. Remove knockouts carefully to avoid damage.
- Wiring: Connect the supply (LINE) wires to the designated LINE terminals and the load (LOAD) wires to the designated LOAD terminals. Connect the equipment ground wire to the ground lug. Refer to the internal label for clear line/load orientation and accepted wire ranges.
- Torque Specifications: Ensure all terminal screws are tightened to the specified torque values to prevent loose connections and potential hazards. Consult the table below for detailed lug specifications.
- Close and Secure: Once wiring is complete and verified, replace the cover and ensure it is securely latched. The door is padlockable for added security.

5. Operating Instructions
The Halex HNF60R disconnect operates using a simple pull-out switch mechanism.
- To Disconnect Power (OFF): Firmly grasp the pull-out switch handle and pull it straight out from the enclosure. This action physically separates the electrical contacts, interrupting the power supply to the connected equipment. The switch is clearly marked with ON/OFF indicators.
- To Connect Power (ON): Align the pull-out switch with the slots in the enclosure and push it firmly into place until it is fully seated. This action engages the electrical contacts, restoring power to the connected equipment.
- Safety Lockout: For added safety during maintenance, the pull-out switch can be removed and stored separately, or the enclosure door can be padlocked in the OFF position to prevent accidental re-energization.

6. Maintenance
The Halex HNF60R non-fused disconnect is designed for minimal maintenance due to its robust construction and NEMA 3R rating.
- Periodic Inspection: Annually inspect the enclosure for any signs of physical damage, corrosion, or loose connections. Ensure the door latch operates correctly and the enclosure remains sealed.
- Cleaning: Keep the exterior of the enclosure clean from dirt, dust, and debris. Use a damp cloth if necessary. Do not use abrasive cleaners or solvents.
- Terminal Check: If the enclosure is opened for any reason, visually inspect the wire terminals for tightness and signs of overheating. Re-torque connections if necessary, ensuring power is disconnected first.
7. Troubleshooting
If you experience issues with your Halex HNF60R disconnect, consider the following common troubleshooting steps:
- No Power to Equipment:
- Ensure the pull-out switch is fully inserted into the ON position.
- Check the main circuit breaker in your electrical panel to ensure it has not tripped.
- Verify all wire connections within the disconnect are secure (only by a qualified electrician with power off).
- Difficulty Inserting/Removing Pull-Out Switch:
- Ensure the switch is aligned correctly with the guide slots.
- Check for any obstructions or debris within the switch mechanism.
- Visible Damage to Enclosure or Components:
- If any part of the disconnect is damaged, discontinue use immediately and contact a qualified electrician for replacement.
For issues not resolved by these steps, professional electrical assistance is recommended.
