5. Operating Instructions

Once properly installed and wired by a qualified professional, the Mollom HA-24 Power Distribution Box operates passively as a protective enclosure for your electrical components. Its primary function is to safely house and distribute power through the installed MCBs.

• Power On/Off: The individual MCBs inside the box control the power to specific circuits. Operate these circuit breakers as needed.
• Maintain Closure: Always ensure the transparent cover is securely closed using the double clips to maintain the IP66 rating and protect internal components from environmental elements and unauthorized access.
• Visual Inspection: Periodically check the transparent cover for any signs of damage or compromise to the seal.

6. Maintenance

Regular maintenance ensures the longevity and continued safe operation of your distribution box.

• Periodic Inspection: At least once a year, or more frequently in harsh environments, visually inspect the enclosure for any cracks, damage, or signs of wear. Check the integrity of the cable glands and the cover seal.
• Cleaning: Clean the exterior of the box with a soft, damp cloth. Do not use abrasive cleaners or solvents that could damage the ABS plastic or PC cover. Ensure the cover remains clear for visibility of internal components.
• Internal Check (by qualified personnel): If an internal inspection is required, ensure power is disconnected. Check for loose connections, corrosion, or signs of overheating on wires and terminals.

7. Troubleshooting

This section addresses common issues you might encounter. For complex electrical problems, always consult a qualified electrician.

• Water or Dust Inside Enclosure:
  • Check if the transparent cover is fully closed and the double clips are engaged.
  • Inspect the rubber gasket around the cover for damage or misalignment.
  • Ensure all cable glands are properly tightened and sealed around the cables.
• MCB Tripping Frequently:
  • This indicates an electrical fault (overload or short circuit) in the connected circuit. Consult a qualified electrician to diagnose and resolve the underlying issue.
