3. Safety Information

Adherence to safety precautions is paramount when working with electrical equipment. Failure to comply can result in severe injury or death.

• Qualified Personnel Only: Installation, operation, and maintenance must be performed by qualified electrical personnel who have been trained and understand the hazards involved.
• Disconnect Power: Always turn off and lock out/tag out all power supplying this equipment before working on or inside the switch.
• Verify Voltage: Always use a properly rated voltage sensing device to confirm power is off.
• Personal Protective Equipment (PPE): Wear appropriate PPE, including arc flash protection, as required by local codes and safety standards.
• Proper Grounding: Ensure the switch is correctly grounded according to all applicable electrical codes.
• Fuse Replacement: Only replace fuses with those of the correct type and rating (60 Amps). Never bypass or use incorrect fuses.

4. Installation

Follow these steps for proper installation:

1. Pre-Installation Check: Inspect the switch for any shipping damage. Ensure all components are present.
2. Mounting: Securely mount the NEMA Type 3R metallic enclosure to a rigid, flat surface using appropriate hardware. Ensure the mounting location allows for proper ventilation and access for operation and maintenance.
3. Wiring:
   • Turn off the main power supply at the source before beginning any wiring.
   • Open the switch enclosure door.
   • Connect the incoming power conductors to the line terminals and the outgoing load conductors to the load terminals. Ensure all connections are tight and conform to local and national electrical codes.
   • Connect the neutral conductor to the neutral bar.
   • Install a service grounding kit if the switch is used as service entrance equipment, and connect the grounding conductor to the ground lug.
4. Fuse Installation: Insert two 60 Amp fuses of the correct type into the designated fuse holders.
5. Enclosure Closure: Close and secure the enclosure door. Ensure all conduit entries are properly sealed to maintain the NEMA 3R rating.
6. Power Restoration: Once installation is complete and verified by qualified personnel, restore power to the system.

5. Operation

The D222NRBCP safety switch is operated via a hinge lever mechanism.

• To Turn ON: Firmly push the operating handle upwards until it locks into the 'ON' position.
• To Turn OFF: Firmly pull the operating handle downwards until it locks into the 'OFF' position.
• Fuse Replacement: Always ensure the switch is in the 'OFF' position and all power is disconnected before opening the enclosure to replace fuses. Replace only with 60 Amp fuses of the specified type.

6. Maintenance

Regular maintenance ensures the longevity and safe operation of your safety switch.

• Periodic Inspection: Annually, or more frequently in harsh environments, inspect the switch for signs of wear, corrosion, or physical damage to the enclosure, handle, and internal components.
• Connection Integrity: With power disconnected, verify that all electrical connections are tight. Loose connections can lead to overheating and potential hazards.
• Cleaning: Keep the exterior of the enclosure clean and free from dust, dirt, and debris. Ensure ventilation openings (if any) are clear.
• Handle Operation: Periodically test the operating handle to ensure it moves freely and locks securely into both 'ON' and 'OFF' positions.

7. Troubleshooting

Refer to this section for common issues and their potential solutions:

• Switch Does Not Turn On:
  • Check the incoming power supply at the source.
  • Verify that the fuses are intact and not blown.
  • Ensure the operating handle is fully engaged in the 'ON' position.
• Switch Trips Frequently:
  • Investigate for overloads or short circuits in the connected load.
  • Ensure the connected load does not exceed the switch's 60 Amp rating.
• Loose Connections: If you suspect loose connections (e.g., flickering power, localized heat), disconnect power and have qualified personnel tighten all terminal screws.

If issues persist after troubleshooting, contact qualified electrical personnel or Schneider Electric support.
