Installation Guidelines

• Ensure the power supply is completely isolated and locked out before attempting installation or maintenance.
• Mount the switch in an appropriate enclosure that provides sufficient protection against environmental contaminants and accidental contact.
• Verify that all electrical connections are tightened to the manufacturer's specified torque values to prevent overheating.
• Ensure adequate clearance around the switch to allow for heat dissipation and safe operation of the handle mechanism.
• Use appropriate wire gauges and terminal lugs compatible with the 400 A rating of the device.
• Always verify that the installed Class J fuses match the circuit requirements and the switch ratings.
