How to use
Install the isolation switch in accordance with applicable electrical codes and the enclosure manufacturer’s instructions. Connect each phase conductor to the appropriate terminal and secure the protective covers after wiring. To isolate the circuit, operate the manual handle to the OFF position until the visual indicator confirms open contacts on all phases.

After work, return the handle to the ON position and confirm correct restoration of supply and protective functions.
Usage recommendations
Before installation or maintenance, always de-energise upstream equipment and follow lockout/tagout procedures. Use appropriate personal protective equipment and voltage testing tools to confirm de-energisation. Ensure terminal connections are tightened to recommended torque values and periodically inspect the switch for signs of wear, corrosion or mechanical damage.
