- Must be installed and maintained by qualified personnel; power off and test for voltage before disassembly.
- Secondary circuit work of the current transformer must short-circuit the secondary winding to prevent an open circuit.
- Restore mechanical components and doors before powering on; violation may cause electric shock, fire, or explosion.
