* **Grounding:** Ensure proper power line ground connection to the input terminal. All power ground lines to application and maintenance equipment must be properly grounded.
* **Electrical Shock Risk:** Avoid touching any electrical circuits, even when power is off, as capacitors may retain a charge. Use safety glasses during open-cover checks.
* **Output Labeling:** The user must ensure output power and sense lines are properly labeled regarding safety hazards to eliminate inadvertent contact with hazardous voltages.
