1.2 Electrical Safety
High Voltage

The high voltage power supply provides power for the device operation. Direct or indirect
contact with high voltage power sources may result in fatal injury.

Non-standard or incorrect high voltage operations may result in fire and electric shocks.

The personnel who install the high voltage facility must be qualified to perform high
voltage operations.

When selecting, connecting, and routing power cables, ensure compliance with local
laws and regulations.

Before connecting cables to the SmartLi, ensure that the power distribution switches are
turned off.

Use only dedicated tools during high voltage operations.
