2. Analog Input Configuration

The current and voltage sensor inputs are illustrated below.

These inputs are protected against electrostatic discharge through clamping

diodes, in conjunction with the amplifiers input configuration.

The feedback loops from the outputs of the amplifiers A and A generate virtual
