6.4.3. Limiting through currents

Inside E20-10 circuits AGND, GND, GND*, presenting on module connectors are
interlinked (p. 6.5.3). This places certain restrictions on maximum permissible through currents
through circuits AGND-GND-GND*.
Attention! Maximum permissible through currents exceeding can cause E20-10failure.
AGND-GND
AGND-GND*
