// HOW IT IS PROVEN //

Tested twice, before and after it is installed

Every board is tested at the factory before dispatch, then again on site once it is installed and terminated.

Factory acceptance testing

Each board is tested before it leaves the factory. Insulation resistance, primary and secondary injection, and functional checks against the schematic.
