Installation Instructions:
The IGA TEST series protectors must be installed in series with the low voltage line, positioned between the power control circuit breaker (ICP) and the residual current device (ID). Installation should occur without power running through the line. Protective coils are to be placed between the lines connected to the residual current breaker and the neutral. The protectors cut off the power supply upon detecting a permanent overvoltage, safeguarding downstream equipment. To restore the main circuit breaker, the protective coils must be reconnected using the RESET buttons, starting from the most external coil.

Compatibility:
IGA TEST protectors can be used alongside ATSUB-D transient overvoltage protectors.
