INSTALLATION            INSTRUCTIONS

It is important to make a low inductive ground connection.

The output shield must be connected to the high voltage potential (kathode potential of the thyristor)

It is recommended to make a connection between the negative input voltage and ground. 

The environment must be clean and dry. Excessive temperature should be avoided.
