INSTALLATION            INSTRUCTIONS

It is important to make a low inductive ground connection.

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

The output lines are not insulated for high voltage. Therefore they must be mounted insulated with a minimum distance of 50 mm to other metallic surfaces.. 

Due to electrical fields the body of the power supply must have a free distance of 25 mm around. If several power supplies are mounted, a grid of 130 mm is recommended.

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