Requirements for isolating transformers
` An earthed star point must be available on the secondary side. The
star point on the secondary side must be earthed and must be con-

prevent overvoltages between the external conductors and the servo
amplifier housing.
` The isolating transformers must have the relevant input and output
voltages.
The following illustration shows the connection types.
