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-

nected to the servo amplifier's protective earth conductor. This will

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.
