Interfaces for automation
CAUTION
Damage to the machine due to improper connection!
Unsuitable control leads or incorrect connection of input and output signals can cause
damage to the machine.
• Only use shielded control leads!
• If the machine is to be operated with control voltages connection via suitable isolation
amplifiers is required!
• To control the main or secondary current via control voltages, the relevant inputs must be
enabled (see specification for activation of control voltage).
