Note
Mounting the motor starter
You will find out how to mount the motor starter in chapter "Mounting/disassembly of

WARNING
Risk of injury from automatic restart
When you replace the motor starter, the motor starter can restart again autonomously if an
ON command is active. This can result in property damage or serious injury caused by
connected devices that are automatically started up.
Revoke the ON commands on the motor starter before replacing the motor starter.
CAUTION
Protection against electrostatic charge
When handling and installing the SIMATIC ET 200SP motor starter, ensure protection
against electrostatic charging of the components. Changes to the system configuration and
