described in this section. Always adhere to the prescribed sequence.
Danger to life due to electric shock from destruction of the measuring device
due to overvoltage
Overvoltage can damage a measuring device and result in voltage being present in the
enclosure of the measuring device. Touching the live enclosure of the measuring device results in
death or lethal injuries due to electric shock.
• Only use measuring devices with a DC input voltage range of 1100 V or higher.
Procedure:
1. Disconnect the AC circuit breaker and secure it against reconnection.
