cable shields.
• As a minimum, connect cable shields and the cores of cables that are not used at one
Danger to life due to electric shock when not grounded
For missing or incorrectly implemented protective conductor connection for devices with
protection class I, high voltages can be present at open, exposed parts, which when
touched, can result in death or severe injury.
• Ground the device in compliance with the applicable regulations.
Danger to life due to electric shock when opening plug connections in operation
