Safety information
1.1 General safety instructions
Danger to life through a hazardous voltage when connecting an unsuitable power supply
Death or serious injury can result when live parts are touched in the event of a fault.
• Only use power supplies that provide SELV (Safety Extra Low Voltage) or PELV-
Danger to life when live parts are touched on damaged devices
Improper handling of devices can cause damage.
Hazardous voltages can be present at the housing or exposed components on damaged
devices.
• Ensure compliance with the limit values specified in the technical data during transport,
• Do not use any damaged devices.
Danger to life through electric shock due to unconnected cable shields
Hazardous touch voltages can occur through capacitive cross-coupling due to unconnected
cable shields.
• Connect cable shields and unused conductors of power cables (e.g., brake conductors)
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.
