exposed components.
• Ensure compliance with the limit values specified in the technical data during transport,
• Do not use any damaged motors/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.
• 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
When opening plug connections in operation, arcs can result in severe injury or death.
• Only open plug connections when the equipment is in a no-voltage state, unless it has
NOTICE
Material damage due to loose power connections
Insufficient tightening torques or vibrations can result in loose electrical connections. This
can result in damage due to fire, device defects or malfunctions.
• Tighten all power connections with the specified tightening torques, e.g. line supply
• Check all power connections at regular intervals. This applies in particular after
