Basic safety instructions
1.1 General safety instructions
Danger to life when live parts are touched on damaged devices
Improper handling of devices can cause damage.
For damaged devices, hazardous voltages can be present at the enclosure or at exposed
components; if touched, this can result in death or severe injury.
• 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.
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 voltage-free 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 connection,
• Check all power connections at regular intervals. This applies in particular after
