Safety information
1.1 General safety instructions
Electric shock due to equipment damage
Improper handling may cause damage to equipment. 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.
Electric shock due to unconnected cable shield
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)
Electric shock if there is no ground connection
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.
Arcing when a plug connection is opened during operation
Opening a plug connection when a system is in operation can result in arcing that may
cause serious injury or death.
• Only open plug connections when the equipment is in a voltage-free state, unless it has

Property damage due to loose power connections
Insufficient tightening torques or vibration can result in loose power connections. This can
result in damage due to fire, device defects or malfunctions.
• Tighten all power connections to the prescribed torque.
• Check all power connections at regular intervals, particularly after equipment has been
