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.

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
