Safety instructions

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

Electric shock due to residual charges in power components

Because of the capacitors, a hazardous voltage is present for up to 5 minutes after the

power supply has been switched off. Contact with live parts can result in death or serious

• Wait for 5 minutes before you check that the unit really is in a no-voltage condition and
