Fundamental safety instructions
2.1 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.
● As a minimum, connect cable shields and the conductors of power cables that are not
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

capacitors
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 injury.
● Wait for 5 minutes before you check that the unit really is in a no-voltage condition and
