Fundamental 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.

• 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

Danger to life due to fire spreading if housing is inadequate

Fire and smoke development can cause severe personal injury or material damage.

• Install devices without a protective housing in a metal control cabinet (or protect the
