Improper handling of devices can cause damage.
● Ensure compliance with the limit values specified in the technical data during
transport, storage and operation.
● Do not use any damaged devices.
DANGER
Danger to life due to electric shock when device is 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
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 been explicitly stated that they can be opened in operation.
3.5.2 Dangers posed by moving parts
DANGER
Danger to life due to unexpected movement of machines when using mobile
wireless devices or mobile phones!
Using mobile radios or mobile phones with a transmit power > 1 W closer than
approx. 2 m to the components may cause the devices to malfunction in such a
way as to influence the functional safety of machines and therefore place people
at risk or cause property damage.
● Switch off radio units and mobile phones in the direct vicinity of the
components.
