2 General information

DANGER!

Do not operate with a defective power supply unit!

In this case, potentially fatal excess voltage may occur at the sockets of the
device!

DANGER!

The device is not suitable for safety applications, emergency off equipment,
or applications in which a malfunction could lead to injuries and material
damage.

Failure to observe this note may lead to serious damage to health and mate-
rial damage!

DANGER!

This  device  must  not  be  used  in  a  potentially explosive environment. If the
device is operated in a potentially explosive environment, there is an
increased hazard of deflagration, fire, or explosion due to formation of sparks!

NOTE!

The function and operational safety of the device can only be maintained
under the climatic conditions specified in chapter Chapter 11 "Technical
data", page 40.

If the device is transported from a cold environment to a warm environment,
the device may malfunction due to condensate formation. In this case, it is
necessary to wait for the device temperature to align with the room tempera-
ture prior to startup.

NOTE!

When connecting to other devices, take particular care in planning the wiring.
Under certain circumstances, internal connections in third-party devices (e.g.
connection of GND to ground) may lead to impermissible voltage potentials
that can cause impaired function or even destruction of the device itself or a
connected device.

NOTE!

Please do not connect any devices to socket 1 (see Chapter 4.3 "Con-
nections", page 12)!
