Product description
CAUTION
Risk of damage to persons and property!
The voltage circuits on terminal XDN2 are
safely isolated from the mains circuit (safe
isolation in accordance with EN50178, PELV).
The requirements for safe isolation of

electric circuits must be observed if using
the connection options on this terminal.

DANGER
The user is responsible for determining the
necessity of an emergency OFF, its imple-
mentation, and the risk analysis! Make
sure the emergency OFF equipment is
accessible and effective. Release of the
emergency OFF equipment may not result
in an uncontrolled system restart!
Check the function of the emergency OFF
equipment before switching the system
on. If using the voltage circuits at the
emergency OFF terminal, observe the
requirements for the safe isolation of
electric circuits.
CAUTION
The user is obliged to maintain the
system-specific requirements for an
emergency OFF system.
When using external mains contactors in
superior emergency OFF circuits, observe
the restarting time of 10 seconds for
single switching and 30 seconds for
repeated switching.
