Note
The quantitative assessment of the emergency stop safety function must be based on the
B
10d
values corresponding to the used standards (e.g. ISO 13849-1) under consideration of
the respective application (frequency of the actuation, service life, diagnostics by the evaluation
unit, etc.). The B
10d
values only apply when the technical properties of the emergency stop
button are taken into account.

WARNING
Electric shock due to connection of an unsuitable power supply
When equipment is connected to an unsuitable power supply and/or insufficiently grounded
or rear cover (Page 35), exposed components may carry a hazardous voltage that might
result in serious injury or death.
● Only use power supplies that provide SELV (Safety Extra Low Voltage) or PELV
(Protective Extra Low Voltage) output voltages acc. to UL 61010 for all connections and
terminals of the electronics modules.
