INFORMATION
This gives advice on applications and provides information on special fea
tures.
Intended use
The unit meets the requirements of EN 6094751, EN 602041 and VDE 01131. The con
tact expansion module is used to increase the number of instantaneous safety contacts
available on a base unit. Base units are all safety relays with feedback loop monitoring.
The category that can be achieved in accordance with EN ISO 138491 depends on the
category of the base unit. The contact expansion module may not exceed this.
The delayon deenergisation safety contacts may only be used up to max. PL d (Cat. 3).
For your safety
}
Only install and commission the unit if you have read and understood these operating
instructions and are familiar with the applicable regulations for health and safety at work
and accident prevention.
Ensure VDE and local regulations are met, especially those relating to safety.
}
Any guarantee is rendered invalid if the housing is opened or unauthorised modifica
tions are carried out.
}
Note for overvoltage category III: If voltages higher than low voltage (>50 VAC or >120
VDC) are present on the unit, connected control elements and sensors must have a
rated insulation voltage of at least 250 V.

Safety features
The unit meets the following safety requirements:
}
The contact expander module expands an existing circuit. As the output relays are
monitored via the base unit's feedback loop, the safety functions on the existing circuit
are transferred to the contact expander module.
}
The safety function remains effective in the case of a component failure.
