E-STOP pushbutton connection
CAUTION!
With versions with integral E-STOP pushbutton, the E-STOP pushbutton
(terminals X1-10 to X1-13) must be integrated into the plant/machine's E-
STOP concept in accordance with EN/IEC 60204.

Enabling switch connection
Details of the pin assignment of the female 5-pin M12 connector for the enabling switch can
be found in the block diagram and the terminal configuration.
We recommend you use the PIT en1.0p-5m-s (order no. 401 110) as the enabling switch.

EMC requirements
Please note:
}
The power supply must meet the regulations for extra low voltages with protective sep-
aration (SELV, PELV).
}
The inputs and outputs of the safety switch must have a protective separation to
voltages over 60 V AC.
}
The supply voltage has to be at the safety switch terminals within the indicated toler-
ances (see Technical details).
}
the supply voltage of the safety switch must be secured with a fuse of type quick
between 2 A and 10 A.
}
The electrical installation must be performed in accordance with IEC/EN 60204.
}
The assured release distance (S
aO
) can be influenced by external influences (e.g.: tem-
perature, dirt, EMC) (see Technical details).
INFORMATION
Safety relays with a wide-range power supply or in AC device versions have
internal potential isolation and are not suitable as evaluation devices. Only
safety relays with a 24 VDC supply voltage are suitable.
