P8 - ISO 13849 Safety Circuit (Option)
STOP!
BEFORE using P8, read the COMPLETE DETAILED INSTRUCTIONS for the ISO 13849-1 Safety Circuit in Section 4.1.8 of
manual S94H201 (PositionServo Users Manual on the accompanying CD and www.lenzeamericas.com).
If installed, the ISO 13849-1 Safety Circuit connector, P8, is located on the bottom of the PositionServo. P8, a 6-pin
quick-connect terminal block. This option provides additional inputs to disable the drive output so that the drive
cannot cause torque to be generated in the motor. This safety function known as “Safe Torque Off” meets the
requirements of the following standard: ISO 13849-1 Safety of Machinery, Safety-related Parts of Control Systems,
Category (Cat.) 3, Performance Level (PL) d and Safety Integrity Level (SIL) 2, per EN 61800-5-2 2007.

WARNING!
The drive is supplied from the factory with the ISO 13849-1 safety circuit enabled. The drive is not operational until +24V
is present at terminals 4 and 6. For the proper safety connections, refer to the “Connection of Two Safety Circuits with
Ex24V Supply” diagram. Under certain applications when safety connections are not required the drive may be
operated with the safety circuit disabled. The diagram below illustrates how to bypass the safety circuit.

*1 – This voltage must under no circumstances be used to supply the ISO 13849-1 Safety circuits (terminals 3 to 6). This voltage is intending only for use in bypassing
(disabling) the ISO 13849-1 circuits should they not be required.
*2 – A Se24VDC supply providing reinforced isolation (SELV or PELV), must be supplied to operate these inputs. This supply should not be floating but should
be referenced within 20V peak of PE at the drive.
WARNING!
It is required that all information contained within this ISO 13849-1 standard be observed when implementing any
part of this safety circuit functionality with the PositionServo drive.
