5 Electrical installation
Pin Name Specification
1 STOA Control input A for the STO function
2 GNDA Reference potential for STOA
3 STOB Control input B for the STO function
4 GNDB Reference potential for STOB
5 DIN6 Digital input 6 (limit switch 0)
6 DIN7 Digital input 7 (limit switch 1)
7 24 V 24 V supply
8 GND Reference potential for 24 V supply
For wiring the 24 V supply, be sure to also observe the instructions in section 5.3
Connector BL 4100-M / BL 4100-D: Power supply [X9] on page 30 or in section 5.4
Connector BL 4800-M / BL 4800-D: Power supply [X9] on page 33.
To ensure the STO ("Safe Torque Off") function, the control inputs STOA and STOB must
be connected in a dual-channel manner with parallel wiring. See section
Safe torque off
(STO) in the Product manual smartServo BL 4000-D / smartServo BL 4000-M. This type of
connection can be part of an emergency stop circuit or safety door setup, for example.

Cable cross-section (flexible conductors, wire end sleeve with
insulating collar), one conductor 0.25 mm²… 0.5 mm²
Minimum wiring for commissioning [X3]
Danger to life due to bypassed safety functions
Safety functions must never be bypassed.
For the commissioning of the system without any safety systems, STOA and STOB can
be connected to the 24 V supply and GNDA and GNDB can be connected to GND in a
fixed manner.
Perform the minimum wiring of the inputs STOA/STOB and GNDA/GNDB for the
commissioning process in such a way that it must be removed when the final safety wiring
is performed.
