Notes

WARNING
Operate IndraControl S67 components exclusively with DC 24 V PELV (pro‐
tective extra-low voltage) or SELV (safety extra-low voltage) voltage sources.
Non-compliance can result in electric shock.
NOTICE
Observe the maximum current carrying capacity per supply line (U
well as the total current consumption for all IndraControl S67 components.
Both values must not exceed 4 A, as an increase in current causes the con‐
tacts to overheat and damages the IndraControl S67 components.
NOTICE
If connections are not closed with protective caps, liquid or dirt can enter and
thus destroy the S67-DO8-M12-2A module. Protect all connections that are
not required with protective caps to comply with protection class IP 67.
● The male connectors must be disconnected from the power supply be‐
fore screws are tightened.
● Tighten the male connectors only by hand. Using mechanical tools can
cause the threads to strip. In this case, the S67-DO8-M12-2A module
has to be replaced
Tightening torques for male connectors are:
– Actuator connections, M12: 0.4 – 0.5 Nm
– S-BUS and supply connections, M12: 0.6 Nm
● Check the exact positioning (coding) between plug and socket
● Use only ready-made Bosch Rexroth system cables to transmit the pow‐
er supply and for the S-BUS. This achieves the specified characteristic
values of technical data.
● Keep sufficient distance between all cables and electromagnetic inter‐
ference sources to achieve a high noise immunity of the IndraControl
S67 system against electromagnetic emissions.
● Note the minimum bending radius of Bosch Rexroth system cables (see
chapter 13 "Accessories" on page
● When laying the cables, ensure not to lay cables in shear areas of mov‐
ing machine parts
● Ensure the correct layout of the potential equalization
● Do not use drop stubs, as increased line reflections and signal distor‐
tions are caused! This worsens the transmission properties significantly.
