Notes
Voltage!
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.
Highest current carrying capacity of supply
contacts is 4 A!
NOTICE
Observe the maximum current carrying capacity per supply line (U
LS
, U
A
) as
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.
Open connections!
NOTICE
If connections have not been closed with protective covers, liquid or dirt can
penetrate the IndraControl S67 components and destroy them. Protect all
non-required connections with protective caps to be ordered separately (see
chapter 12.9 "Protective caps" on page 131
) 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 such a case, replace the field bus coupler.
Tightening torques for connectors are: 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 12.5 "Ready-made Sercos III Cables" on page 128
)
●
When laying the cables, ensure not to lay cables in shear areas of mov‐
ing machine parts
●
Connect the cable shield of the field bus cable to the functional ground
at both ends across a wide area.
●
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.
