Using Feedback-Free Module in Safety Applications
12.3 General Measures and Requirements for the Module Supply
Concept
Rexroth IndraControl S67 Digital Module 8 Outputs – 2.0 A (4×M12)
NOTICE
Prevent conductive dirt in the sockets of the supply voltage connections for
the voltages U and U by appropriate measures. Before establishing a con‐
A LS
nection, verify that the contact areas are free from dirt and foreign particles.
Only use clean tools and materials when handling modules.
NOTICE
Tighten the connectors with a torque of 0.6 Nm to reach the degree of protec‐
tion IP 67. Otherwise, safe switching-off of the I/O module by a safety control
device cannot be ensured in case of penetrating dirt.
NOTICE
The values in the specification of the connection lines regarding the environ‐
mental properties and the mechanical load must never be exceeded.
WARNING
The safety control device has to be able to detect if an external voltage is fed
in (e.g. due to a line short circuit) causing the loss of the safety function.
NOTICE
If no ready-made Bosch Rexroth cables are used, fanning out strands when
connecting wire ends to connectors has to be prevented. Sporadically, a
short circuit in the connectors can result in the loss of the safety function. If
required, check the wire insulation, e.g. by using a high voltage test.
