Festo – GDCP-CMMS-AS-G2-S1-EN – 1306NH – English 7
1 Safety and requirements for product use
1.1 Safety
1.1.1 General safety instructions
• In addition, always observe the general safety regulations for the CMMS-AS-...-G2.
The general safety regulations for the CMMS-AS-...-G2 can be found in the hardware doc-
umentation, GDCP-CMMS-AS-G2-HW-... Tab. 1, page 6.
Note
Loss of the safety function.
Non-observance of the environmental and connection conditions may lead to loss of the
safety function.
• Observe the specified environmental and connection conditions, in particular the
input voltage tolerances Technical data, Appendix A.1.
Note
Damage to the motor controller due to incorrect handling.
• Switch off the supply voltage before mounting and installation work. Switch on sup-
ply voltage only when mounting and installation work are completely finished.
• Observe the handling specifications for electrostatically sensitive devices.
1.1.2 Intended use
The motor controller CMMS-AS-...-G2 supports the following safety function:
– “Safe Torque Off” (STO) with category 3 / PL d in accordance with EN ISO 13849-1.
The motor controller CMMS-AS-...-G2 is a product with safety-relevant functions and is intended for
installation in machines or automation systems and for use as follows:
– in excellent technical condition,
– in original status without unauthorised modifications,
– within the product's limits as defined by the technical data Appendix A.1,
– within the specified service life of the switching elements Appendix A.1, Tab. A.6,
– in an industrial environment.

1 Safety and requirements for product use
8 Festo – GDCP-CMMS-AS-G2-S1-EN – 1306NH – English
Note
In the event of damage caused by unauthorised manipulation or other than intended
use, the guarantee is invalidated and the manufacturer is not liable for damages.
1.1.3 Foreseeable misuse
The following examples of foreseeable misuse do not belong to intended use:
– use outdoors,
– use in non-industrial areas (residential areas),
– use in applications where switching off can result in hazardous movements or conditions.
Note
– The STO function is insufficient as the sole safety function for drives subject to per-
manent torque or force (e. g. suspended loads).
– Bypassing of safety equipment is impermissible.
– Repairs to the motor controller are impermissible!
The STO (Safe Torque Off) function does not provide protection against electric shock,
only against hazardous movements!
Hardware documentation, GDCP-CMMS-AS-G2-HW-...
In applications with extremely high requirement rates, the service life of the switching elements must
be taken into account in the design (replacement interval for the motor controller)
Appendix A.1, Tab. A.1 and Tab. A.6.
1.1.4 Achievable safety level, safety function in accordance with EN ISO 13849-1
The motor controller CMMS-AS-...-G2 with integrated STO safety function fulfils the requirements of the
test regulations
– Category 3 / PL e in accordance with EN ISO 13849-1
and can be used in applications up to Cat. 3 / PL d in accordance with EN ISO 13849-1.
The achievable safety level depends on the other components used to achieve a safety function.

1.2 Requirements for product use
• Make this documentation available to the design engineer, installer and personnel responsible for
commissioning the machine or system in which this product is used.
• Make sure that the specifications of the documentation are always complied with. When so doing,
also take into account the documentation for the other components (e.g. motors, cables, etc.).
• Take into consideration the legal regulations applicable for the destination, as well as:
– regulations and standards,
– regulations of the testing organizations and insurers,
– national specifications.
• For emergency stop applications, protection against automatic restart corresponding to the re-
quired safety category must be furnished. Among other means, this can take place through an ex-
ternal safety switching device.
1.2.1 Technical requirements
General notes for the correct and safe use of the product, which must be observed at all times:
• Comply with the connection and environmental conditions of the motor controller (Appendix A.1)
and all connected components specified in the technical data.
Only compliance with the limit values or load limits will enable operation of the product in compli-
ance with the relevant safety regulations.
• Observe the instructions and warnings in this documentation.
1.2.2 Qualification of the specialists (requirements for the personnel)
The device may only be placed into operation by a qualified electrotechnician who is familiar with:
– the installation and operation of electrical control systems,
– the applicable regulations for operating safety-engineered systems,
– the applicable regulations for accident protection and occupational safety, and
– the documentation for the product.
1.2.3 Diagnostic coverage (DC)
Diagnostic coverage depends on the connection between the motor controller and the control loop
system as well as the implemented diagnostic measures Section 5.3.
If a potentially dangerous malfunction is recognised during the diagnostics, appropriate measures
must be taken to maintain the safety level.
Note
Check whether a fault exclusion of cross circuits in the input circuit and connection
wiring is possible in your application.
If not: If applicable, use a safety switching device with cross-circuit detection for control
of the safety function as well as an appropriate filter construction group for filtering the
test pulses at the control ports of the CMMS-AS-...-G2.
