Safety Instructions
Use only the components and tools specified by Stäubli. Do not deviate from the preparation and assembly instructions as stated herein, otherwise Stäubli cannot give any guarantee as to safety or conformity with the technical data. Do not modify the product in any way.
Connectors not originally manufactured by Stäubli which can be mated with Stäubli elements and in some cases are even described as "Stäubli-compatible" by certain manufacturers do not conform to the requirements for safe electrical connection with long-term stability, and for safety reasons must not be plugged together with Stäubli elements. Stäubli therefore does not accept any liability for any damages resulting from mating such connectors (i.e. lacking Stäubli approval) with Stäubli elements.
Stäubli Electrical Connectors (Stäubli) does not accept any liability in the event of failure to observe these warnings.
Installation, electro technical expertise
The products may be assembled and installed by electrically skilled or instructed persons duly observing all applicable safety regulations.
Caution, risk of electric shock
Work in a de-energized state. Follow the five safety rules when working on electrical installations. After the respective electrical installations have been identified, the following five essential requirements shall be undertaken in the specified order unless there are essential reasons for doing otherwise:
- Disconnect completely;
- Secure against re-connection;
- Verify absence of operating voltage;
- Carry out grounding and short-circuiting;
- Provide protection against adjacent live parts.
Any person engaged in this work activity shall be electrically skilled or instructed, or shall be supervised by such a person. Source: EN 50110-1:2013.
Protection against electric shock shall be checked in the end-use applications too.
Caution
Each time the connector is used, it should previously be inspected for external defects (particularly the insulation). If there are any safety concerns, a specialist must be consulted or the connector must be replaced.
Useful hint or tip: For further technical data please see the product catalog, www.staubli.com/electrical.
