Severity level 1
3)
1) Rated load = tool load (gripper finger) + payload
2) Low corrosion stress. Dry internal use or transport and storage protection. Also applies to parts behind
covers in non­visible interior areas, and parts which are covered in the application (e.g. drive trunnions).
3) Specification for vibration and shock resistance applies to the product with rigid mounting kit; mounting
kit with Z­neutralisation is not included.
