Failure to follow the directions and safety instructions given in this instructions
manual may result in serious hazards.
2.2 Intended use
The LM 20/ LM 16 module is used for ambient of fixed mounted loads in non-
hazardous environments in the ambient/application conditions defined chap.
3 "Technical data").
The modules are designed exclusively for the linear movement of payloads in
any position . The max. permissible payloads on the face plate:
LM 20: 2 to 8 kg, LM 25: 4 to 9 kg (chap. 3 “Technical data“).
The modules LM 20 and LM 25 can be used in combination with other modules
as a pick converted place station, whereby the permissible load capacity must
not be exceeded.
Any use beyond the described purpose is considered to be not in accordance
with the intended use.
The intended use of the module also includes:
▪observance of all instructions given in this instructions manual.
▪compliance with the inspection and maintenance work and the
specifications in the data sheets,
▪using only original spare parts.
2.3 Foreseeable misuse
Any use other than or beyond the intended use described above is considered
a misuse of the linear compensation.
Especially the following use is considered a misuse:
▪Use in potentially explosive atmospheres.
