1 Safety notes
17.12.2018
To ensure safety and reliability of the LMV27, the following points must also be
observed:
Condensation and ingress of humidity must be avoided. Should such conditions
occur, make sure that the unit will be completely dry before switching on again!
Static charges must be avoided since they can damage the unit’s electronic
components when touched.
Recommendation:
Use ESD equipment
If the unit fuse was blown due to overload or a short-circuit at the connection
terminals, the LMV27 must be replaced since the switching contacts might have
been damaged
If error codes 95…98 appear during operation, this may be an indication of contact
problems and the LMV27 should be replaced
1.2 Mounting
notes
Ensure that the relevant national safety regulations and standard notes are
complied with
In geographical areas where DIN regulations are in use, the requirements of VDE
must be satisfied, especially DIN / VDE 0100, 0550 and DIN / VDE 0722
The LMV27 must be secured with fixing screws M4 (UNC32) or M5 (UNC24),
observing a maximum tightening torque of 1.8 Nm and using all 4 fixing points. The
additional mounting surfaces on the housing are provided to improve mechanical
stability. These must fully rest on the mounting surface to which the unit is secured.
The flatness of that mounting surface must be within a tolerance band of 0.3 mm
