2.2 Modifications by the user
The user must not make any modifications to the Schaeffler SmartCheck device. The user may only make settings
on the device itself or via the Schaeffler SmartWeb, Schaeffler SmartUtility Light or Schaeffler SmartUtility software.
The user bears responsibility for any further modifications! Should you detect a fault with your Schaeffler
SmartCheck device, please contact our Support team.
2.3 Technical data
·
The SmartCheck device must not be used in measurement voltage categories II, III or IV!
·
Cover any M12 connections that are not in use with the plugs supplied. This is the only
way to ensure that the degree of protection is maintained.
