6.2 Maintenance services
Before delivery, each HV DTemp-P central unit is subjected to a functional test. In addition,
a test certificate (HV insulation test) is issued for each central unit. This is documented by
the stickers "Function tested" and "HV insulation test" which are attached to the rear side
of the module housing.
To ensure reliability and functionality, a measurement module should be checked at least
every 12 months. CSM offers maintenance packages and a repair service for this purpose.
