5.1.2 Removing the contact protection
When the contact protection has been removed, the internal connections - with dan-
gerous voltage charges - are accessible.
Procedure
1. Press slightly on the two side snap closures and take the contact protection out of the
holder.
2. Use a voltage tester to check that all connections at the inverter and, if applicable, at
the I/O module, are de-energized.
