Conditions for transport, storage and installation
If the ambient conditions for transport, storage or switch-
board installation deviate from the normal service condi-
tions listed in Tab. 8/4 (for example an excessively low or
high value for temperature or air humidity), the measures
required for proper treatment of the switchboard must be
agreed upon between manufacturer and client.
