Storage
The cabinet units must be stored in clean, dry rooms. Temperatures between -13 and +131
°F (-25 and +55 °C) are permissible (class 1K4 to IEC 60721-3-1). Temperature fluctuations
greater than 20 K per hour are not permitted.
If the cabinets are stored for a prolonged period, cover them or take other appropriate
measures to ensure that they do not become dirty and that they are protected against
environmental influences. If such measures are not taken, the warranty becomes invalid in
the event of a claim for damages.
NOTICE
Property damage to top hats caused by improper mechanical loading
The separately delivered top hats may be irreparably damaged if they are subjected to
mechanical loads before being installed on the cabinets.
