10. INCORPORATION INTO 19" FLIGHTCASES OR 19" RACK SYSTEMS
Note Do not operate the DPA 4410 without its enclosure or without parts of the enclosure.
When incorporating the DPA 4410 into a 19" flightcase or 19" rack system make sure, that there is sufficient
air-flow. Between the amplifier’s rear plate and the back-wall of the surrounding enclosure there has to
be at least a space of 60 mm x 330 mm up to the enclosures ventilation gaps. Above the rack system
should be at least a space of 100 mm for a sufficient circulation of the air. During the operation of the DPA
4410 the environmental temperature within the rack closet may increase by about 10° C. This has to be
taken into consideration when installing other equipment into the same rack system or other enclosures.
Note For trouble-free operation of the appliance, the maximum environmental temperature should
not exceed +40° C.
