Affinity LBD-200C-N1 Transmitter
Product Manual
of up to 95%, the equipment must be protected from conditions that cause condensation within
the equipment. The transmitter chassis requires a rack with a minimum of 24” vertical front-to-
rear rail separation. If a rear door must be used to secure the rack cabinet, the rack must be at
least 40” deep to accommodate transmitter cabling, and the door must open fully or be removed
to allow transmitter maintenance. If a rear door is placed on the rack, forced ventilation through
the cabinet is required (600 cfm minimum per transmitter is recommended) and an air or
temperature interlock should be incorporated for protection against interruption of ventilation
(contact Thales Broadcast & Multimedia Customer Service department for assistance). In case
of indoor installations, the area should be kept dry and clean. There should be sufficient space
in front of the transmitter cabinet for service personnel and test equipment. A minimum of 44”
behind the cabinet should be free for rear cabinet access and air movement. Also, ample room
must be available at the cabinet rear for cable placement.
