Outdoor cabinet doors and lid
Door function
The doors have the following functions:
 Provide physical security and environmental protection.
 Assist in correct thermal management by ducting return airflow.
 Provide EMC shielding.
The door wind stops enable the doors to to be latched open at the 90° or 120°
position. The power supply enclosure door, when closed, overlaps the radio
enclosure door. The doors also overlap the TMS front cover and the latches of
the lid. The power supply enclosure door therefore provides the single locking
point for the cabinet and has the striker for the door open alarm microswitch.
NOTE
When the Horizon macro outdoor is delivered, the keys for
the door are contained in a plastic bag, fastened to the
front grille of the TMS.
