Principle Cabinet Design EMC and grounding G574e Part 3
This slide should explain groundings inside cabinets with different cabinet surfaces.
The base station power cabinet is a key equipment ensuring continuous power supply to base station devices, with LLVD (Load Low Voltage Disconnect) and BLVD (Battery Low Voltage Disconnect) being two important protection mechanisms in the power cabinet.
Minimum clearances must be maintained between the cabinets and surrounding building parts/cabinet to accommodate the installation and maintenance of the base station. The following constraints must be considered for cabinet clearances:
Page 58 8.4 Routine Maintenance The routine maintenance of the 3900 series GU co-cabinet base stations are performed separately on the GBTS part and NodeB part. The routine maintenance procedure is the same as that for the corresponding single-standard base station.
The battery cabinet must be installed adjacent to the power cabinet. The following diagram shows the equipment layout for a typical new indoor Macrocell site. Notes: The cabinets may be placed with zero clearance to the rear wall. The cabinets may be placed with zero clearance to the side wall, however some clearance is recommended.
