1X SC480 BTS Hardware Installation, Optimization/ATP, and FRU
DRAFT
Objective
The objective of this procedure is to install the AC power cabling and
Battery Backup input cables to the Power Distribution Enclosure (PDE).
This equipment uses dangerous voltages and is capable of
causing death. Use extreme caution when handling and
testing this equipment.
Earth connection is essential before connecting the power
due to the presence of high earth leakage current.
CAUTION
AC Cable Description
The Power Distribution Enclosure (PDE) is UL rated at 14
Amperes, in the range 200–240 VAC. The Customer Site
installation must provide a disconnect device and over
current protection device. A breaker size of 25 Amperes is
recommended or as appropriate by local electrical code.
The frame can accommodate an AC conductor range of 6
AWG to 12 AWG, as limited by the internal AC terminal
block. Cable sizing should be determined by Local
Electrical Codes, using 90C min rated conductors, with
derating for 50C operation. Motorola recommends not less
than 10AWG copper for buried/raceway cables.
NOTE
The cables listed in Table 4-29 are recommended for this installation.
However, consult the manufacturer’s installation guide for further
information.
