Pre-Initial Power-up Tests
Introduction
The following information is used to check for any electrical short
circuits and to verify the operation and tolerances of each frame at the
site before applying power for the first time. It contains instructional
information on the proper initial power up procedures for the SC4812T
Lite stand–alone and expansion frames for both the North American
version and the International version. If directions are different for either
version, they are called out within the procedure. Please pay attention to
all cautions and warning statements in order to prevent accidental injury
to personnel.
NOTE
Unless otherwise noted, all procedures in this section are to be
followed for each frame at a site.
Required Tools
The following tools are used in the procedures.
S Clamp–on DC current probe (600 A capability with jaw size to
accommodate 2/0 cable).
S Digital Multimeter (DMM) with standard 2mm (.080”) tip probes
S Hot Air Gun – (optional for part of the Alarm Verification)
Cabling Inspection
Using the site-specific documentation generated by Motorola Systems
Engineering, verify that the following cable systems are properly
connected:
S Receive RF cabling – up to six RX cables
S Transmit RF cabling – up to six TX cables
S For expansion frame installations, inter–frame RX diversity cabling –
six RX cables
NOTE
For DC power applications (+27 V):
S The positive power cable is red.
S The negative power cable is black. (The black power cable is
at ground potential.)
Initial Inspection and Setup
Table 2-2: Initial Inspection and Setup
Step Action
1 Be sure that the facility circuit breaker controlling external AC power supplied to the frame is set to
OFF.
2 Verify that the external AC power supply is correctly connected to the ACLC input by performing the
procedure in Table 2-4.
DC Power System Pre-power Application Test
Before applying any power to the BTS frame, follow the procedure in
Table 2-3 to verify there are no shorts in the DC power distribution
system.
