Objective
T ask 16 is performed for 220 V AC UBS Macro BTS only .
The objective of this procedure is to perform T ask 16, which includes:
• A ttaching customer supplied wiring and conduit for 220 V AC lines.
• Connecting wires and required insertion bridges to the AC INP UT terminal block on the
rear of the AC PSM shelf .
• Routing the loose ends of the wires to the site 220 V AC source for connection to the source.
V erify that the +27 V DC output power cable from the PSM shelf is already
connected to the PDU +27 V DC input power cable. This was performed during
T asks 4 -7.
Frame AC power cables and wiring information
The AC PSM shelf and AC PSMs can operate with the following AC power inputs:
• Input AC V oltage R ange: 154 V AC to 300 V AC
• Single -Phase
• 3 -Phase ST AR
• 3 -Phase DEL T A
Consider the following AC power input circuit characteristics:
• The AC PSM shelf terminal block has seven terminals; one for Ground plus six for AC
line wires and insertion bridges.
• The AC PSM shelf terminal block Ground terminal can accommodate a wire size range of
2 A WG to 10 A WG .
• The AC PSM shelf terminal block AC line terminals can accommodate a wire size range of
2 A WG to 10 A WG .
