Total Access 6-Amp Rackmount PS/BC Scope of this Guide This guide contains important pre‐installation and installation instructions for installing the ADTRAN Total Access Rackmount 6‐Amp Power Supply Battery Charger (PS/BC, P/N 1180043L2). Craft personnel should review this entire guide as part of installation planning. In this Guide This guide contains the topics listed in Table 1. Table 1.
Total Access Rackmount 6-Amp PS/BC Installation and Maintenance Guide Introduction The PS/BC rectifier is part of the Total Access Rackmount AC Power Supply/Backup Battery System (APS/BBS). It is designed to work in conjunction with one or two ADTRAN backup battery packs (P/N 1175044L1). US E F Figure 1 illustrates the PS/BC (P/N 1180043L2) right and left side panels. Figure 1.
Description Description Originally designed for the Total Access 1500 system, the PS/BC can be used in any appli‐ cation using 120 VAC input, and requiring up to –54 VDC, 6‐amps output. In the Total Access 1500 configuration, the rectifier performs AC to DC conversion and, when used with the dual battery, provides up to eight hours of backup power for a fully populated Total Access 1500 bank (96 FXS circuits) with up to 50 percent off‐hook circuits at any one time.
Total Access Rackmount 6-Amp PS/BC Installation and Maintenance Guide Alarm Relays There are two uncommitted alarm relays associated with PS/BC operation, as follows: • AC Fail (ACF): Alarms if AC fails, the rectifier overloads, or the rectifier fails • Battery Low Voltage (BV): Alarms if either or both battery voltage drops below 42 VDC Fuse A standard 5×20 mm 5‐amp fuse adjacent to the AC power cord protects AC power feed overload in case of rectifier failure.
Installation Installation ! CAUTION CAUTION! SUBJECT TO ELECTROSTATIC DAMAGE OR DECREASE IN RELIABILITY. HANDLING PRECAUTIONS REQUIRED. Electrostatic discharge (ESD) can damage electronic modules. When handling modules, wear an antistatic discharge wrist strap to prevent damage to electronic components. Place modules in antistatic packing material when transporting or storing. When working on modules, always place them on an approved antistatic mat that is electrically grounded.
Total Access Rackmount 6-Amp PS/BC Installation and Maintenance Guide Mounting the PS/BC The PS/BC housing occupies a nominal area 15.35 inches (with mounting tabs) wide by 3.45 inches high and is designed so the four mounting tab screw holes align to threaded screw holes on the ADTRAN battery pack housing. This procedure assumes that the battery pack is mounted in the designated 19‐inch or 23‐inch rack. Hardware for mounting the PS/BC to the battery pack is included.
Installation Alternate Mounting There are two alternate mounting methods, as follows: 1.Mounting directly to a wall using customer‐supplied wood screws 2. Rack mounting (bracket), using on of the following kits: • 19‐Inch Rack Mount Kit, P/N 1175050L1 • 23‐Inch Rack Mount Kit, P/N 1175051L1 Rack Mounting Rack mounting kits can be purchased separately from ADTRAN. The rack mounting bracket mount location is normally at the battery position when batteries are mounted external to the cabinet.
Total Access Rackmount 6-Amp PS/BC Installation and Maintenance Guide Wiring Descriptions The wiring required for the single PS/BC and dual battery configuration is included. ! CAUTION All grounds must terminate at a known ground location. Check metal‐to‐ metal contact on all ground connections. Do not stack or combine grounds. Ensure ground circuit continuity. Ground A ground post adjacent to the PS/BC fuse is available for frame ground.
Wiring Descriptions A Load PS/BC A A PS/BC A Configuration I, Ia, Ib I. PS/BC, no battery. Ia. PS/BC + 1 battery string. Ib. PS/BC + 2 battery strings. B I Batt Ia Batt Ib Load B II PS/BC B II Configuration II, IIa, IIb, IIc, IId II. 2 PS/BC, no battery. IIa. 2 PS/BC + 1 battery string. IIb. 2 PS/BC + 2 battery strings. IIc. 2 PS/BC + 3 battery strings. IId. 2 PS/BC + 4 battery strings. This configuration shows adding battery strings alternately to PS/BC A and B.
Total Access Rackmount 6-Amp PS/BC Installation and Maintenance Guide To prevent heat buildup the battery charge current is limited to 1 amp per battery. This elimi‐ nates the need for temperature compensation. Alarm Wiring The alarm relay output originates at a modular connector with a 6‐foot wire stub. Wiring termination of the output is customer designated.
Operation Operation The PS/BC starts operation when AC or battery power is applied. During operation ambient temperature can increase up to 50°C without affecting output. If ambient temperature increases beyond 50°C, output must be de‐rated. At 70°C ambient, output load is limited to 5 amps. ! CAUTION External PS/BC surfaces can become hot during operation above 50°C ambient temperature.
Total Access Rackmount 6-Amp PS/BC Installation and Maintenance Guide Maintenance The Total Access PS/BC does not require routine maintenance for normal operation. ADTRAN does not recommend that repairs be attempted in the field. Repair services may be obtained by returning the defective unit to ADTRAN. Refer to “Appendix A, Warranty” for further information. Fuse If the fuse fails, replace with a fuse of identical type and rating.
Specifications Specifications Power Factor specifications for the Total Access PS/BC are listed in Table 3. PS/BC specifica‐ tions are listed in Table 4. Table 3. Power Factor and Efficiency Power Output vs. Efficiency Power Output Power Factor Efficiency Power Dissipation 50 watts > 98% > 81% 11 watts 150 watts > 99% > 89% 18 watts 325 watts > 99% > 91% 29 watts Table 4.
