MM22315, Rev. 8 4, INSTALLATION The MARTS 111 PSI03010 series Switching Power Supply is designed for MARTS 11 stations with 26VDC Power amplifiers, Before installation verify that the station's RF Power Amplifier is designed to operate with a nominal 24VDC power supply. Figure 4-1, Figure 4-2, and Figure 4-3 show the front and rear panel views of PS103010V120 and PS103010V240. The power supplies are identical in design, with exception of the front panel service receptacles found only on the PS103010V 120.
MM22315, Rev, B A —— a 41 INSTALLATION PREPARATION Installation and service is simplified through the use of connectors and common hardware components. During installation L-Brackets arc installed to support the rear of the Switching Power Supply, FM103177V1 brackets are used to support the supply in 69” and 83" indoor cabinets, and the Open Rack.
MM22315, Rev. B 4.2 4.3 RACK LOCATION When locating new equipment in rack mount assemblies it is important 10 follow all specified installation procedures to achieve proper air flow, wiring shames requirements, and maintain system integrity. Figure 4-6 provides rack mounting information to be followed when replacing the 19A149979P1 power supply with a PS103010V120 Switching Power Supply. The new supply should be mounted to the upper most rack position in the cabinet or open rail station.
.4 4.5 4.6 MM22315, Rev. B Once the Power Supply is mounted, it may be difficult lo access the rear panel connections. Ensure that all connections are secure prior to mounting the power NOTE supply.
AM22315, Rev. B 14 A potentiate for adjusting the float voltage of the battery charging circuit is accessible through an opening in the top cover of the power supply assembly. Adjustments should only be made in accordance with the data supplied by the battery manufacturer. Damage may occur if the float voltage is not set per the battery’s manufacturer specifications, Damage may occur if the float voltage is not set per the battery's manufacturer specifications. DO NOT set the battery Moat voltage above 26.
MM22318, Rev. 8 52 18 5.1.3 Status Signaling (Alarm Output) Power supply provides a status indicator output. In the event of an AC power or fan failure this out pm can be used te provide signaling to alarm or status inputs within the MARTS 111 Base station. This output is designed to provide a positive feedback loop for alarm inputs. An Alarm status condition could also be generated by a loss of loop (wiring connections). This status indicator output monitors both the AC input and fan status.
