2 Introduction 2.1. General Information DC Power Plants from APC have unique features that make them easy to install, maintain, and upgrade. The rectifier units are modular and truly “hot-pluggable” into the shelf assembly without any separate AC wiring. The MX06 50 has 1 shelf, holding five rectifiers for a maximum of 52.5 Amps. The MX06 100 has 2 shelves, holding ten rectifiers for a maximum of 105 Amps. The controller provides monitoring and control functions for each component

3 Installation 3.1. Unpacking Equipment Remove equipment from packing material and inspect for shipping damage or missing items. It is important to report damage or material shortages to the shipping carrier while a representative is on site. If concealed damage or material shortages are found at a later time, contact the shipper to make arrangements for inspection and claim filing. Refer to Section 7 in the event it is necessary to return equipment to APC. CAUTION: Approp

Ventilation The rectifier modules for this system have fans that provide front-to-rear airflow for internal cooling. The power system housing should be mounted such that there is free airflow to the front and back of the unit. [Refer to Section 6.5 for environmental characteristics.] Free airflow should be ensured so that the power system can provide full power at a given ambient temperature without de-rating. 3.3. AC Power Connections WARNING: Ensure that all of the external DC

3.4. Battery Connections WARNING: Hazardous energy levels are present on bare conductors in the -48VDC distribution connection area of the plant. Accidental shorting of distribution conductors can cause arcing and high currents that can cause serious burns or other physical harm. It is recommended that: • Remove any jewelry, rings or watches while working on this equipment. • Use insulated wrenches, screwdrivers, cutters, pliers and other tools.

Battery Temperature Probe Installation The 15 Ft (4.5m) temperature probe is used to monitor the battery string temperature. To get the most representative temperature measurement, the probe should be placed in contact with a battery cell that is centrally located. The probe should be placed directly in contact with the cell (not the frame surrounding the cell). Generally, the cell cover can be used; be careful not to allow the probe body to touch the terminals. Plug the connector end

3.6. Load Protection Installation Circuit Breaker Installation Standard circuit breaker output boards are available with two 30 Amp breakers or one 60 Amp breaker. Output boards are installed at the factory and are not field replaceable units. Contact APC if the output configuration is not suitable for your needs. Other breaker sizes are not available. GMT Fuse Installation Fuse holders that accommodate GMT fuses are located on the front panel on the left side of the unit. In

3.7. Load Connections Cable Size Considerations The DC load cable(s) should be sized to limit the voltage drop from the DC power plant to the loads per system design requirements. The cable(s) must also carry the full load current during battery operation. During battery operation the voltage will be lower and for constant power loads, the current will typically be higher. If assistance is required to determine the necessary cables for the application, contact your sales representa

3.9. Rectifier Module Installation WARNING: Rectifier DC output circuits will be damaged if battery is installed incorrectly. Before rectifier installation, ensure proper battery polarity and that the battery is isolated from the rest of the system The rectifier modules are generally shipped in separate containers. Follow the procedure below to install a rectifier module. Rectifiers may be installed even when the system is energized. 1) Remove the cover plate (if presen

5) Use a Digital voltmeter to measure the system voltage using the “RTN” (+) and ”-NEG V” (-) test points on the front panel. The voltage is set at the factory for –54.0 V dc. Use the “V ADJ” potentiometer to set the voltage to the desired level. 3.11. Battery and Load Power up After the initial checkout has been performed, the following steps are followed to complete the system power up procedure. 1) Turn on the external circuit breaker from the battery to the power plant.
