2.4.Battery Connections
WARNING: Hazardous energy levels are present on bare conductors in the DC 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 to:
Remove any jewelry, rings, or watches while working on this equipment.
•Use insulated wrenches, screwdrivers, cutters, pliers and other tools.
WARNING: Rectifier output DC circuits will be damaged if the batteries are installed incorrectly. Ensure proper battery polarity and that the battery is isolated from the rest of the system.
Planning the Battery installation
The battery cable(s) should be sized to limit the voltage drop from the dc power plant to the battery during charging per system design requirements. The cable(s) must also carry the full load current during battery operation. If assistance is required to determine the necessary cables for the application, contact your sales representative or APC (Refer to Section Error! Reference source not found. for APC Customer Support information). A fuse or circuit breaker (various options are available from APC) is recommended in the negative line to protect the cables from the battery to the DC power plant. If a circuit breaker is used, the power plant can monitor auxiliary contacts from this breaker.
Connecting the Cables
WARNING: Make certain that the battery polarity is correct when making connections to the DC power plant. Incorrect connections can cause severe equipment damage.
The battery cable connections are located at the rear of the unit as shown in Figure
