DC Cabling Between Cabinets
Refer to “Battery Cabinet Installation” in the UPS user's guide for the
procedure to connect the cable assembly between the external battery
cabinet and the UPS cabinet, or to additional external battery cabinets.
NOTE
See Figure 2 on page 3 for the proper location of cabinet-to-cabinet wiring, which
must be in the second cabinet section.
Setting DIP Switches
The DIP switches on the rear panel of the Battery Charger Module are
functional only when the module is installed in an external battery
cabinet. The DIP switches control two functions: the output current
limit and a periodic float charging to equalize all battery capacities.
NOTE
Set the DIP switches ONLY if the Battery Charger Module is placed in the ASY-0739
12-slot external battery cabinet. When the module is placed in the UPS cabinet, do not set
the DIP switches.
Output Current Limit
The Battery Charger Module is capable of producing up to 5A, 10A, 15A,
or 20A when installed in an external battery cabinet. Discharged
batteries must be recharged at an optimum rate, neither too quickly nor
too slowly. For optimum charging of batteries, you must set DIP
switches 1 and 2.
Follow the guidelines in Table 3 to determine the proper output current
setting and set DIP switches 1 and 2 accordingly (see Figure 4).
