UPS Operating Modes (Continued)
Batt T Comp
This allows you to adjust the battery charger voltage compensation to match the battery manufacturer’s
specifications. The factory default value is –5 mV/°C/Cell. You can adjust it to –2.5, –4 or –5 mV/°C/Cell.
NOTE: The display rounds up the –2.5 value to –3.
Hot Swap
This allows you to change the battery string without turning off power to the loads.
Bypass
CAUTION: If the UPS is not switched into bypass before switching the MBP
to Bypass, or the MPM to Line/Transfer, the UPS’s internal fuses could blow.
This feature locks the unit into line mode regardless of any changes in line conditions. This allows you to
change the batteries or set a bypass switch to bypass in order to replace or service the unit.
