UPS BATTERY MODULE HARDWIRE CONNECTION
In addition to the instructions listed below, follow all warnings found in the Safety section prior to connection.
WARNING!
Before attempting to connect the UPS Power Module to the UPS Battery Module, qualified personnel must remove all fuses from all
UPS Battery Modules.
CAUTION!
Make certain that your UPS Power Module and UPS Battery Module use the same DC voltage before connecting them. When
connecting multiple Battery Modules to a single Power Module, the Battery Modules should be approximately the same age. Do not
connect or disconnect Battery Modules while the Power Module is operating on battery power, due to the possibility of dangerous arcing.
The UPS Power Module will not start without a connection to a charged UPS Battery Module. If you plan to store your Battery
Module(s) for an extended period of time, fully recharge its batteries every three months by connecting it for at least 12 hours to a UPS
Power Module that is connected to AC input.
