This allows the use of an auxiliary energy source other than the primary mains power supply in the event of
outage.
10.6 EXTERNAL BACK-FEED PROTECTION.
The UPS systems are designed for the installation of an external device that protects against the back-feed of
dangerous voltages on the power line, or if it is a separate line, on the auxiliary back up power supply line. The
BKF card shown in figure 10.6.1 is used to control the external device. The BKF PCB is installed in the position
