Batteries)
Pins 1 to 4 are for battery measurement (only applicable to
MGE Galaxy 3500 XR Battery Enclosures (see J200 drawing).
Pins 5 and 6 are for external maintenance bypass Q3
(auxiliary switch N/C type).
When Q3 is closed, signals are fed back to the UPS controller
(see Q3 drawing).
Pins 7 and 8 are for external charge control. When 7 and 8 are
closed, the UPS charges batteries with a pre-defined
percentage (0-25-50-75-100%) of the maximum charging
power. To be used in generator applications, or if special
codes require control of charging.
When Q3 is closed, signals are fed back to the UPS
controller.
