42V to 58V according to battery bank status of charge (SOC).
VBAT = Battery bank voltage.
C - BATTERY CONNECTOR
Place to connect the battery or bank of batteries.
D - BATTERY PROTECTION FUSE
Attention
The battery fuse varies depending on the model of the DC UPS check the fuse chart. If necessary
replace, use one of the same model and value.
E - GRID INDICATOR LED
Indicates whether the DC UPS is being powered by the AC input.
F - CHARGING BATTERY INDICATOR LED
Indicates that the DC UPS is charging the battery bank.
G - DISCHARGING BATTERY INDICATOR LED
Indicates that the DC UPS is discharging the battery bank.
H - OVER TEMPERATURE INDICATOR LED
LED on, indicates that the DC UPS temperature is above acceptable. Blinking LED, indicates fan failure.
I - OVERLOAD INDICATOR LED
Led on, there is overload on DC UPS. Indicates that the DC UPS is delivering power above capacity, see
power capacity according to model and charger configuration. In this situation, the DC UPS will charge the
batteries only with 1A.
J - STARTING KEY
Used when the DC UPS is without AC power, it is possible to install the bank of batteries to start feeding
equipment.
K - CHARGE CURRENT CONFIGURATION KEY
Charging current configuration: 1A, 3A or 5A. Battery Type Setting: Stationary or VRLA.
The 10A charge current is only available for some models.
