10.3 How to Charge the External Battery
NOTICE
◇ The battery is charged while the power is "ON," regardless of the operation state
of the STP pump.
The STP control unit is equipped with a constant voltage (55 V) circuit and a constant
current (0.3 A) circuit for charging the battery.
After a power failure, charge the battery for approx. 12 times the BATTERY BACKUP time.
For example, if the BATTERY BACKUP time is 6 minutes, it takes approx. 75 minutes to
charge the battery.
If a power failure occurs 2 times within 90 minutes, charge the battery for more than 90
minutes before starting the STP pump.
