- Keep all potentiometers at minimum position.
- Keep AC, DC and Charger ON/OFF switches at "OFF" position.
- Keep Auto change over switch on manual position.
- Check all the input/output voltage and indication lamps.
- If any adjustment in the output voltage/current is required, potentiometer is provided on front door of the panel to adjust set voltage/current at the required value.
- Do not temper the setting of any other potentiometer, which may otherwise lead to serious malfunctioning of the charger.
- Do not connect Battery bank before checking Battery chareger's basic functionality.
