Error detection
Cause
Battery voltage is smaller than
10 V (840-012PP)
or 20 V (840-024PP)
Thermal overload
Fuse is defective (in the inverter
or in the vehicle)
Battery voltage is under
10.7 V (840-012PP)
or 21.4 V (840-024PP)
Poor contact at the battery with
load
Permanent load is too high
Switch-on current is too high
Technical data
10V~15V+/-0.3V
105 x 57 x 225 mm
Troubleshooting
Load battery (start motor)
Switch off power consuming unit
let inverter cool down and
provide for better ventilation
Fuse to be replaced by a
qualified electrician
Charge battery
Cleaning the contacts
Reduce load
