Power Supply: 110/220, 50/60Hz external charger with 18V
12V vehicle power
DC
In this case the low-potential of the vehicle's 12V outlet is at the potential of
terminals E (X) and ES (Xv) of the ground tester. For safety reasons, do not
connect or use the unit if there is a possibility that voltages at E (X) or ES (Xv)
could exceed 32V.
Fuse: 0.63A, 250V, 5x20mm, 1.5kA

Fast charging is active (normal state)
Battery voltage is too low for a fast charge - charging at a lower current
Battery voltage is too high for a fast charge - charging at a lower current
Battery is too warm for a fast charge (>40°C) - charging at a lower current
Battery is too cold for a fast charge (<0°C) - charging at a lower current
Battery is full - switch to trickle charging
