4.6 Charging the high voltage lithium batteries
Chargethebatteryasfollows:
1.SwitchignitionkeytoOffposition.Emergencystopswitchmustnotbepulledoff
(must be engaged).
2. Connect charging plug to the intended power-outlet in the harbour.
3.On-boardcomputerperformsself-testoneachcomponent.Inthecourseofthis,high
voltage batteries are connected and display switches to Charger screen.
4. Start charging operation by switching On/Off switch on the Charger screen to On.

In case the power-outlet available for charging cannot deliver the required power, char-
ging power may be reduced in the Settings – Chargers menu until trouble-free charging
is possible (refer to 5.4. On-board computer and touchscreen display). Charging will then
take more time.
