Electric system and handling of the battery pack
The loader is fitted with a high-energy battery pack that can output hazardous, lethal
levels of current and voltage. Misuse or using of damaged battery system creates a
risk of battery explosion, fire, hazardous electric shock, and acid spill from battery.
Follow the instructions regarding charge, use, and maintenance of the battery and the
electric systems in this manual.
Battery systems on e5
The energy from the battery pack is used in two
parallel systems:
48-volt supply from battery is converted by an
inverter to a high-voltage and high-current
electric power to drive the electric motors
A 48 v to 12 v converter supplies electricity to the
control systems of the loader, hydraulic valves,
dashboard, electric socket etc.
Never modify the 48-volt system or connect any
device directly to it. This system can output high
current that can kill or cause electric shock and
burns, if handled carelessly and safety systems are
bypassed. See maintenance instructions on page
75.
Short-circuit can cause the
battery to explode or burn -
Disconnect battery before
maintenance.
Isolate the battery from the electric
systems of the loader by
separating its quick connector
before working on the electric
systems of the loader, see page
82. Check that all insulator sleeves
and caps are in good condition and
that battery terminals are not
exposed. Never lay metal objects
on the battery.
Handle battery with care
Battery contains corrosive sulphuric acid which
causes serious burns upon skin contact. Avoid
contact with skin or clothes. If electrolyte gets on
your skin or clothes, flush with a lot of water. In
case of contact with eyes, flush with a lot of
water for at least 15 minutes and see a doctor
immediately.
If a fuse is blown repeatedly, find out the cause.
Always use fuses with correct rating.
Disconnect the battery by separating the main
connector. Never disconnect individual battery
cells.
Risk of exposure to battery acid
- Handle battery with care and
read maintenance instructions.
Using a damaged battery, extreme
heat, improper charging procedure,
or other type of wrong use can
cause the battery cells to rupture
and leak or spray acid electrolyte.
Always follow use and
maintenance instructions. Never
use damaged battery.
Lead warning - Wear protective
gloves. Battery and its terminals
contain lead, a harmful substance
which should not be handled more
than what is necessary. Wear
protective gloves when handling
battery. Wash hands with soap and
water after handling the battery.
