Safety instructions
Voltage must be supplied to BAT 6120 via a grounded
mains voltage system.
The power supply cable and battery cable B+/B– must
be in perfect condition.
Only use the battery cable B+/B– supplied by Bosch.
Do not extend or shorten the battery cable B+/B–.
When using an extension cable, make sure that the to‐
tal current of all devices connected to this extension
cable does not exceed the permissible current for the
extension cable and the upstream fuse in the fuse
box.
Only charge batteries in well ventilated areas.
Avoid naked flames and spark formation when charg‐
ing batteries.
Do not attempt to charge non-rechargeable batteries.
Do not charge lithium iron phosphate batteries (LFP =
LiFePO4) without the battery management system
(BMS).
Switch off all electrical equipment in the vehicle
whilst charging (also applies to charging of exhausted
batteries).
Do not short-circuit battery terminals.

Battery hazard
Risk of chemical burns – Electrolyte leaking from bat‐
teries and accumulators may cause eye and skin burns.
Make sure that any leaking liquid (electrolyte) does
not come into contact with skin or eyes.
If electrolyte contacts the relevant areas, immediately
rinse with water and then consult a medical professio‐
nal.
Do not short-circuit batteries and accumulators.
---
Risk of fire, explosion – Batteries and accumulators
can cause burns and injury if overcharged (gassed) or
short-circuited.
No open flames or sources of sparks.
Do not smoke.
Ensure that there is sufficient ventilation and extrac‐
tion in enclosed rooms.
Do not short-circuit batteries and accumulators.
