ATTENTION
Risk of damage from AGM and gel batteries!
Opening or drilling the battery housing will damage an AGM or
gel battery. It must then be replaced.
Do not open the battery housing and do not drill any holes.
Do not cover the pressure relief valve and do not change it.

ATTENTION
Risk of damage to the control electronics!
The control electronics can be destroyed by reversing the polarity
of the battery connections.
Take care to ensure the correct polarity when connecting the bat-
teries.
WARNING
Danger to life from fire or explosion if batteries are deeply
discharged!
Incorrect charging of deeply discharged batteries can cause a
fire.
Do not start the device if the battery is deeply discharged.

a for BD 70/75: Install the 2 battery holders and for 115 Ah:
Tighten at the left and middle threaded holes.For BR 75/75
and BD 70/75: 170 Ah / 180 Ah: Tighten at the right and
middle threaded holes.
b For BD 80/100 and BR 85/100: Insert one or two spacers
flat lengthwise or vertically between the front batteries and
the fresh water tank so that the batteries cannot slip forward.
