The lead accumulators are connected to the accumulator cables of the external power supply. The lead accu-
mulators are connected to the terminals “+Bat” and ”-Bat”. If two 12 V lead accumulators are present, they
must be connected in series (plus pole of one accumulator to minus pole of the other).
If external buffer accumulators are used, accumulator safeguarding must be performed by the user! For safety
reasons, the safeguarding element (overload and short circuit protection) must be arranged in close proximity
to the accumulator set itself! If lead accumulators are used, sufficient air flow must be provided according to
VDE 0510, part 2.
NOTE
Only use VdS approved lead accumulators. Never use different lead accumulator types, nor lead
accumulators of different manufacturers, nor old and new accumulators together.
CAUTION
Protect, i. e. insulate the poles when connecting lead accumulators. In case of short-circuits
there is the danger of severe burns by arcs or hot parts.
CAUTION
Hydrogen is generated during the charge of lead accumulators, forming dangerous oxyhydro-
gen. Ensure proper ventilation.
CAUTION
The lead accumulator voltage must correspond to the rated voltage of the charge rectifier! Never
confuse the polarity of lead accumulators and never short-circuit lead accumulators!
In case of non-observance there is the danger of severe burns by arcs or hot parts.
NOTE
The lead accumulators must be fixed properly.
Never install unsecured lead accumulators into the unit; danger of
short-circuits
!
NOTE
If the
AKKU
TEC
is connected in parallal (Master/Slave-operation) the 24 V accumulator lines
must be connected to each other. It is not at all permissible to connect an accumulator line at the
master and the other accumulator Iine only at the slave.
A connection from the plus to the corresponding negative pole is absolutely necessary.
NOTE
Used lead accumulators must be disposed
