2.3. Electrical shocks
and burns
Batteries assembled from a large
number of monoblocks can attain
high voltages. Therefore great
care caution must be taken during
the installation and maintenance
of a battery system to avoid
serious burns or electrical shocks.
&
Cut off the AC and DC circuits
before working on batteries.
Make sure that people understand
the risk of high voltage batteries
and that all manipulation is
carried out with insulated tools
and other adequate protection
equipment.
2.4. Possible dangers
through hydrogen
Low maintenance STM
monoblocks are connected in
hydraulic series. The hydraulic
circuit exhausts oxygen and
hydrogen gases that are
produced during overcharge.
&
The hydraulic system can
contain highly explosive gases
at any moment.
All interventions on the battery
require particular attention to
prevent of any kind of leakage.
If a leak is detected, it must be
repaired immediately.
Furthermore, general safety rules
must be strictly observed:
dispersion of gases as they leave
the hydraulic system to avoid the
forming of dangerously
concentrated hydrogen gas
pockets; and good ventilation.
Keep the battery away from any
heat or ignition source.
