0.2 Safety instructions for working with lead-acid batteries
When working on batteries, always observe the safety regulations documented in DIN EN
50110-1 (VDE 0105-1) Operation of electrical installations:
• Always proceed in the correct order when installing and removing the battery and when connec-
ting it to the charger.
• Pay attention to the polarity!
• Make sure the connections are tight.
• Use only battery charger leads that are in perfect technical condition and that have adequate
cross-sections.
• Batteries must not be connected or disconnected while current is flowing or while the charger
is switched on.
• Before opening the load circuit, make sure that the charger is in a switched-off state by measu-
ring the voltage.
• Secure the charger to prevent it from being switched back on again!
• Heed the instructions given in the operating manual provided by the manufacturer of the battery
charger.
Danger!
Under certain conditions, there is a risk caused by electrical battery voltage and in the event
of a short circuit, extremely high short circuit currents may flow.
There is a risk of explosion and fire due to explosive gas.
Observe the following regulations (IEEE standards valid for USA only):
– ZVEI publication „Instructions for the safe handling of electrolyte for lead-acid accumulators.“
– VDE 0510 Part 2: 2001-12, in accordance with IEC 62485-2: „Safety requirements for secon-
dary batteries and battery installations - Part 2: Stationary batteries“.
– DIN EN 50110–1 (VDE 0105–1): Operation of electrical installations; German version EN
50110-1:2004.
– IEEE Standard 485–1997: „Recommended Practice for Sizing Large Lead Acid Storage Batteries
for Generating Stations.“
– IEEE Standard 1187–2002: „Recommended Practice for Installation Design and Installation of
Valve Regulated Lead-Acid Storage Batteries for Stationary Applications“.
– IEEE Standard 1188–2005: „Recommended Practice for Maintenance, Testing and Replacement
of Valve Regulated Lead-Acid (VRLA) Batteries for Stationary Applications“.
– IEEE Standard 1189–2007: „Guide for Selection of Valve-Regulated Lead-Acid (VRLA) Batteries
for Stationary Applications“.

Batteries contain corrosive acids which can lead to chemical burn on skin and eyes if the
battery is damaged.
You must wear safety goggles while handling the battery!
Wear all the intended personal safety clothing while handling the batteries.
1. When renewing old batteries, ensure that all electrical loads are switched off before removing
the old battery (separators, fuses, switches). This must be carried out by qualified personnel.
Danger!
2. Remove all wrist watches, rings, chains, jewelry and other metal objects before working with
batteries.
3. Use insulated tools only.
4. Wear insulating gloves and protective shoes (refer to also to
Chap. 2.2
).
Danger!
5. Never place tools or metal components on top of the batteries.
Danger!
6. Make sure that the battery or batteries are not mistakenly grounded. If the system is grounded,
terminate the connection.
Touching a grounded battery by mistake can result in severe electric shock. The risk caused
by an incorrect connection can be significantly reduced by terminating the ground connection.
Attention!
7. Before establishing connections, make sure to check the correct polarity - better one too many
times than one too few.
Danger!
8. Filled lead-acid batteries contain highly explosive gas (hydrogen/air mixture). Never smoke,
handle open flames or create sparks near the batteries. Always avoid electrostatic discharge;
wear cotton clothing and ground yourself if necessary.
Danger!
9. Blocks/cells are very heavy. Make sure they are installed securely. Only use suitable means of
transport. Do not lift or pull up blocks/cells on the poles.
Danger!
10. Never carry batteries by the battery terminals.
Attention!
11. These batteries contain lead and cannot under any circumstances be disposed of with
household waste or at a waste dump at the end of their service life (for more information,
refer to Chap. 1.4
).
Attention!
12. Contains lead-metall (CAS- Nr. 7439-92-1). This metall is one of the reach list chemicals.
