Safety information
Manual neoTower®Power Storage | (02/2022)
2.4 Safety information
⚠ DANGER!
Life-threatening electric shock
Bridging the battery terminals causes a short circuit
which causes current to flow. Such a short circuit must
be avoided at all costs. Observe the following points:
►Use insulated tools and gloves.
►Never place any tools or metal parts on the battery
modules.
►Put down metallic objects before starting work.
►Never operate the system in potentially explosive
atmospheres or areas with possible fire hazards.
⚠ DANGER!
Fire hazard due to improper handling
Improper handling can cause lithium battery cells to
ignite. For this reason
always observe the following specifications for handling
lithium battery cells:
►Do not install or operate the battery modules in
potentially explosive atmospheres or in areas with
high humidity.
►Store the battery modules in a dry place and within
the temperature ranges specified on the data sheet
►Do not open, puncture or drop the battery modules.
►Do not expose the battery modules to high
temperatures.
►Do not throw the battery modules into a fire.
►Do not use defective or damaged battery modules.
⚠ DANGER!
Risk of death due to misuse
Any use of the battery storage system other than for its
intended purpose or any other use
can be extremely dangerous.
⚠ WARNING!
Moisture!
►The system must be installed in a dry place.
►The system and external cables must be protected
against exposure to water.
►Never clean the system with liquid cleaning agents.
2.5 Protective devices
⚠ WARNING!
The protective devices serve to ensure safety when
handling the system. Missing or defective protective
devices can result in hazardous situations.
►Make sure that protective devices are not removed.
►Observe the safety instructions on the individual
components of the system.
►
2.6 Handling the battery modules
⚠ WARNING!
The battery modules that are compatible with the
power storage system are protected by several safety
devices and are safe when used as intended. If the
batteries are not used as intended or in the event of a
fault, the battery cells inside the
battery modules can be damaged.
This can have the following consequences:
• Considerable heat generation on the surface of the
battery cells.
• Leakage of electrolytes, fumes and/or smoke.
• Ignition of the discharged electrolytes and a flash fire.
• Irritation of the skin, eyes and mucous membranes
caused by fumes or smoke from burning battery
modules.
To ensure compliance with the intended use of the unit:
►Do not open the battery modules.
►Do not mechanically damage (pierce, deform,
dismantle etc.) or otherwise modify the battery
modules
►Do not heat the battery modules, keep them away
from igniting sources and only operate them within
the permitted temperature range.
►Do not allow the battery modules to come into
contact with water (except to extinguish the power
storage system in the event of a fire).
►Do not short-circuit battery modules.
►Do not continue to use battery modules that have
been damaged in any way.
►Do not permit exhaustive discharge of the battery
modules or charge them with external chargers.
►Do not operate the battery modules outside the
storage system.

3. Product information
3.1 Principle of operation
The use of a specially designed power storage
increases coverage of the building’s power
consumption. The excess electricity produced is stored
in high-quality batteries.
In addition, a blackout start system can secure the
power supply in the event of a blackout of the mains
supply network. In the event of a power failure, the
system supplies the connected consumers. The
system is switched over within milliseconds, ensuring
uninterrupted operation of the electronic devices. The
systems are of modular design and can be calculated
for the required storage capacity.
3.2 Registration with the energy supplier
The energy supplier must be notified when the system
is installed. Operator requirements:
►Inform yourself of any relevant requirements.
►Notify the energy supplier before installing the
system.
►Meet the energy supplier specifications (e.g.
registration, approval).
►Submit all the relevant system data to the energy
supplier.
Technical data
The technical data sheets can be downloaded from
the manufacturer's website.
