WARNING
Risk of electrical shock, fire, personal injury or death.
- Do not short-circuit the battery poles or power wires and always check correct battery polarity.
- Do not modify or repair the unit.

Batteries must be completely discharged before replacement and can be returned to the supplier of the battery

TORAGE
Do not store batteries or battery modules at temperatures higher than 25°C or performance and lifetime may change.
Do not store discharged batteries. Keep batteries fully charged!
Charge retention is important to get the longest battery life. Stored batteries which are not fully charged age faster
then charged batteries.
Do not store batteries longer than 9 months without charging or performance and lifetime may change. Every 9
months or whenever the open circuit voltage (OCV) falls below 12.6V, the battery module should be charged. Apply a
charging voltage of 13.8V (at 25°C) for 72 hours. Batteries with an OCV below 12V must not be charged anymore and
must be disposed.
8. I
NSTALLATION
I
NSTRUCTIONS
Install batteries in an enclosure providing protection against electrical, mechanical and fire hazards.
Do not install the battery upside down.
Do not cover or block the pressure release valves on top of the battery.
Hydrogen gas can be released via pressure relief valves. It will form an explosive mixture in air when the concentration
exceeds 4% in volume. It is mandatory to ensure sufficient ventilation of the battery. The necessary air flow must be
calculated according to EN 50272-2.
CAUTION: The unit contains wet cell batteries. Ventilation of the installation room in accordance with the rules of
Canadian Electrical Code, part 1 is required if used in Canada.
The maximum surrounding air temperature is +50°C / +122°F. The operational temperature is the same as the ambient
or surrounding air temperature and is defined as the air temperature 2cm below the device.
