oIf the electrolyte is ingested, promptly induce vomiting.
oSeek immediate medical attention.
The previous instructions are provided to address potential risks associated with electrolyte
leakage. It is important to prioritize your safety and seek professional medical assistance without
delay in case of exposure to the leaked substance.
1.4.2 Fire
In the event of a fire, it is important to have an ABC or carbon dioxide extinguisher readily available.
Do not use water to extinguish the fire.
WARNING
The battery pack may catch fire when heated above 150°
If a fire breaks out where the battery is installed, please follow these actions:
•Prioritize extinguishing the fire before the battery catches fire if it is safe to do so. Use
appropriate fire extinguishing methods and equipment according to the type of fire (e.g.,ABC
or carbon dioxide extinguisher). Ensure your safety and consider seeking professional
assistance if necessary.
•If the battery has already caught fire or if it is not safe to attempt extinguishing the fire,
prioritize the immediate evacuation of all individuals from the area. Follow established
emergency evacuation procedures and ensure everyone moves to a safe location. Contact
the appropriate emergency services to report the fire.
Note: The above actions are intended to address fire situations where the battery is involved. Always
prioritize personal safety and adhere to established emergency procedures.

13
4.5 Storage
If the battery is not going to be installed immediately and needs to be stored for a long
period, please choose an appropriate location for storage. Follow these instructions for
storage:
⚫Do not stack more than four battery boxes.
⚫The recommended storage temperature for the battery is in the range of -20°C to 30°C.
⚫Avoid exposing the battery to water.
⚫If the battery needs to be stored for over 3 months, it will discharge at a minimum rate
and the capacity may degrade depending on the storage time.
⚫If the battery is stored for over 6 months, it is recommended to connect the battery
with the inverter and commission the system.
⚫The battery boxes should be stored upright as shown in the following figure and should
not be stacked upside down.

5.2 Before Installation
There are a few things to check before installing the battery to ensure that it is free of
defects.
Check the battery voltage using the following instructions:
⚫Press and hold the power button for 4 seconds and release it when two indicators
turn on.
⚫Measure the voltage at the terminal interface using a voltmeter. If the voltage is
lower than 48V, do not use the battery and contact customer service.
⚫Turn off the battery after checking voltage.

15
5.3 Battery Mounting
The ESP-5100 is designed as a rack mount type battery, this adds flexibility on installation
and modularity for different configurations. We offer different rack and enclosure solutions
for our batteries, see instructions below depending of the type of mounting.
5.3.1 Rack Mounting (R6 / R12)
1. Place the Rack in the location desired (refer to the details about the installation
location described in Chapter 4.2). The enclosure should be moved close to its
installation location inside its shipping container before it is unpacked. The
enclosure must be installed in a structurally sound area with a level floor that is
able to bear the weight of the rack + the intended number of batteries to be installed
inside.
CAUTION
Our rack solutions are designed for indoor installations IP20/NEMA1.
If the batteries are intended to be used outdoors, a cabinet / enclosure is required.
Our Racks are designed for high voltage / series applications, if you intend to
use the rack for the ESP-5100 battery please ask a sales representative for
special cables and busbars available.

16
2. Adjust leveler feet (if included), lower each leveler unit it reaches the floor, make
sure each leveler contacts the floor solidly. After lowering each leveler, use the
carpenter's level / bubble level to confirm that the rack is level. Adjust levelers as
needed to get level.
3. To secure the rack to the building structure for stability, attach the provided
brackets to the wall or to the floor (depending on the rack model) using adequate
screws. Verify foundation for seismic installations.
