In addition to safety requirements, special care should be 
taken when handling Li-ion Battery Units.  

 

Battery Units should always be handled with care, as 
they contain a lot of power and energy. 

 

Do not touch the terminals, as it can cause electrical 
shock which can lead to muscle paralyzing effects 
such as sudden cardiac arrest, respiratory paralysis, or 
ventricular fibrillation.  

 

Do not tamper with the Battery Unit, or try to open it.  

 

Avoid dropping Battery Units to the ground, or in 
other ways mechanically damage them, as this is a 
potential safety risk.  

 

Keep away from water or other liquids.  

 

Keep the Battery Units away from direct sunlight for 
extended periods of time, and keep away from heat 
sources, fires etc. at all times. In order to guaranty 
safety the Battery Unit shall not be exposed to 
temperatures above 60 °C. 

 

If a battery shows signs of damage or has been 
dropped, do not use it.  

 

If the battery is leaking liquids, do not touch them as 
they are toxic and cause skin irritation or burns, and 
dispose of the leaking battery.  

 

If leaking liquids come in contact with the skin, wash 
with soap and cold water for at least 15 minutes and 
remove contaminated garments. Seek medical 
attention if necessary.  

 

If leaking liquids come in contact with the eyes, do not 
rub eyes. Immediately flush eyes thoroughly with cold 
water for at least 15 minutes, then seek immediate 
medical attention. 

 

If leaking gases are inhaled, move to fresh air, monitor 
breathing and blood circulation, take appropriate first 
aid actions if necessary, then immediately seek 
medical attention.  

 

In case of fire/explosion/smoke, water in large 
quantities can be used as an effective fire suppression 
agent. Once the fire has been extinguished, the 
Battery Unit needs to be monitored for an extended 
period of time (24 hours) due to the risk of the fire 
reigniting.

Receiving the Shipment 

 
To avoid injuries to the personnel unpacking and installing 
the battery, it is important to remember that the battery is 
heavy and could require two persons to lift and install. To 
avoid damages to the battery during unpacking and lifting, 
it is important to handle the battery with care when lifting 
and installing the battery. Protect the surfaces of the 
battery to avoid scratches from sharp tools and other 
objects. 

 
Note: Handle the battery with care. The edges and corners 
must not be knocked against hard surfaces. Do not use 
sharp tools when removing the packaging. 
 
Follow these instructions when unpacking the battery: 

1.

 

Examine the packaging for damage. If it has been 
damaged, immediately register a complaint with the 
transportation company. 

2.

 

Check that the items delivered correspond to the 
packing list. 
 

Item no.  Name

Mounting brackets 

M4 screws

Cage nuts 

M6 screws 

 

3.

 

Unpack the battery. 

 
Leave the final unpacking of each unit until it is required 
during the installation. This will help to avoid losing or 
misplacing smaller items such as sets of parts supplied with 
the units.  
 
Recycle all waste materials that can be recycled and sort 
waste so that it can be disposed of according to local 
regulations.

Warning! 

 

Improper handling of batteries can cause 
them to short-circuit, which can result in 
serious injury due to high energy levels. 
Exercise the necessary care when working 
with batteries. Remove any items that can 
cause short circuits, such as, rings and 
bracelets. 

 

 
 
 

 

Warning! 

 

High energy levels are present in this unit. 
Improper handling of the unit can lead to 
short circuits that can result in serious injury. 
Exercise care when working with this unit.
