 Do not obstruct the ventilation for cooling! 
The ventilation slots on the upper and lower side of the devices must not be covered by wiring, cable 
ducts and things like that. 
 Run signal and power wiring separately! 
Signal and supply lines (power cables) must be laid out so that no malfunctions due to capacitive and 
inductive interference can occur (EMC). 
 Precautions against wiring short-circuits and breakages 
Connection plans and user software must be created so that all technical safety aspects, legal 
regulations and standards are observed. In practice, possible shortcircuits and breakages must not be 
able to lead to dangerous situations. The extent of resulting errors must be kept to a minimum. 
 Use only ABB approved lithium battery modules! 
At the end of the battery’s lifetime, always replace it only with a genuine battery module. 
 Never short-circuit or operate lithium batteries with the polarities reversed! 
They are likely to overheat and explode. Avoid chance short circuiting and therefore do not store 
batteries in metal containers and do not place them on metallic surfaces. Escaping lithium is a health 
hazard. 
 Never charge lithium batteries! 
Lithium batteries are primary cells and cannot be recharged. Attempts to charge lithium batteries lead to 
overheating and possible explosions. 
 Dispose of lithium batteries environmentally consciously! 
Do not open lithium batteries and never throw them into fires (risk of explosion). Do not dispose of along 
with the household rubbish but in an environmentally conscious manner, in accordance to local-authority 
regulations. 
Additional notes 
 ATTENTION 
Avoidance of electrostatic charging 
 
Electrostatic charging can cause internal defects of the devices and impair the 
proper function. Observe the following rules when handling the system: 
•  Touch an earthed object in order to discharge the electrostatic 
charging. 
•  Wear a suitable earthed strap around your wrist. 
•  Do not touch any connections or pins on the printed circuit boards. 
•  Do not touch any circuits inside the devices. 
•  If available, use a work place which is equipped with suitable 
electrostatic discharge. 
•  In order to avoid electrostatic charging, the devices must only be 
stored when packed in suitable packaging material.
