ABB AC500 Safety Instructions page 5

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 short-circuits 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 sur faces.
Escaping lithium is a health hazard.
Never charge lithium batteries!
Lithium batteries are primary cells and cannot be re-charged. 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
Avoidance of electrostatic charging
Electrostatic charging can cause internal defects of the devices and impair their proper function.
CAUTION Observe the following rules when handling the system:
– Touch an earthed object in order to discharge 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 suitab-
