1.1.3. CHECKING, TRANSPORT AND STORAGE
Please check the transportation and component package for any damages and compare the content
with the bill of delivery. In case of damages inform ACTIA I+ME GmbH immediately.
The Components may only be stored in rooms where they are safe from dust, humidity, splash water
and dropping water and where the denoted storing temperatures are guaranteed.
1.1.4. REMARKS
Before placing into operation please carefully read the following
security instructions.
The correct on site installation methods and the proper handling
procedures for the Lithium Ion Cells, and the following usage and
service procedures cannot be controlled by ACTIA I+ME. Therefore
ACTIA I+ME will not accept any responsibility for damage or costs
resulting from the incorrect installation or operation in any form.
- Use insulated tools, wherever possible. Voltages may exceed some hundreds volts DC.
- Always use qualified proper and, wherever applicable, polarity proof connectors.
- Especially the wiring of the cells has to be done with extreme precaution. See chapter
3.4.4.2. Inspect the connections regularly.
- Use only appropriate cables; especially for ampacity of power cables refer to DIN VDE
0276-1000 or corresponding national directives.
- Cable dismantling, attaching end sleeves etc. must not be done near the electronic boards
to avoid short circuits due to single wire strands.
- Special care has to be taken when measuring or testing with
equipment electrically referenced to mains protective earth (PE; e.g.
mains supplied scopes); especially when master and slave units are
connected and the master does not have an isolated power supply of
its own. Remember that a master unit connected to a PC via RS232
interface is connected to PE anyway. The master unit’s reference GND-
level is the supply minus-pole (KL31), the slave unit’s reference GND-
level is cell contact 7!! There will be a voltage difference of 21 V with
ten cells at least, depending on the amount of single cells connected; with an 80-cell
system e.g. the voltage difference between KL15 and Slave GND can be up to 300 VDC and
more.
- A short between both reference levels will destroy the battery, the electronics and the test
equipment and may lead to fire or even explosion.
- BMS MASTER and Slave boards are ESD (electrostatic discharge) sensitive devices.
Therefore, proper ESD precautions are recommended to avoid performance degradation or
loss of functionality.
