Information 

Observe the following specifications for all the work described:

• Country-specific, national, legal and official regulations,
• Local restrictions and export restrictions,
• Manufacturer specifications from component and vehicle manufacturers,
• Component-specific specifications.

These strict specifications apply in particular to:

• Storage, installation and removal, transport and disposal of vehicles, assemblies, operating materials and auxiliary materials,
• Handling defective and potentially hazardous vehicles as well as assemblies,
• Handling battery electric vehicles and high-voltage components.

Consider relevant and qualified sources of information such as local authorities, competent importer, associations and specialised websites for this purpose. Only deliver items to be disposed of to authorised reception points.

These regulations to be complied with have to be checked, observed and, if necessary, documented by the person responsible for the vehicle for all life phases and work.

Information 

Adapt for each new cell module! New cell modules have a state of charge of 30%.

Information 

During the test sequences, green tick marks indicate whether lines were connected correctly. However, these only light up as soon as both ends of the lines have been connected.

Information 

The difference in voltage between the module and the existing modules can be max. 0.3 V.

Information 

The PIWIS Tester  instructions take precedence since the description may be different with later Tester releases.

The procedure described here has been structured in general terms. Different text or additional information may appear on the PIWIS Tester.
