Proper use
Important note
W.EASY Trailer Power Rev.2.0 must only be used on 24V and 12V vehicles and their trailer
systems in accordance with proper use!
Note
The vehicles and the trailer systems must meet the country-specific specifications of the
relevant traffic regulations.
The equipment must be used for the following functions:
Power supply of the trailer electronics, 24V and 12V systems, via the following connections:
o7-pin ISO 7638 connection (24V system)
o13-pin ISO 11446 connection (12V system)
Test of trailer lighting as required via the following connections:
o15-pin ISO 12098 connection (24V system)
o13-pin ISO 11446 connection (12V system)
Test of the control signals for the trailer lighting coming from the tractor via the 15-pin ISO 12098
connection (24V system)
Control of PINs 10, 11 and 12 of the ISO 12098 connection as required with the following signals:
o24V voltage level
o0V voltage level/earth
Measurement of the voltages and/or currents at the individual PINs of the corresponding
connections:
oISO 7638 PIN 1 and 2
oISO 12098 PIN 1, 2, 3, 5, 6, 7, 8, 10, 11 and 12
oISO 11446 PIN 1, 2, 4, 5, 6, 7, 8 and 9
ISO 12098: Only use the connection on vehicles with 24V on-board voltage!
ISO 11446: Only use the connection on vehicles with 12V on-board voltage!
Use for any other purpose is considered improper use.
The user is liable for any damage ensuing from improper use.
