Safety instructions
WARNING
Damage to the TEBS E Modulator caused by not using original WABCO ca-
bles
Using cables not approved by WABCO can result in functional impairments and
fault entries.
Cables with open ends must be laid in manner that ensures no water can enter the
modulator via the cables to damage it.
– Only use original WABCO cables.
WARNING
Dangerous voltages during electrostatic painting and welding
Dangerous voltages can damage the electronic control unit.
– If electrostatic painting or welding work is carried out on the vehicle, the follow-
ing measures must be implemented:
Moving or insulated components (such as axles) must be conductively con-
nected to the vehicle frame (chassis) using suitable earth terminals to ensure
that no potential differences are allowed to build up and cause a discharge.
or
The ABS connection lines on the modulator must be disconnected and the
electrical terminals covered (with sealing plugs for example).
– Ground connections for welding and paint spray systems must always be con-
nected on the parts that are being worked on.
CAUTION
Damage to the modulator due to painting over
Connector locks and plastic pipes of the pneumatic couplings can no longer be
released after painting.
– Do not paint over the modulator.
