DANGER
High voltage can cause fatal injury.
Danger of severe or fatal injuries from electric shock or elec‐
tric arcs.
– Have a high-voltage technician (HVT) or a high-voltage
expert (HVE) de-energise the high-voltage system.
CAUTION
The high-voltage battery can become extremely hot. This can
cause injuries.
Take care not to burn your hands.
– Put on protective gloves.
NOTICE
Potential damage to vehicle
– Make sure that nobody is inside the vehicle after the high-
voltage battery has been removed.
The high-voltage battery 1 -AX2- will subsequently be referred
to as “high-voltage battery”.
Removing
– ⇒ Rep. gr. 93; Visual inspection of high-voltage battery 1
[AX2].
– ⇒ Rep. gr. 19; Draining coolant.
NOTICE
Potential damage to vehicle from slipping off.
– The dimensions of the vehicle support plates and their
spindles must be sufficient to ensure that the load that
is imparted centrally between the outer edge and centre
of the vehicle support plates can be supported. If the di‐
mensions are not sufficient, different vehicle support plates
must be used that meet this requirement.
Note
Not every lifting platform is suitable for the removal of high-volt‐
age battery. Ensure that there is sufficient clearance. When
lifting, ensure that there is sufficient clearance -a- around the
high-voltage battery so that it can be placed on the scissor-type
assembly platform -VAS 6131B-.
– Swivel lifting platform arm with vehicle support plate -1- up
to frame of high-voltage battery -2-. Then swivel back lifting
platform arm with vehicle support plate -1- far enough -a-
to allow for lowering high-voltage battery -2- in the following
step.
