Special tools and workshop equipment required
♦ High-voltage tool set -VAS 6762-
♦ Torque wrench -VAS 6883/1A-
♦ accidental contact protection -T10608-
♦ accidental contact protection insert -T10628-
♦ voltage tester -VAS 6762/45-
DANGER
Danger to life from high voltage.
Electric shocks or arcs may lead to serious injuries or death.
– Suitable personal protective equipment (PPE) must be
worn for the subsequent work steps.
– The subsequent work steps must be supervised by an
additional specialist with appropriate qualification.
– Outside the hazard area, the additional authorised special‐
ist can support the HVE as required within the scope of his
or her qualification.
Put on the required protective equipment for the subsequent
work steps:
♦ Arc flash resistant clothing (at least APC 2, at least 318 kJ)
♦ Helmet with arc flash resistant visor (at least APC 2, at least
318 kJ)
♦ Arc flash resistant gloves with nitrile glove liners (at least
APC 2, at least 318 kJ), insulating up to at least 500 V

Removing
– ⇒ Rep. gr. 93; Opening high-voltage battery 1 [AX2].
– Fit accidental contact protection insert -T10628- -A- onto
battery module 8 -J998- -2-.
– Unscrew bolts -3- on high-voltage connector -4- between
switching unit for high-voltage battery, positive terminal -
SX8- -1- and battery module 8 -J998- -2-.
– Detach high-voltage connector -4- between switching unit for
high-voltage battery, positive terminal -SX8- -1- and battery
module 8 -J998- -2-.
– Fit accidental contact protection -T10608- onto exposed
high-voltage connection on battery module 8 -J998- -2-
– Fit accidental contact protection insert -T10628- -A- onto
battery module 4 -J994- and battery module 5 -J995-.
– Unscrew bolts -1- on high-voltage connector -2- between
battery module 4 -J994- and battery module 5 -J995-.
– Remove high-voltage connector -2- between battery module
4 -J994- and battery module 5 -J995-.
– Fit accidental contact protection -T10608- onto exposed
high-voltage connection on battery module 4 -J994- and bat‐
tery module 5 -J995-.
Installing
– Fit accidental contact protection insert -T10628- -A- onto
battery module 4 -J994- and battery module 5 -J995-.

– Tighten bolts -1- from high-voltage connector -2- to specified
torque straightaway.
– Have an additional mechanic observe torque settings.
– Remove accidental contact protection insert -T10628- -A-.
– Fit accidental contact protection insert -T10628- -A- onto
battery module 8 -J998- -2-.
Note
If the measurement is taken before the last battery connector
has been installed, a voltage can be measured with the switch‐
ing unit for high-voltage battery, positive terminal -SX8- instal‐
led. If this is the case, a load can be applied by pressing both
buttons on the voltage tester -VAS 6762/45-. If the voltage test‐
er -VAS 6762/45- no longer indicates voltage when the load is
applied, the work sequence can be continued.
– Prior to installing high-voltage connector -4-, carry out volt‐
age measurement using voltage tester -VAS 6762/45-.
DANGER
Wrong installation of battery modules and module connectors.
Risk of severe injury or death due to short-circuit with electric
arc.
– Check battery modules and module connectors for proper
installation.
– Proceed with the work only if there is no voltage between
the battery terminals.
Important
•
When the load is applied, no voltage is displayed.
– Immediately tighten bolts -3- on high-voltage connector -4-
between switching unit for high-voltage battery, positive ter‐
