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.

Electric rear-wheel drive EIP220 and all-wheel drive EIA200, EIP220 - Edition 11.2021  
– 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 12 -J1002- -4-.  
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 -2- on high-voltage connector -3-  
between switching unit for high-voltage battery, positive ter‐

Note  
The battery regulation control unit -J840- and switching unit  
for high-voltage battery, negative terminal -SX7- are calibrated  
together in the factory.  
Important  
The battery regulation control unit -J840- and switching unit  
for high-voltage battery, negative terminal -SX7- must be  
renewed together ⇒ Rep. gr. 93; Removing and installing
