		Model 211.2	AR54.10-P-0003TA
		Model 219.3	AR54.10-P-0003TX
2	Detach positive terminal cover on battery (G1), turn it by 180° and attach again
3	Connect on-board ground line to negative terminal of battery disconnect switch (1)
4	Clip positive terminal (3) of battery disconnect switch (1) onto positive terminal of battery (G1) and fix in place if necessary
5	Position battery disconnect switch (1) at battery (G1)	Position the battery disconnect switch (1) in such a way that it cannot cause noises while the vehicle is in motion.
6	Route wiring harness (4) of battery disconnect switch (1) in luggage compartment and guide sensor with display unit (5) out of luggage compartment on left-hand side	The outboard part of the wiring harness (4) together with the sensor with display unit (5) must be approx. 15 cm.

The battery disconnect switch (1) is closed and the on-board power supply voltage is applied. The LED on the sensor with display unit (5) flashes. If the alternator voltage is applied (engine running), the LED on the sensor with display unit (5) remains lit. Deactivating the on-board electrical system:  Hold the solenoid at the sensor with display unit (5) for approx. 5 s. The battery disconnect switch (1) is opened and no on-board power supply voltage is applied. The LED on the sensor with display unit (5) does not light up. The battery disconnect switch (1) is opened automatically if it has remained inactive for approx. 90 min.
