Stationary Operation/Neutral Position

In stationary operation/neutral position, the electronic disconnecting switch is in "Sleep mode". A closed-circuit current of > 1 mA is essential for this. The electronic disconnecting switch is always open in stationary operation/neutral position. The closed-circuit current flows exclusively via the system battery (55 Ah). This prevents the starter battery (110 Ah) from discharging via the vehicle electrical system. The electronic disconnecting switch is activated either with detection of terminal 15 or at a battery voltage of > 13.5 V (charging operation).
