Tilt sensor (optional) connection

The tilt sensor device, when is activated (tilt more than 10°), allows to disconnect the main AC input voltage. The
undervoltage release, connected to the tilt sensor, is de-energized and the main AC circuit breaker opens.
The tilt sensor has a contact that is closed when the tilt sensor is de-enenergized and there is no tilt detected.
NOTE
The manufacturer recommends to use and an uninterruptible power supply for the 24 V DC, to
prevent tripping of the branch circuit breaker.
The circuit breaker, 24 V DC power supply delivered from an UPS and all other external
components to the EVSE are not within the scope of ABB E-mobility, therefore are not provided.
NOTE
The owner is responsible for considering a voltage drop on the 24 V DC circuit.
The owner must make sure that the undervoltage release of the branch circuit breaker receives
the correct input voltage according to the required specifications.
NOTE
Refer to
The illustrations shows the tilt sensors interface with the power distribution system of the site.
