7.4 Tilt sensor (optional)
The tilt sensor connections allow to connect the circuit to enable AC circuit breaker tripping mechanism during
activation of EVSE tilt sensors. When the tilt sensor is activated (tilt more than 10°) the undervoltage release in the
branch circuit breaker that supplies power to the EVSE is de-energized and the branch circuit breaker opens.
NOTE
The manufacturer recommends to use and an uninterruptible power supply for the 24 V DC, to
prevent tripping of the branch circuit breaker.
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.
The illustration shows the tilt sensors interface with the power distribution system of the site.

Tilt sensor. The tilt sensor has a contact that is closed when the tilt sensor is de-enenergized and
there is no tilt detected. When the contact is closed, the output is 20-24 V DC. When the contact is
open, the output is 0 V DC.

Undervoltage release.
The breaker will trip in the event of loss of voltage to the undervoltage release (I) It is possible to
install tilt sensors afterwards. Ask ABB E-mobility B.V. Refer to section About this document.
NOTE
The shown branch circuit breaker, 24 V DC supply delivered from an UPS and all other
components are not within the scope of ABB E-mobility, therefore are not provided in the EVSE.
