13. Allow the charging unit to download software
settings.
14. Do a functional test of the charging unit. Refer to

product, page 41 .
6.8 PME - PROTECTIVE MULTIPLE EATHING
(UK VERSIONS ONLY)
Some variants of charging units are equipped with
Protective Multiple Earthing (PME) protection. By
monitoring the phase voltage, a fault in the grid-
connected earth connection (PEN conductor) can be
detected. Detection level is phase voltage <207 V OR
>253 V. In case of detected fault, any charging is
stopped, the EV is isolated (Live, Neutral and PE). The
charging station indicates blinking red.
Action when triggered:
(A red, slow blinking (0.5 Hz) indication on the
charging station LED, an error message can be read in
the GARO Connect app). A notification is sent to the
user and the owner if configured.
1. Disconnect the EV.
2. Contact the installer to investigate the root cause of
the problem. Reset the circuit breaker.
3. Press the test button marked “T” to conduct a ground
fault test. The circuit breaker should then trip. Refer to
6.4 To do an earth fault test, page 89 .
If the test is OK and no further uncertainty exists, then
the charging station can be used in normal operation.
The voltage level can be monitored in the GARO
Connect app.
CAUTION
Never use the charging station if any uncertainty exists
regarding PEN status or voltage levels.
6.9 SERVICE
The owner of a location is responsible for keeping the
installation in a safe condition. One recommended way
to fulfil this is to set up a service agreement with a
service provider.
CAUTION
Service must only be performed by approved
personnel.
Contact GARO to set up a service agreement.
6.10 REPAIR
CAUTION
All repair work must be done by GARO approved
