13. Allow the charging unit to download software
settings.
14. Do a functional test of the charging unit. Refer to
4.12.15 To do a final functionality test of the
product, page 36 .
6.8 PME - PROTECTIVE MULTIPLE EATHING
(UK VERSIONS ONLY)
Some variants of CU is 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. The function is activated by
default on CU with this function. An installer can disable
the function.
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 79 .
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

installation in a safe condition. One recommended way
to fulfil this is to set up a service agreement with a
service provider.
CAUTION

personnel.
Contact GARO to set up a service agreement.
