Conduct in the event of a malfunction
If MyReserve should enter into fault mode (Status LED il-
luminates ORANGE or RED) and none of the following cri-
tical states is present, switch the DC switch on the bottom
of the MyReserve to "0" and contact the technical service
of SOLARWATT. Leave the AC voltage supply switched on
in order to be able to notify the technical service of the
error status. An error catalog can be found in section 12.3
for troubleshooting and analysis.

Power supply
Make sure that at least the neutral
conductor and one phase conductor are
connected in connection field A, with the
neutral conductor connected to terminal
L3.
Make sure that at least the neutral
conductor and one phase conductor are
connected to terminal L2.
CAN bus not
connected
correctly
Make sure that the connections H, L and
GND from the ACS 63 are connected
correctly to the receiving device.
Make sure that the connections H, L and
GND from the ACS 50 are connected
correctly to the receiving device.
Error
Restart the ACS 63 by switching off the
corresponding circuit breaker and wait
at least 3 seconds before switching it on
again.
Restart the ACS 50 by switching off the
corresponding circuit breaker and wait
at least 3 seconds before switching it on
again. Or disconnect the neutral conduc-
tor at terminal N on the ACS 50 for 3 s.
Incorrect
measurements
Incorrect instal-
lation
Reconnect and re-commissioning the de-
vice, ensuring that the phase conductors
exit opening area D in the right rotation.
Repeat connection and commissioning,
ensuring that the phase conductors are
connected to the appropriate terminals
for L1, L2 and L3.
Two or more
phase conductors
interposed
Make sure that phase conductors L1, L2
and L3 in connection area D and A are
connected to the same phase.
Ensure that the arrangement of the
phase conductors L1, L2 and L3 with
connection to the terminals on the ACS
50 is correct.
If you are experiencing technical problems with the AC
Sensor, please use the service hotline. We will need the
following information to further assist you:
• Type and serial number of the AC Sensor (see type plate)
• Type and serial number of the device receiving the mea-
surements form the AC Sensor 63 on the CAN bus
• Provide as much detail as possible when describing the
error
