H2O Manual | 14
Fuses should only be replaced with the original
size / specification devices. Failure to do so
could result in dangerous electrical failure and
will invalidate any warranty claim.
Temperature probe
Due to the nature of the probe, it is important
that it is very carefully handled, installed and
well routed. In particular, ensure that the probe
fits the thermal pocket and that it is not too tight,
which may cause damage to its insulation. In
addition, the tip of the probe should also be
protected and carefully managed. If the insulation
of the conductors or the tip is damaged, the
Synapse H2O will enter an error state which
can be identified by the red “Temp Error” LED
just above the probe’s PCB connector. If this
LED illuminates, it is likely that the probe is
damaged. Remove the probe and inspect it for
insulation damage and, if necessary, replace it.
DC leakage current
The H2O is fitted with a DC residual current
sensor. It is designed to detect DC current
leakage above 30mA in the PV array and, in the
case of DC leakage, it will shut the Synapse H2O
down into a safe state. In such circumstances,
the DC array should be treated with great care
and the fault located and corrected urgently.
6.7 Service, support and repairs
If the H2O is damaged, becomes faulty or in any
way fails to work correctly, it will require repairs
by Rubicon.

7. Mobile applications and
WiFi connectivity
7.1 APP introduction
The Synapse H2O can be commissioned,
configured and monitored via the included
Mobile applications. The applications are
known as Web Apps, which means they are
web based and so the same App works on both
Android and iOS devices. The applications can
be viewed as web pages or installed and work
just as any other app. They can be downloaded
at www.rubiconsa.com/H2O.
Installing the Synapse H2O’s App
After opening one of the provided links in a
mobile device’s web browser, depending on
your browser / device, you can install the Web
app to your home screen, just like any other
app. The process for this varies from browser to
browser, but the general idea is the same. Here
are the instructions for popular web browsers.
After loading the link in the browser:
Android devices
»
Firefox: you’ll see a “home” icon with a plus (+)
icon inside it — this is the “Add to Home screen”
icon. Tapping this will show a confirmation
banner and then tapping the banner’s big “+
ADD TO HOME SCREEN” button completes
the action, adding the app to the Home screen.
Note that in Android 8 and higher an “Add to
Home screen” permission request will be shown
first.
»
Samsung Internet: you’ll see a circular
icon with a downward facing arrow next to
the address bar. Tapping the icon will show a
confirmation banner. Tap the “+ ADD TO HOME
SCREEN” button to add the app to your home
screen.
»
Chrome for Android: You’ll see an install
banner pop up asking whether you want to add
this app to your Home screen. If you choose not
to add it to your Home screen at this point, you
can do so later using the “Add to Home Screen”
icon in the main Chrome menu.
»
Other browsers: Using the 3 dot drop-down,
tap “Install app” in the menu list.
