Renewable energy supply
IMPORTANT (NOTE)
• Before making connections, check the Data label to
confirm power supply requirements.
• External earth (ground) boss
must
be connected to
earth (ground) rod or a local electrical earth.
• Renewable energy generators do not operate at
maximum capacity. Wind turbines are affected by
low wind speeds and solar panels by coatings of
dust, wildlife droppings and short daylight periods
in winter.
For these reasons, in some installations, generators
with a capacity greater then the specified 5 W
minimum should be used. Contact ABB for a
technical note, giving guidance on the selection of
suitably sized generators for AquaMaster4.
Renewable energy supply requirements:
• Input 12 V (nominal)
• V in: max. 32 V DC, min. 6 V DC
• Solar panel or wind generator 5 W or greater
