The electrical connection of the load measured (3) to the anode (1), is made through the wiring of connection (6):
- To the anode: U shaped terminal M10 (4)
- To the load measured: female Faston terminal 2.8 (10)
The electrical connection of the load measured (3) to the earth, is made through the wiring of connection (7):
-To earth: U shaped terminal M10 (5)
- To the load measured: female Faston terminal 6.3 (10)
caution
Check the magnesium anode load periodically by pushing the button. If the gauge is in the red zone, the

All the Hitachi DHWT can be equipped with the permanent cathode protection system which is totally automatic and
maintenance free.
It basically comprises a titanium anode (1) mounted on the storage tank’s connection plate (2) and connected to a
potentiostat (3) which automatically regulates the input current to the anode, constantly measuring the potential of the
storage tank), through the leads (4).Wiring the anode to the potentiostat by means of leads (4) is carried out in the following
way:
-To the anode: connection (5), female Faston terminal.
