Installation
WARNING Electrocution
Insufficient earthing can lead to electrocution. Ensure
the appliance is earthed according to locally applicable
requirements.
WARNING Electrocution
If the power cable is faulty, replace it with a new one.
The power cable should only be replaced by a qualified
contractor.
!
Material losses
The specified voltage must match the mains voltage. Ob-
serve the type plate.
!
Material losses
Observe the MCB/fuse protection required for the appli-
ance (see chapter "Specification/ Data table").

Never connect the appliance to the power supply before
the DHW cylinder is filled.
The appliance is supplied with a flexible power cable without plug.
If the power cable is not long enough, unclamp it from the
appliance. Use a suitable installation cable.
When routing the new power cable, ensure that it is water-
proof as it passes through the existing cable grommet. Con-
nect the connecting cable properly inside the appliance.

10.3.2 Separate power supply to the impressed current anode
At the factory, the appliance is fitted with rechargeable batteries
that ensure the power supply to the impressed current anode in
the case of a power failure. If regular interruptions to the power
supply are not anticipated, the batteries will require no mainte-
nance.
Every three years the batteries must be replaced for the impressed
current anode in the following cases:
- The impressed current anode is not connected separately to
a continuous power supply source and a switching contact
regularly interrupts the power supply to the appliance.
- The security of supply is inadequate.
Neglecting to do this puts the appliance at risk of damage.
Replacing the batteries can be avoided by connecting the im-
pressed current anode separately to a continuous power sup-
ply source. This continues to protect the DHW cylinder against
corrosion if the rest of the appliance is switched off, e.g. when
connected to a controlled power supply.
Remove the appliance cover (see chapter “Cleaning and
maintenance/ Removing the appliance cover”).

Prepare the electric cables in such a way that each cable ter-
minates with a wire ferrule.
Push the cables through one of the cable entries in the appli-
ance casing.
Route leads through the strain relief.
Remove the jumper which leads from X0/N to X0/2 in the de-
livered condition.
Remove the jumper which leads from X0/L to X0/1 in the de-
livered condition.
