WARNING Electrocution
The power cable must only be replaced (for example
if damaged) with an original spare part by a qualified
contractor authorised by the manufacturer (connection
type X).

10.5.2 Connection options: Operation with external switching
device that interrupts appliance power supply
To ensure cylinder corrosion protection, appliances are equipped
with a maintenance-free impressed current anode as standard. A
maintenance-free impressed current anode, when compared to a
sacrificial anode, offers the greatest protection and saves on costs
for maintenance that would otherwise be required. To ensure cyl-
inder corrosion protection however, the impressed current anode
must be supplied with power permanently.
If the device is to be used with external switching devices (e.g.
external time switch, switched socket, energy management sys-
tem, power-interrupting signal from the power supply utility)
that interrupt the appliance power supply, the impressed current
anode must not be subject to the effects of such devices, but sup-
plied independently. For such cases, the appliance allows separate
power supplies for load (compressor) and electronic (including
impressed current anode) circuits.
f Remove the appliance cover (see chapter "Cleaning and f
maintenance / Removing the appliance cover").
