10.5 Electrical connection

WARNING Electrocution
Carry out all electrical connection and installation work
in accordance with national and regional regulations.
WARNING Electrocution
If the appliance is permanently connected to the power
supply, ensure that the appliance can be separated from
the power supply by an isolator that disconnects all poles
with at least 3 mm contact separation. Contactors, circuit
breakers or fuses can be used for this.
WARNING Electrocution
f Observe the safety measures to prevent contact f
with dangerously high contact voltage.
WARNING Electrocution
Coming into contact with live components presents a
threat to life. Disconnect the appliance from the power
supply before carrying out work on the control panel.
Prevent the power supply from being switched on while
you are working on the system.
WARNING Electrocution
Insufficient earthing can lead to electrocution. Ensure
the appliance is earthed according to locally applicable
requirements.
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").
