Working on the system
■ Isolate the system from the power supply (e.g. by removing the sepa­rate fuse or by means of a mains iso­lator) and check that it is no longer 'live'.
■ Safeguard the system against recon­nection.
■ Where gas is used as the fuel, close the main gas shut-off valve and safe­guard it against unintentional reopen­ing.
■ National installation regulations
■ Statutory regulations for the preven­tion of accidents

Power supply

Connect accessories with a total wat­tage above 400 W directly to the mains power supply.
5443 825 GB
Danger
Incorrectly executed electrical installations can result in injuries from electrical current and dam­age to the appliance.
Connect the power supply and implement all safety measures (e.g. RCD circuit) in accordance with the following regulations:
■ IEC 60364-4-41
■ VDE regulations
27
Page 28
Extension kit with mixer PCB
■ Connection requirements specified by the local power supply utility
■ Protect the power cable with a fuse/MCB of up to 16 A.
Danger
The absence of component earthing for the system can lead to serious injury from electric current if an electrical fault occurs. The appliance and pipework must be connected to the equi­potential bonding of the building.
(cont.)
■ The mains isolator (if installed) must simultaneously isolate all non­earthed conductors from the mains with a minimum contact separation of 3 mm.
■ If no mains isolator is installed, all non-earthed conductors must be iso­lated from the power supply by the upstream circuit breaker with a mini­mum contact separation of 3 mm.
■ In addition, we recommend installing an AC/DC-sensitive RCD (RCD class
B ) for DC (fault) currents that can occur with energy efficient equip­ment.

Danger
Incorrect core assignment can result in serious injury and dam­age to the appliance. Never interchange cores "L" and "N".
Please note
Incorrect phase sequence can
!
cause damage to the appliance. Ensure phase equality with the control unit power supply.

Changing the rotational direction (if required)

1. Danger
An electric shock can be life threatening. Before opening the boiler, disconnect it from the mains voltage, e.g. at the fuse or mains isolator.
Remove the casing cover (see chapter "Overview of electrical con­nections").
2.
Switch cores BK and BK on plug gS.
3. Refit the casing cover.
4. Check the rotational direction.
