Danger of electric shock
The following components of the boiler are connected to a 230 V
power supply:
(Electrical connection for) circulating pump
(Electrical connection for) gas combination block 230 RAC
(Electrical connection of) fan
The majority of components in the control unit
Ignition transformer
Power supply cable connection
Various connections in the connection box
The boiler has a three-wire mains lead (lead length 1.5 m) and is suitable
for a 230 VAC/50 Hz power supply with a phase/neutral/earth system. The
boiler is not phase sensitive. The boiler is completely pre-wired.
Caution
Always order a replacement mains lead from Remeha. The
power supply cable should only be replaced by Remeha, or by
an installer certified by Remeha.
The switch must be easily accessible
Use an isolating transformer for connection values other than
those stated above.
The control panel and the connection box still need to be fitted. The PCBs
are also placed in the connection box.
