Caution.<br />
Risk of damage caused by incorrect<br />
installation.<br />
A mains voltage at the incorrect plug terminals<br />
on the ProE system can destroy the<br />
electronics.<br />
> Only connect the mains connection cable<br />
to the terminals marked for the purpose.<br />

Caution.<br />
Risk of damage caused by incorrect<br />
installation.<br />
Connecting wires that have been stripped<br />
too far can cause short circuits and damage<br />
the electronics if a strand accidentally<br />
comes loose.<br />
> Only strip the outer sheathing of flexible<br />
cables for a maximum of 3 cm to prevent<br />
short circuits.<br />
> Lay the lines correctly.<br />
> Use strain reliefs.<br />
i If<br />
you install the boiler in safety area 2, it can<br />
only be operated if it is room sealed. Installation<br />
method B53P is not permitted in this case.<br />
Observe the latest edition of the "IEE Wiring<br />
Regulations – BS7671, Requirements for Electrical<br />
Installation".<br />
In IE, reference should be made to the current edition of<br />
the ETCI (Electro-Technical Council for Ireland) rules.<br />
The boiler is supplied for connection to 230 V, ~ 50Hz supply<br />
fused at 3 A rating. Connection to the mains supply<br />
shall be made via a fused 3 pin plug to an unswitched shuttered<br />
socket, both complying with the requirements of<br />
BS 1363. (Alternatively, connection may be made via a 3 A<br />
fused double pole isolator having a contact opening of at<br />
least 3 mm in all poles and supplying the boiler and controllers<br />
only). The point of connection to the mains supply must<br />
allow complete electrical isolation of the boiler and its ancillary<br />
controllers. It should be readily accessible and adjacent<br />
to the boiler. A flexible cord fulfilling BS6500 or comparable<br />
standard, conductor diameter between 0,75 and 1,5 mm 2<br />
and an allowed temperature range including 90 °C should<br />
be used.<br />
The nominal voltage of the mains must be 230 V; at mains<br />
voltages greater than 253 V and less than 190 V the functions<br />
may be impaired.<br />
> Open the electronics box (¬ section 8.2).<br />
> Use a normal commercial mains connection cable that is<br />
compliant with standards.<br />
> Route the mains connection cable through the left cable<br />
duct (¬ fig. 8.1, pos. 4) on the base of the boiler.<br />

> Use the strain reliefs (1) <strong>pro</strong>vided.<br />
> Shorten the mains connection cable as necessary.<br />
> Only strip the outer sheathing of flexible cables to a<br />
maximum of 3 cm.<br />
> Ensure inner conductor insulation is not damaged during<br />
stripping of outer sheathing.<br />
> Only strip inner conductors sufficient to make good<br />
sound connections.<br />
> Fit the stripped ends of the conductors with crimp pin<br />
terminals to ensure a secure connection free from loose<br />
strands to prevent short circuits.<br />
> Connect the <strong>pro</strong>vided green ProE plug for the mains<br />
connection to the mains connection cable using a screwdriver.<br />
> Insert the ProE plug into the corresponding PCB slot<br />
(L, N and earth) (¬ fig. 8.2).<br />
> Lay the lines correctly.<br />
> Secure the cable in the electronics box using the strain<br />
reliefs.<br />
> Close the electronics box (¬ section 8.2).<br />
i Make<br />
sure that the connection cables are<br />
securely fastened to the plug terminals.<br />
