(1)
forward.
3.
Undo the clips
(3)
from the brackets.
4.

5.4.1.2 Closing the electronics box
1.
Close the cover
(2)
by pushing downwards on the elec-
tronics box
(1)
.
2.
Ensure that all the clips
(3)
audibly click into the brack-
ets.
3.
Hinge the electronics box upwards.
5.4.2
Establishing the power supply
Caution.
Risk of material damage due to high con-
nected voltage.
At mains voltages greater than 253 V, elec-
tronic components may be damaged.
▶
Ensure that the nominal voltage of the
mains is 230 V (+10%/-15%) ~ 50 Hz.
1.
Observe all valid regulations.
2.
Open the electronics box. (

3.
Provide one common electricity supply for the boiler
and for the corresponding controller:
–
Power supply: Single-phase, 230 V, 50 Hz
–
Fuse protection:
≤
3 A
4.
Connect the product using a fixed connection and a
partition with a contact opening of at least 3 mm (e.g.
fuses or power switches).
5.
Use a flexible line for the mains feed line, which is
routed through the cable duct into the product.
6.
Carry out the wiring. (

7.
Observe the connection diagram (
→
Page 45).
8.
Screw the supplied ProE plug to a suitable, flexible
three-core mains connection cable which complies with
the relevant standards.
9.
Close the electronics box. (

10. Make sure that access to the mains connection is al-
ways available and is not covered or blocked.
5.4.3
Carrying out the wiring
Caution.
Risk of material damage caused by incor-
rect installation.
Mains voltage at the incorrect plug terminals
on the ProE system may destroy the elec-
tronics.
▶
Do not connect any mains voltage to the
eBUS terminals (+/-).
▶
Only connect the power supply cable to
the terminals marked for the purpose.
1.
Route the supply lines of the components to be connec-
ted through the cable duct provided on the underside of
the product.
2.
Use the strain reliefs provided.
3.
Shorten the supply lines as necessary.
4.
To prevent short circuits if a strand accidentally comes
loose, only strip the outer sheathing of flexible lines to a
maximum of 30 mm.
5.
Ensure the inner conductor insulation is not damaged
when stripping the outer sheathing.
6.
Only strip inner conductors just enough to establish
good, sound connections.
7.
To avoid short circuits resulting from loose individual
wires, fit conductor end sleeves on the stripped ends of
the conductors.
8.
Screw the respective ProE plug to the supply line.
9.
Check whether all conductors are sitting mechanically
securely in the terminals of the ProE plug. Remedy this
if necessary.
10. Plug the ProE plug into the associated PCB slot.
11. Secure the cable in the electronics box using the strain
reliefs.
