The performance of all electrical
work requires compliance with
the safety instructions provided
under Section 5, item 5.4, "Electrical connec-
tions".
Electrical connection and work
on electrical components may
only be carried out by authorised
electricians.
The relevant national and local regulations
and standards must be complied with dur-
ing assembly and electrical installation.
The design of the ventilation unit com-
plies with the safety requirements of the
Equipment and Product Safety Act and the
applicable provisions of the EC Directives.
•
The electrical connection must be estab-
lished in compliance with the correspond-
ing wiring diagram! (For more information
on this subject, please see the respective
wiring diagram in this section)
•
The cable cross-sections indicated are
minimum cross-sections for copper lines
and do not take the cable length or site
conditions into account.
•
Cable type, cable cross-sections and lay-
ing must be determined by an authorised
electrician.
•
Low-voltage cables must be laid sepa-
rately from mains cables; alternatively,
screened cables must be used.
•
The pre-fuse of the supply line must have
isolating characteristics.
•
A separate cable inlet must be used for
each cable.
•
Unused cable inlets must be hermetically
sealed.
•
All cable entries must be strain-relieved.
•
Potential equalisation must be put in
place between the unit and the air duct
system.
•
All safety measures must be tested fol-
lowing electrical connection.
(earth resistance, etc.)
•
In order to prevent the activation of
unsuitable residual current-operated pro-
tective devices, we expressly recommend
the use of earth leaking circuit breakers
that are sensitive to pulsating current or
AC/DC sensitive (type A or B) with delayed
tripping.

13.1 ELECTRICAL WIRING DIAGRAM
VOLTAGE SUPPLY AND LAN
CONNECTION
The heat pump combi unit is designed for a
voltage supply of 230 V/ 50 Hz. Connection
to the three-phase supply with 400 V/50 Hz
is not intended.
The terminals for the voltage supply are
located at the top of the unit in the electrical
connection box (see Section 11, page 24,
item 25). Open the electrical connection box
and establish the voltage supply in compli-
ance with the following wiring diagram.
In order to connect the heat pump combi
unit with the Internet and furthermore with
the Pichler app or with Pichler Connect (re-
mote maintenance) a LAN cable connection
must be established.
A sticker is attached to the LAN sockets,
which can be removed. When you remove
this sticker and establish an Internet con-
nection, we assume that you agree with our
current privacy statement (see: http://www.
pichlerluft.at/datenschutz.html).
Upon completion, the cables must be fixed
using corresponding strain relief.
