NOTICE
The unit will be damaged through
contact with components at risk of ESD
on the electronics board of VZ, VZ 15,
GVZ, VZC, GVZC EC, F, I, H and RC
units.
Avoid direct touching of the components
or contact surfaces.
NOTICE
Damage to the unit if connected
incorrectly. For example, if an electric
load is connected to terminal 4 or if
connected to 2 phases.
Connect the unit as shown in the wiring
diagrams in chapter 22.
Do not connect additional consumers
to terminal 4.
Information
●
Always note the relevant specifications for
electrical installations and when installing
equipment. In Germany particular attention
must be paid to the DIN VDE 0100 and the
corresponding parts. In rooms with baths
or shower units, for example, this would be
Part 701.
●
The electrical connection is only permitted
by trained electricians.
●
The electrical connection can be undertaken
upon installation of the ER-UP housing.
●
Observe ambient conditions (
chapter 8)
and technical data (
chapter 9).
●
Note permitted duct cross-section of
max. 1.5 mm².
●
Only connect the unit to a permanent
electrical installation.
●
The degree of protection is only
guaranteed:
● if installation is undertaken correctly,
● if the power cable is correctly guided to
the intended cable grommet,
● if fan unit is correctly engaged in
ER-UP housing and
● if cover [15] is closed and engaged.
13.1.1 Connect the unit electrically
1. Switch off mains fuse, secure and fit
warning sign.
2. Remove plaster protective cover.
3. Cut off and insulate PE conductor and
individual cable cores that are not
required!
4. Remove power cable surround and cut
to length according to Figure 15.
5. Wire power cable to the terminal box
according to the wiring diagram in
Chapter 22.
6. Mark the fan type on the wiring diagram
in the recess-mounted housing.
This prevents mistakes during final
installation, for example, if different
fan inserts are fitted in the system.
7. Insert plaster protective cover.
We recommend keeping these
mounting and operating instructions
until final installation in the ER-UP
housing.
