2.5.9 Power connection
Notify your local power supply company
of the electrical connection. Only qualified
electricians must carry out the installation in
accordance with these instructions.
Before any work, isolate the
equipment from the power supply at
the control panel.
Route power supply and control cables/leads
separately.
Observe VDE 0100 [or local regulations] and
the regulations of your local power supply
company.
The ventilation equipment must be able to be
separated from the mains power supply by an
additional isolator, which disconnects all poles
with at least 3 mm contact separation. For
this purpose, use contactors, mains isolators,
fuses, etc. on site.
The terminals are located beneath the
lower front facia, top right hand side. When
removing the front facia ensure that the earth
cable is not ripped off the front facia (Fig. 7).
If necessary, remove the cable from the blade
terminal.
When replacing the front facia ensure
that the earth cable is correctly
connected.
Route all connecting cables and sensor leads
through the apertures in the back panel
(Fig. 9 pos. 20).
After connecting all electrical cables, refit and
seal the cover over the terminal strip (Fig. 12).
