GRID CONNECTION

The fans can only be opera-
ted in symmetrical (permitted
unbalance smaller than 2%)
and in neutral point earthed
networks, e.g. TN-S, TN-C,
TN-C-S, TN.

Connecting the potential
equalization system to all
conductive parts

Supply voltage tolerance
must be met

pin assignment.

Usage of fans only at grids in
which the THD percent smal-
ler than 10% is. THD = Total
harmonic Distortion. This va-
lue applies between the pha-
ses (L1-N) and the phases PE
(L1-PE).

To high voltage can may de-
stroy the motor

The nameplate information
shall be observed (voltage,
frequency, temperature ran-
ge, circuit diagram)

Grid connection according to
the connecting conditions
and the respective regulati-
ons.

The control wire of the unit
cannot be laid parallel to the
grid connection. A large dis-
tance (>>10cm) should be
ensured.
Protection:
The connection to the low-
voltage network must be do-
ne according to DIN VDE
0298-4.
Assignment of conductor cross-
section and the fuse protection
required for them (overload protection only, no device protec-
tion).
