9.0 Influence of reverse voltage or induced voltages of glow lamps / energy-saving
lamps / LED / room lighting and the like
Our units comply with the latest regulations, see section 1.4. Reverse voltages or induced voltages are not
“
faults
”
.
They can occur depending on the installation and fan / switch / lighting combination and they can cause undesired
symptoms, such as glowing, misfires and malfunctions.

REVERSE VOLTAGE STANDARD TYPES without internal electronics
For multi-speed types, there is reverse voltage at the other non-switched terminal.
In general, room lighting / glow lamps / LED must only be connected via 2-pole switches.
The capacitor measure is not possible in this case! (see
SS-1011
).
–
REVERSE VOLTAGE ELEKTRONICS TYPES (N, NC, P, PC, F)
As a result of the internal electronics in the fan, there is “low-energy” reverse voltage at the switch input (always the highest level
for multi-speed types). A damping measure with an X2 capacitor can be implemented at the “electronic” switch input (always
the highest level for multi-speed types) to suppress the reverse voltage. For multi-speed types, the capacitor measure is not
possible at the respective lower levels.
–
GLOW LAMPS / LED
In order to prevent permanent glowing when using a glow lamp / LED in the switch, a customer-provided capacitor can be
used in parallel to the fan switch input (see
SS-1010
).
– (X2 capacitor with 0.33 µF/275 V~ with wire, Ref. no. 84955-001).
–
ROOM LIGHTING WITH ELECTRONIC CONTROL
e.g. energy-saving lamps or LED lamps at the switch input
In order to prevent faults in the lamp (e.g. misfires or flickering) when using an “electronically” controlled lamp at the switch
input, a customer-provided capacitor can also be used in parallel (
SS-1010
).
– (X2 capacitor with 0.33 µF/275 V~ with wire, Ref. no. 84955-001)
Alternatively, the lighting must be connected via a 2 pole switch (
SS-1011
).
