Interference Suppression
A novel electronic interference suppressor replaces the
former conventional interference suppression choke.
Consequently, this is a "low-noise" dimmer.
If questions concerning the measurement of radio
interference, please contact Busch-Jaeger Elektro
GmbH in Lüdenscheid direct.
The S and G lines shall be considered as internal
connecting lines and shall be kept as short as possible
(see Technical Data).
Capacity Expansion
When operated with power module 6594U-500 (see
Fig. 3), the controlled outputs must be linked in order to
safeguardall the protective functions of the dimmer
system.
