Attention: Electrical equipment must be installed and fitted by
qualified electricians only.
Not suitable for safety disconnection of the load.
Switching off the dimming actuator does not isolate the load
electrically from the mains.
When using conventional transformers, each transformer must
be protected with a fuse on the primary side as specified in the
manufacturer's instructions.
Use only safety transformers as per DIN VDE 0551.
Do not connect capacitive loads (e.g. Berker Tronic trans-
formers) together with inductive loads (e.g. conventional
transformers) to one and the same output.
Any non-observance of the safety instructions may cause fire
or other hazards.
Safety instructions
Important information
• With conventional transformers, the resistive part of the load must
not exceed 50 %.
• After full utilization of the dimming actuator, the capacity can be
further enlarged by connecting up to 10 power boost units to
each channel.
• With Berker Tronic transformers: use Berker Tronic power boost
units (built-in or DIN-rail models).
• With conventional transformers: use LV power boost units
(built-in or DIN-rail models)
• Observe the technical connection guidelines of the power supply
companies.
• Centralized telecontrol signals from power supply companies may
cause brief flickering of the lamp in low dimming positions.
