5 Information for qualified electricians
5.1 Fitting and electrical connection
DANGER!
Electrical shock when live parts are touched.
Electrical shocks can be fatal.
Before carrying out work on the device or load, disengage all the
corresponding circuit breakers. Cover up live parts in the working environment.
Fitting the transformer
Ensure adequate installation space for heat dissipation. In critical cases, carry out temperature
measurement. The housing temperature at the tc point (see transformer label) must not be
exceeded.
Do not fit in the vicinity of heat sources, e.g. lamps.
o
Loosen screws (1) and remove terminal covers (3).
o
Fasten transformer with screws through mounting holes (2).
Connection instructions
The transformer can be operated either with a DALI control unit or an installation button.
Operation with a DALI control unit and and installation button at the same time is not possible.

i
Do not connect secondary cable with additional transformers (Figure 2).
i
Do not lay secondary cable parallel to mains cable or transformer (Figure 2).
i
Do not lay secondary cable on metal surfaces.
i
Ensure that the control cable is of the appropriate type, cross-section and routing for the
VDE specifications for 250 V cables, DALI interface has basic insulation.
i
For reliable strain relief, use only cables of the same type on the primary side and on the
secondary side.
