3.7.3 Basic insulation
IEC 61347 demands basic insulation between the control circuit and
mains supply for control inputs. The DALI standard (IEC 62386) is
related to this. Consequently, the DALI line is “only” basically insulated
and must be treated like the mains voltage for this reason as is the
1…10 V interface.
3.7.4 Lamp holders
The lamps must be mechanically secure and make contact in the
lamp sockets. The holders must be selected according to the type of
ECG/lamp used.
3.7.5 Master/slave circuit
(2-lamp ECG for the operation of 2 single luminaires) Master/slave op-
eration with multilamp dimmers is not permitted. This is because of
the capacitive leakage currents that can lead to imbalances, different
luminances and unstable operation in the dimmed state (flickering).
3.7.6 Minimum reflector gaps
The reflector must never rest on the lamp, otherwise this can lead to
vibrations and noise emissions. A minimum gap of 6 mm must be
maintained between the lamp and the reflector in all luminaires. If the
gap is less, this can lead to different brightnesses along the length of
the lamp due to the capacitive leakage currents. Flickering can also
occur.
