STARTERLESS OPERATION
A = External starting strip
D = Choke
DD = Double choke
H = Heating transformer
K = Compensation capaci-
tor (if required)
K1 = Series capacitor
K2 = Capacitor
KE = Radio interference
capacitor 10 nF
LL = Fluorescent lamp
St = Starter
St1 = Starter
1)
UN = Line voltage
V = Control gear
W = High ohmic resistor
(built into lamp base)
Z = Capacitor starting aid
1) Prolonged ignition times, especially at
low voltage, can be shortened by rotat-
ing one of the starters through 180°
