Connector for:
- closing pushbutton
- opening pushbutton
- luminous “READY” signal
Connector for input signal of
the circuit breaker
open/closed position sensors
Jumper only present in the full
option version.It is not normally
short-circuited and energy
consumption during capacitor
charging is 100 W.If it is short-
circuited, energy consumption
during capacitor charging is
reduced to 50 W (the charging time
is obviously doubled)

N.B. Changing the settings by means of dip-switches must be
carried out with the control module de-energised and the
capacitor discharged since the selections set and/or modified
are acquired by the control electronics at the moment it is turned
on.
I1002-2 “off” & JP1017 “assembling”:
fast setting (10ms)
I1002-2 “off” & JP1017 “cutted”: slow
setting (20ms)
I1002-2 “on” very slow setting (43ms)
Operating time setting
With ANSI version only the Dip-switch I1001 (cally I1) for UV
thresholds adjustment is mounted on a different board:
KM1005B is to be
considered in place
of KM1005.
