specified by the LED assigned for BKR 1 Open. If the switching device is configured as
Contactor, then the SLD Contactor color is specified by the LED assigned for Contactor
Open.

Br
eaker (Contactor) and later the switching device is changed to Contactor (Breaker) then

eaker), otherwise previous Breaker
(Contactor) LED configuration will be applied to select the SLD Contactor (Breaker)
