Starting the EFX48
When dc power is applied to the EFX48 (via the rear power connector) the start-up sequence
begins.
Any loads that are configured to connect will do so in a staggered sequence. Once connected
each load output’s LED will be illuminated solid green. If there is any reason why the loads
cannot connect (for example the internal temperature is too high or the bus voltage too low)
then the loads will be pending and their LEDs will flash at 1Hz.
Any strings that are configured to connect will do so in a staggered sequence. Once connected
each string’s LED will be illuminated solid green. If there is any reason why the strings cannot
connect (for example the string voltage is too low) then the strings will be pending and their
LEDs will flash at 1Hz whilst the system tries to establish correct conditions for connecting the
strings.
