4. OPERATIONS
After all cables have been connected, and power source is available at the input
terminals, the ELI is ready to operate. Before turning on any switch or breaker, once
again check the following:
(a) Check that the input voltage conforms to the ELI’s rated input voltage.
(b) Check that the input frequency conforms with the ELI’s rated input
frequency.
(c) Check that the load at the output is switched off.
(d) Check that all breakers and the battery disconnects are opened.
(e) Check that no foreign material is inside the ELI.
4.1. Startup Procedure
To start the ELI from complete shutoff to normal operation, follow the steps below
to turn on the ELI.
(a) In case there is an extra input breaker for some special specification, please close
the input breaker first.
(b) Close the reserve breaker – The reserve and output LED on the mimic panel will
light up, indicating the reserve static switch loop is energized. Therefore the output
has power now. The supply of power in the ELI is established and the fans will
operate.
(c) Close the rectifier breaker - The rectifier will be automatically started if the power
source connected is correct. Wait 30 sec for DC bus voltage to rise until the
warning LEDs of “BAT LOW” and “BAT LOW STOP” go off (on the front
panel). Now, the DC is already ready for the inverter.
(d) Close the (optional) battery breaker - For safety purposes, a breaker (or fuse) is
employed between the batteries and the DC bus. Now the batteries will take over
to supply the DC bus if rectifier mains fail.
