5-1 Start up procedure
5-1-1 Initial start up procedure
(1) Introduction to switches inside the equipment and its function
S1 Switch: auxiliary switch
S2 Switch: secondary input power switch or BYPASSS switch for the model with input
transformer.
S3 Switch: main input power switch
S4 Fuse Switch: power switch of the equipment
S5 Switch: equipment switch
S6 Switch: manual bypass switch used when maintaining the equipment
(2) Input phase sequence testing:
Turn on the switchboard to deliver power to the input terminal. Measure the voltages on each
point to see if it is within the specifications of this equipment.
Then use a 3-phase sequence meter to check the input sequence. If phase sequence is correct,
proceed to next step. On the contrary, if phase sequence is reversed, turn off external power
switch and exchange input terminal wires S and T and then turn on external power switch to
deliver power once more and check the phase sequence. If phase sequence is correct, go to next
step.
(3) Initial setting procedure:
Press “ ESC” button on the LCD and return to main menu. Press ↓or↑button to option F.
