LED N0.	NORMAL	INTERPRETATION – ACTION
	STATE
1.	ON	If this green led is OFF, it signifies a problem with the Bypass input a.c.
		Check the following –
		1.	Bypass input power switch Q2 is closed.
		2.	Input Supply voltage is within 10% of nominal
		3.	Power supply fuses are OK – on the a.c. Power supply board will extinguish if either fuse is
			ruptured.
		If the above checks prove unsatisfactory then seek qualified assistance.
2.	ON	If this led is OFF, a problem exists in the Input power supply or in a part of the rectifier. An alarm message
		is visible at the display.
		Check the following –
		1.	The rectifier input isolator (Q1) is closed.
		2.	The input voltage is within the limits of normal operation.
		3.	The phase sequence of the mains input is correct.
		4.	Verify that condition leading to an emergency stop has not happened, in which case a Reset
			must be carried out.
		If these checks do not give a positive result, request qualified assistance.
3.	OFF	If this yellow led is ON it signifies that the battery is not available. This could be due to the battery circuit
		breaker being open or that the d.c. busbar voltage is below the figures stated in the item(2) specified
		above.
		The battery circuit breaker will open automatically if the d.c. voltage falls below these levels.
		Check the following –
		1.	Check that the conditions for led(2) are satisfied.
		2.	DC busbar voltage – if not above 320V, then carry out checks as for led(2) – mains rectifier
			failure above. If d.c. busbar voltage is above 320V but you are unable to close the battery
			circuit breaker then seek qualified assistance.
		3.	Battery circuit breaker is closed.
		If the above checks prove unsatisfactory, then seek qualified assistance.

4.

ON

If this green led is OFF, it signifies that the inverter is not producing its correct output voltage.
