IPSi2400 Series Manual

There are 8 LED indicators labelled 1 through 8. Their functions are as follows:

1. Low Input Voltage: Blinks Red when the input voltage is near the lower limit for proper

operation. Glows Red when the input voltage is too low for proper operation and will be

accompanied by the Bypass LED glowing Red and the On/Off switch will not be glowing.

Check for the reason for low voltage.

2. High Input Voltage: Blinks Red when the input voltage is near the upper limit for proper

operation. Glows Red when the input voltage is too high for proper operation and will be

accompanied by the Bypass LED glowing Red and the On/Off switch not glowing. Check

for the reason for high voltage. The inverter can be damaged if the input voltage exceeds

the maximum rating, and excess voltage damage is not covered under warranty.

3. Over Temp: Blinks Red if the internal temperature of the inverter is approaching the safe

limit. The inverter will reduce its maximum power rating to try to maintain the tempera-

ture within safe limits. The LED will glow Red if the inverter is too hot to operate and

the Bypass LED will also glow Red and the On/Off switch will stop glowing. Either the

cooling fan is defective, or there is not enough air circulation for the inverter. If the fan is

running, add extra ventilation. If the fan is NOT running the inverter must be returned for

repair.

4. Overload: Blinks Red if the load on the inverter reaches the continuous rating. Solid Red

if the load on the inverter reaches the maximum rating. Reduce the load on the inverter.

5. 50 Hz: This LED will be on Green if the inverter is set for 50 Hz operation.

6. 60 Hz: This LED will be on Green if the inverter is set for 60 Hz operation.

7. Bypass: This LED will be on Green if the inverter is in Bypass mode, or on Red if the

inverter is in an Alarm condition as described above.

8. Invert: This LED will be on Green when the inverter is in normal operation.
