| ACINV Series 1RU Rack Mount Inverters
2.8.1
Controls and indicators:
The ON/OFF switch turns the control circuit in the power inverter on and off.
2.8.2
Output Voltage Indication
When the VDC LED is lit the display shows the Output Voltage
When the unit is first switched on the VAC LED is lit and the Output Voltage is displayed as described
above.
Selection of the following parameters is achieved by pressing the Function Selector button to the right of
the display sequentially.
2.8.3
Output Current Indicator
When the AMP LED is lit the display shows the Output Current
2.8.4
Output Watts Indicator
When the WATTS LED is lit the display shows the Output Power in Watts
2.8.5
Input DC Voltage Indicator
When the VDC LED is lit the display shows the DC Input Voltage
2.8.6
Temperature Indicator
When the TEMP LED is lit the display shows the internal Operating Temperature
2.8.7
Output Frequency AC Indicator

These inverters are designed to operate from the following input voltage ranges:
42.0 to 62.0VDC
High and low DC input voltage conditions are handled per the following table and described in

When OVP is indicated on the display the unit has shut itself down due to the input voltage exceeding the
limits shown above.

2.8.9
Under voltage protection indicator: (UVP)
When UVP is indicated on the display the unit has shut itself down due to the input voltage falling below the
limits shown above.
2.8.10 Over temp protection indicator: (OTP)
When OTP is indicated on the display the unit has shut itself down because it has become overheated.
The unit may overheat because it has been operated at power levels above its rating, or because it has
been installed in a location which does not allow it to dissipate heat properly. The unit will automatically
restart once it has cooled off.
2.8.11 Overload protection indicator: (OLP)
When OLP is indicated on the display one of two conditions has occurred as follows:
a) For an overload condition approximately 110-120% of the WATTS rating of the unit and lasting up to
around 1 minute, an audible alarm will sound and the unit will continue to deliver power directly to the load.
If the overload condition continues the unit shuts itself down.
b) For a larger overload condition the unit shuts itself down immediately.
In both cases it is necessary to restart the unit once the overload has been removed.
In all of the above cases, if an AC utility supply is connected and the AC input breaker switched ON the load will be
automatically be transferred to the utility supply.
2.9 Cooling Fan Operation
The cooling fan management system monitors both the output power and internal temperature of the unit.
The fans will not normally run if the output power is less than 300W, unless the internal temperature exceeds recommended
norms.
In the event that the ventilation openings are obstructed the unit will enter over temperature protection mode (OTP) and
the cooling fan will continue to operate in order to reduce the internal temperature to a safe operating level. Once this
has been achieved the unit will turn on automatically.
3. Maintenance
ACINV Series inverters require only minimal maintenance for reliable operation.
The exterior of the unit should be cleaned down periodically with a dry cloth to prevent accumulation of dust and dirt,
paying particular attention to the ventilation openings.
Also, the DC input terminal connections should be checked to ensure that they are sufficiently tight.
4. Troubleshooting Guide
ACINV Series inverters are designed to comply with all relevant EMI Regulations so long as they have been correctly
installed. If incorrectly installed interference with other electronic equipment in close proximity may occur.

WARNING!
Do not open or disassemble the inverter. Attempting to service
the unit yourself may result in a risk of electrical shock or fire.
Also, the warranty will be void in the event that any seals have
been broken or tampered with.
