1-3. Inspecting the Unit
Mechanical Checklist
▌Check the key, encoder switch, and power switch for damages.
▌Check the panel surfaces for dents or scratches.
▌Check the rear output terminals for damages.
▌Check the unit's body for dents or scratches.
▌Check the LCD for cracks and scratches.
Electrical Checklist
▌Check for an alarm sound after connecting power to the unit.
An alarm sounding at this step is probably indication of an error during self-testing.
You can read the error code by pressing the error key.
For more details regarding errors, refer to “7.Error Messages.”
For the self-testing, refer to 『1-6. Check after Power On』
▌The LCD displays the company logo and model name during the initial self-testing phase.
▌If the "**OUTPUT OFF**” message is displayed without any problems, refer to the specifications
while checking the unit.

Technologies regarding questions or get technical advice by referring to the Q&A in the
company homepage or calling.

1-5. Checking Before Connecting Power
Checking the AC Input Cable
Checking the Input Power
▌This product is designed for 3Phase 342Vac ~ 440Vac / 50-60Hz.
▌To protect the unit from severe damage caused by overloading,
it has built-in fast fuses. If the unit does not turn on even after turning on power switch,
you can request A/S from a nearby service center or the head office.
▌The AC input cable provided in the package is a 4-Wire (R,S,T,G) cable.
For custom cables, use cable appropriate for power supply's capacity.
Likewise, connect power line's earth and the unit’s GND before use.

1-6. Checking After Connecting Power
Procedure Checklist
▌The logo of the manufacturer, “ODA Technologies,” is displayed.
▌The model name, “MX-Series,” is displayed.
▌The frontal ERR, LMT, RMT, and LOCK lamps are all turned on and off, starting from the left.
Does not apply for CV and CC annunciators.
▌During the display, the unit is initialized by receiving various data
from the internal non-volatile memory.
▌The unit starts self-testing as well. The criteria for self-testing are shown below.
Connection status with the front panel
Remote Interface Test Remote interface board for PC connection
Memory Data Verification Test
Unit profile and settings data
ADC H/W Error Test
ADC control condition status
Unregulated State Test Output voltage floating status
ADC/DAC Calibration Verification Test ADC and DAC calibration data status
If an error occurs, the alarm rings, and the error code is saved to the volatile memory.
You can read the error code by pressing the error key.
For more details regarding errors, refer to “7.Error Messages”
Default Setting Values (If the Last State Mode is Disabled)
▌OVP: OVP is set for the maximum value,
▌Remote Interface: Set to maintain the previous settings
OVP is set to ON
▌OCP: OCP is set for the maximum value,
▌State after self-testing: "**OUTPUT OFF**"
OCP is set to ON
▌UVL: 0V
▌Cursor location: Default voltage select
▌OVL: Maximum value
Voltage: 1V
▌UCL: 0A Current: 100mA if current is below 5A
▌OCL: Maximum value In case of under 50A: 1A
▌Output Voltage: 0V In case of under 100A: 10A
▌Output Current: Maximum value ▌KEY LOCK: OFF
The default remote interface is RS232C with baud-rate setting of 9,600bps.
When the unit’s power switch is turned on, the unit starts operating with the initial settings and
self-testing. In addition, the unit maintains the remote interface settings while setting the
output voltage for 0V and the output current for the maximum value (This is the initial factory
settings when the last state is disabled). The OVP & OCP are set to the maximum output value
of the unit’s capacity, and monitoring begins (initial factory settings).
Note1
Note2
Front Panel Test
The last state is disabled at the time of shipping from the factory. To reset various settings
such as voltage/current to the state before you turn off the unit, you can change the settings
in Factory Mode.

1-7. Installation
Cooling
▌This unit can operate without performance loss within the temperature range of 0℃ ~ 50℃,
<Figure 1-4 Bottom view>
Bench Operation
▌There must be enough space for airflow in the front and rear of this unit.
The bottom has no air vent, so you can operate the unit without taking this into consideration.
so this must be taken into consideration when installing the unit.
If the temperature is between 50℃ ~ 55℃, decrease the output current to
0~70%.
When installing the unit on a rack, take care about the airflow. Using a rack
bracket will not impede the airflow.
