4.6 System Startup
The DC Converter contains the controls to start the MT-30. To start the system:
1.
Confirm the EMERGENCY OFF button is not actuated (depressed) on the AC
Inverter front panel. To deactivate, rotate the switch counterclockwise.
2.
Place the MAIN POWER button switch on the AC Inverter front panel in the
ON
position (green light is on). There will be a pre-charge delay of approximately ten
seconds before the AC contactor closes. During this time, some front panel lights
will come on. Once the contactor has closed, the cooling system pumps and fans
will come on. After the inverter section is functional, the DC converter will
perform a front panel lamp test and the system will be functional.
3.
Confirm the following front panel indicators for proper operation:
•
READY
(green) is lit
•
No fault indicators (red) are lit
If either of these conditions are not true then the unit is not functioning properly
and the MAIN POWER switch should be returned to the
OFF
position (green
light is off). Make note of the name and frequency of any flashing LEDs.
Reference Table 5.1 to determine the fault indicated.
4.7 Connecting the Load and selecting the Configuration
The next step is connecting the load. First, be sure that the load connectors are properly
assembled with the load cables attached to the load. See
DC Input/Output Connectors
in
Appendix II for important information about assembling and using the load connectors.
Use the rubber safety cap for each connector at all times until you are ready to insert the
connector into the DC Output receptacle.
WARNING:
Failure to use the rubber safety cap may result in users being exposed to
dangerous high voltage. If the load cable is connected to an active load that can generate
high voltage, such as a battery, this voltage will be present on the brass conductor fitting of
the connector. Safety caps should be kept in place at all times when dealing with such loads.
Next insert the load connectors into the appropriate DC Output receptacles. Refer to
Section 4.1.1
Choosing a Load Configuration
above to determine which load
connections you want to use. The MT-30 powers on into independent mode by default.
To switch to parallel mode, depress the “parallel” button after connecting the load.
