DCX3000 3.0kW, 36/48VDC Portable Generator Quick Guide
The following instructions are intended to supplement the DCX3000 Operator’s Manual. Read and adhere to all safety
instructions listed in the Operator’s Manual (Alpha P/N 041-028-B0) and this document. If you have any questions
regarding safe operation of the generator, consult the Operator’s Manual or contact Alpha Technical Support.
WARNING!
Do not make or break any connections between the power supply battery pack and generator while the
generator is running. Turn the generator off before disconnecting any cables or equipment.
CAUTION!
Always check the engine oil level prior to operating the generator. Failure to do so could lead to
irreparable damage to the engine.
CAUTION!
Only use 86 octane fuel or higher and no more than 10% Ethanol or 5% Methanol by volume.
1.0 Connecting Generator
1. Open the maintenance cover (see Figure 1-1).
2. Using the DC voltage selector switch, select either 36V or 48V (see Figure 1-1).
3. Close the maintenance cover.
4. Connect the power cord of the UPS to the DC output coupler, ensuring there is no gap (see Figure 1-2).
