Generac MCG1000MT2 Generator Set

⚠ Contact Generac Mobile Products Technical Service to verify the units to be used in parallel are appropriate for the planned load.

Tools: Link cable, 120 ohm resistor plugs

1. Verify each unit operates properly and set up auto (remote) starting on each unit.
2. Remove receptacle covers from the CAN receptacles.
3. Using the provided link cable, connect a CAN receptacle on the first unit to a CAN receptacle on the next unit.
4. Insert the provided 120 ohm resistor plug into the unused CAN receptacles on both units.
5. To parallel more than two units, chain link cables to the next unit; insert 120 ohm resistor plugs into unused CAN receptacles on first and last units.

⚠ Hot engine oil and parts may cause burns. Wear gloves when draining oil or changing the oil filters.

⚠ Do not use a filter wrench to install the oil filter and bypass oil filter.

⚠ Dispose of waste oil in accordance with local regulations.

Tools: Filter wrench, Drain hose, Approved container, Clean cloth

1. Ensure the oil drain valve is closed and remove the drain plug from the right side of the skid frame.
2. Attach a drain hose to the bung and route the hose into an approved container.
3. Ensure the oil level controller valve is open; open the drain valve at the engine oil pan.
4. Allow the oil to drain completely into the container.
5. Clean around the oil filters.
6. Using a filter wrench, remove the oil filters, one at a time.
7. Discard the filters and gaskets.
8. Thoroughly wipe off oil on the oil filter mounting surface with a cloth.
9. Lubricate the new gaskets with a thin film of clean engine oil.
10. Install the new oil filters, turning 3/4 to full turn after initial gasket contact.
11. Close the engine oil drain valve and reinstall the plug at the skid frame drain port.
12. Remove the cap from the oil fill port and add fresh oil.
13. Check that the level is between the Full and Add marks on the dipstick.
14. After running the unit, ensure the oil level is at the halfway mark or above in the oil level controller sight glass.

⚠ DO NOT start the unit if oil is not visible in the oil level controller sight gauge or is below the add mark on the dipstick.

⚠ DO NOT OVERFILL the crankcase.

Tools: Clean lint free cloth

1. Locate the engine oil dipstick.
2. Most accurate readings when engine is cold; if running, wait at least 10 minutes.
3. Remove the dipstick and wipe dry with a clean, lint free cloth.
4. Slowly insert the clean dipstick into the tube; confirm it is fully seated.
5. After 10 seconds, remove the dipstick; the lower of the two readings is correct.
6. Add oil if necessary; run the engine one minute, wait 10 minutes, then recheck.

⚠ All valves must be open during operation. Check prior to starting the unit.

Tools: Container

1. Place a container under the drain cocks of the water separators.
2. Open the drain cocks and drain the water.
3. Close all the drain cocks.

⚠ The stairs are very heavy. Serious injury can result if not supported properly.

1. Lowering: release the stairs from the side guides by grasping both cables and pulling toward you.
2. After lowering, pull out the bottom tab on the side rail.
3. Push down on the tab to lower the stair foot to the desired height; repeat for other side.
4. Raising: push the lower tab in.
5. Push down on the upper tab until the foot is fully retracted; repeat for other side.
6. Lift the stairs up and let the side brackets settle slowly into the side guards of the door.

⚠ NEVER perform routine service unless all electrical components are shut off.

1. Ensure power to the load can be interrupted and warn equipment users.
2. Push the Gen-Set button on the controller to open the Main Circuit Breaker (MCB).
3. Allow the unit to cool down (running at no-load) for approximately five minutes.
4. Push the Stop/Reset (O) button on the controller.
5. Turn the battery disconnect switch to the OFF position.
6. Perform the necessary maintenance checks or tasks.
7. Turn the battery disconnect to the ON position.
8. Push the Start (I) button on the controller.
9. Verify all engine/generator parameters are correct, then push the Gen-Set button to close the MCB.
10. Make a last visual inspection of the unit.

⚠ Follow all safety warnings on isolating the generator with a transfer switch if used as a standby power supply.

Tools: Jumper wire minimum 16 gauge

1. Perform a manual start of the unit at least once to verify that the engine is operating correctly.
2. Connect the remote start wires to terminals #12 and #34 on TB4.
3. Remove the jumper wire from the terminal block and the engine will stop; reconnect remote start switch wires.
4. Confirm the unit is in Auto Mode; the LCD window should show "Auto Mode" at the top of the screen.
5. The unit is now ready for remote starting.

⚠ NEVER start the unit under load. The circuit breaker must be off when starting the unit.

1. Turn the battery disconnect switch to the ON position.
2. Push the Manual Mode button on the controller.
3. Push the Start (I) button.
4. Allow the engine to warm sufficiently (about 15 minutes) before adding a load.
5. Push the Gen-Set button on the controller to close the main circuit breaker.

⚠ Check with personnel using power before shutting down.

1. Open the Main Circuit Breaker (MCB) by pushing the Gen-Set button on the controller.
2. Allow the unit to cool down (running at no-load) for approximately five minutes.
3. Push the Stop (O) button on the controller.
4. Turn the battery disconnect switch to the OFF position.
