5. When connecting output terminals (See Fig. 9.)
• Remove the protection cover of output terminals.
• Loosen the cable clamp and push the wire ends of the load cable through the clamp and
rubber cover.
• Connect the wires to the proper terminals:
L1/L2/L3/PE, and if required N, for 3-phase load
N/L1, N/L2, N/L3 and PE for single-phase load
• Tighten the bolts securely.
• Reinstall the protecting cover in front of the output terminal board.
• Tighten the clamp to fasten the cable.
3-3 Before starting
The generators are factory-adjusted to operate at 50 Hz, i.e. 1500 r/min.
3-3-1 Checkup before start-up
1. Checking the oil level
• Check the engine oil level or contamination by the dipstick. The oil level must be near to,
but not exceed, the high mark on the dipstick. If required, refill or change the oil.
• If necessary, pour oil up to the specified level through the oil refilling port provided on the
engine.
• For oil change, loosen the oil drain plug from the generator base to drain and, thereafter, pour
oil the same as refilling. Dispose of the discharged oil in compliance with the local regulations.
• After supplying oil, run for several minutes, then stop the engine and make sure that the oil
level is between the high and low marks.
• For the oil volume, see the lubricant volume in the specification table.
2. Checking the cooling water in engine radiator
• Check that the water level is near the Full mark on the auxiliary tank. Refill if short.
• Use soft water as engine cooling water. Use anti-freeze solution where the atmospheric tem-
perature is low.
Mixing volume of anti-freeze solution = total cooling water volume×mixing anti-freeze solution
concentration. For the total cooling water volume, see the engine specification table.
For anti-freeze solution concentration at the temperature, see “Fuel coolant and lubricants”.
• For making up water, remove the radiator cap. Thereafter, securely install the cap so as to be
airtight.
