5) Three-phase generating set
Balance three phases during the operation. Stop the engine for check if the
tolerances exceed 20%. Be sure to keep the tolerance among three phases less
than 20%.
The load for each phase must below the rated load as well as the current must
less than rated current.
A, B, C, D (or U, V, W, N) phase arrangement should be from left to right, or
clockwise.
Concerning starting the three phases asynchronous motors, first start the
heavy-duty motors, and then start the light-duty motors.
If overloading of the circuit trips the AC circuit protector, reduce the electrical
load on the circuit, and wait a few minutes before resuming operation.
CAUTION
6. STOP PROCEDURE
1. Set the main switch to OFF.
2. Turn the breaker to the OFF.
3. Turn the start switch to the STOP position after running for 1-3 minutes with
zero load, then the generator stopped.
First disconnect the unit and load, then stop the generator.
