The generator can operate in either direction of rotation. The phase sequence is set for clockwise rotation as viewed when facing the coupling disc assembly (1). For clockwise rotation, the alternator terminals are marked so the sequence of terminals 1, 2 and 3 match the sequence of phases R, S and T or L1, L2, and L3. For applications that require counterclockwise direction for the generator, the phase sequence must be changed. Check the rotation direction and sequence of phases before the generator is placed into operation.
The wrong phase sequence may damage the equipment that is powered by the generator. In the case of parallel operation with other generator and/or network, the generator must have the same phase sequence.
Protection Degree
The proper performance and durability of the generator depend on the degree of protection for the generator. The generator must be installed in an appropriate environment. The generator has the protection degree IP21. IP21 means that the generator is protected against penetration of solid bodies that are larger than 12 mm (0.47 inch). IP21 also means that the generator is protected against a sprinkling of water from a vertical direction.Cooling
