INSTALLATION

Mount the LSM200 Series Module in the generator set control cabinet with the other dedicated control equipment. Locate the load shar-

ing, synchronizer, and speed control devices as close together as possible to minimize inter-connection cable lengths.

All generator sets that are to be synchronized must be tested independently for their maximum capabilities. Information should be gath

-

ered for reference if operational issues arise after installation of this product.

Read this entire installation manual before starting installation of this product.

•

An overspeed shutdown device, independent of the governor system, should be used to prevent loss of engine control

which may cause personal injury or equipment damage.

• Do not rely exclusively on the governor system electric actuator to prevent overspeed. A secondary shutoff device, such

as a fuel solenoid must be used.
