Space Heater Connection Diagram
A Cat generator can operate in high humidity conditions without problems. The humidity can be as high as 100% no condensing humidity. However, problems can occur when the generator is idle and the surrounding air is warmer than the generator. Moisture can form on the windings. Moisture will result in poor performance or even damage to the windings. Whenever the generator is not active, the optional space heaters should be operated.An external source is required to operate the space heaters. Both of the sources must be a single phase. This source can be either 115 VAC or 230 VAC. When the external source is 50 Hz, 200 VAC must be used. Refer to Illustration 1.See your Cat dealer for information on checking your Cat generator.
