Mounting: The voltage regulator can be mounted in any position without affecting its operating characteristics. The voltage regulator is convection cooled. Retain suf cient space around the regulator for heat dissipation and for making electrical connections and controls adjustments. Mount the voltage regulator in any location where shock and vibration are not excessive and the ambient temperature does not exceed its ambient operational limits. Interconnection: Connect the regulator to the generator system as instructed in this section and as shown in the connection diagram provided with the generator set. See Figure 3 for an overall outline drawing that shows the location of regulator mounting provision and parts of the voltage regulator. See Figures 4 to 11 for a typical interconnection diagrams and electrical schematics of the voltage regulator. Use 14 gauge or larger wire for connections to the voltage regulator. Single-phase 100 to 600 Vac sensing (terminals El and E3): The standard KCR 760 voltage regulator designed for single phase sensing has an internal sensing transformer (T1) as shown in Figure 4. This transformer is provided with taps on the primary winding for sensing voltages of 100 to 139, 200 to 228, 216 to 265, 375 to 458, 432 to 528, and 540 to 600 Vac. The transformer primary winding taps are identi ed with the corresponding nominal voltages, which are 120, 208, 240, 416, 480, and 600. Vac. To obtain proper operation the internal wire from voltage regulator terminal E3 must be connected onto the correct primary tap on transformer T1. Electrical wires within the regulator connect to the sensing transformer secondary winding as shown in Figure 4. Three-phase 100 to 600 Vac sensing (terminals El, E2, and E3): When the regulator is designed for three-phase sensing, it includes two sensing transformers (T1 and T3) as shown in Figure 5. Except when otherwise speci ed in the purchase order, the regulator sensing transformers will both include multi-tap primary winding for use with the sensing voltages described in the single phase 100 to 600 Vac sensing procedure. To properly operate, connect the internal wire from voltage regulator terminal E3 to the correct primary winding tap on transformer T1, and connect the internal wire from voltage regulator terminal E2 to the corresponding primary winding tap on transformer T3. Connect electrical wires within the regulator to the sensing transformers secondary winding as shown in Figure 5.
