Information:
Mounting Locations
The load sharing module is designed to operate within a temperature range of -40 °C (-40 °F) to 75 °C (167 °F). The unit may be mounted in any position if the required ventilation is available for cooling and the unit is not in a high vibration area.Do NOT mount the control near very high temperature areas or near auxiliary electrical equipment. The control must not be mounted on the engine. The control should have space available for servicing and repair.Electrical Connections
Refer to the wiring diagram in Testing and Adjusting, "Wiring Diagrams" for all external wiring connections of a typical control installation. Be sure to follow all shielding requirements. The information that follows gives additional specific wiring instructions.Shielded Wiring
All shielded cable must be twisted pair wiring. Do NOT try to tin the braided shield. All input control wires should be shielded. See wiring drawing for shielding requirements. This prevents any effects from outside signals (EMI) that are caused by other electronic equipment near the cable. Connect one point of the shield to the system ground (or common) at the control end only. The end away from the control should be left open. Do NOT run shielded wires in the same conduit with cables that carry high current.Potential Transformer (PT) Connections
Connect the secondary leads of the potential transformer (PT) to the following terminals.
Phase A to T1
Phase B to T2
Phase C to T3The PT secondary line to line voltage must be from 90 to 240 RMS Volts. See Testing and Adjusting, "Wiring Diagrams".Current Transformer (CT) Connections
Connect the current transformer (CT) secondary leads. See Testing and Adjusting, "Wiring Diagrams". The CT rating should be sized to produce near 5 Amperes secondary current with the generator at full rated output. The CT phasing and PT phasing is critical for proper operation. See Testing And Adjusting, "Phasing - Adjust".
Never disconnect current transformers from the Generator Set Load Sensor when the engine is running. The current transformers can develop very high voltages when open circuited with the unit loaded. This can result in serious injury or death to personnel.
Note: Terminals 4 through 9 of the load sharing module are the input terminals from the current transformers.
