Refer to the following notes when you are using the Illustration 1.Note 1: With a balanced three-phase load and unity power factor the current transformers should be wired in the correct potential leg. The current transformers must be phased at the controls as follows.
Phase A: Potential terminal 1, with respect to neutral, in phase with CT terminals 4 to 5
Phase B: Potential terminal 2, with respect to neutral, in phase with CT terminals 6 to 7
Phase C: Potential terminal 3, with respect to neutral, in phase with CT terminals 8 to 9Note 2: Power source current transformers should be sized to produce approximately 5 Amp secondary current with maximum generator current. CT burden is essentially 0 VA.Note 3: Contacts close when breaker to main bus closes.Note 4:
The internal ballast resistors must be connected across AC power source to current transformers when the engine is running to prevent high voltage from developing on leads to these terminals. This high voltage can result in serious injury or death to personnel.
Note 5: Place the jumper between T15 and T16 and between T17 to T18 when potential input at terminals T1 through T3 is 95 to 130 VAC phase to phase (50 to 400 Hz).Note 6: Place the jumper between T16 and T17 when potential input at terminals T1 through T3 is 190 to 260 VAC phase to phase (50 to 400 Hz).Note 7: Potential transformer burden is 5 VA per phase with 230 VAC input and 2.5 VA per phase with 115 VAC input.Note 8: Control
