22 is used for outputs 4, 5, and 6, terminal 26 is used for outputs 7, 8, and 9, 30 is used for outputs 10,
11, and 12.
Metering
Generator and Bus Voltage (rms)
Metering Range ................................ 0 to 576 Vac (direct measurement)
577 to 9,999 Vac (through VT using VT ratio setting)
VT Ratio Range ................................ 1:1 to 125:1 in primary increments of 1
Accuracy
* ......................................... ±1.0% of programmed rated voltage or ±2 Vac
Display Resolution ........................... 1 Vac
* Voltage metering indicates 0 V when generator voltage is below 2% of the full-scale rating.
Generator Current (rms)
Generator current is measured at the secondary windings of user-supplied 1 A or 5 A CTs.
Metering Range ................................ 0 to 5,000 Aac
CT Primary Range ........................... 1 to 5,000 Aac in primary increments of 1 Aac
Accuracy
* ......................................... ±1.0% of programmed rated current or ±2 Aac
Display Resolution ........................... 1 Aac
* Current metering indicates 0 A when generator current is below 2% of the full-scale rating.
Generator and Bus Frequency
Frequency is sensed through the generator and bus voltage inputs (phases A and B).
Metering Range ................................ 10 to 90 Hz
Accuracy...........................................
±0.25% or 0.05 Hz
Display Resolution ........................... 0.1 Hz
Apparent Power
Indicates total kVA and individual line kVA (4-wire, line-to-neutral or 3-wire, line-to-line).
Measurement/Calculation Methods

* kVA metering indicates 0 kVA when the generator kVA is below 2% of the full-scale rating.
† Applies when temperature is between
−40°C to +70°C (–40°F to +158°F).
