When the common or star point of a 3 wire Wye system is
grounded, the 3300 ACM may be connected directly without
the use of PT’s (provided the voltages are within the input
range of the unit).
NOTES: 1. VOLTS MODE = 4 WIRE WYE. 2. Note the polarity of each CT. 3. The line transformer neutral must be
equipotential with the SWITCHGEAR CHASSIS GROUND for this meter configuration to operate properly.
