2.3. VT , VX & CT Connections
VT Terminal Voltage Connections:
Voltage Inputs can accept up to 600Vac L:L / 347VL:G direct. A PT with a 120V secondary
is required If this rating is exceeded. Primary settings are 120-500,000, for a PT ratio of
120:120 to 500000 to 120. It is strongly recommended that the Voltage Inputs be con-
nected to the Meter Module by way of properly rated disconnect switches.
• VTV1 = Line 1 or Va
• VTV2 = Line 2 or Vb
• VTV3 = Line 3 or Vc
• VTV4 = Line 4 or Vn (neutral)
• VTVR = Metering Reference Ground
VX Optional Auxiliary Voltage Connections:
• VXV6 = Line 1’ or Va2
• VXV7 = Line 2’ or Vb2
• VXV8 = Line 3’ or Vc2
CT Terminal Connections:
Current Inputs accepts a 5-amp secondary with available Primary settings of 5-9999, for a
CT ratio of 5:5 to 9999:5. It is strongly recommended that the Current Inputs be connected
to the Meter Module by way of a shorting block.
