Chapter 2 Installation
Voltage Inputs
There are 3 AC Y-connected voltage inputs of 480V (phase-to-phase) and neutral, via Main Terminal
Block.
Copper wiring 2.5 – 6 mm2 (10 AWG) should be used.
The
EM720
Power Supply Inputs are the same as the Voltages Inputs
Current Inputs
There are 4 current inputs up to 50A, connected to external CT’s via Main Terminal Block.
Copper wiring 2.5 – 6 mm2 (10 AWG) should be used.
Signal Ground Input
For Transient measurements, connect Signal Ground (SG) Input to Ground via Main Terminal Block, if
voltage neutral is isolated.
Copper wiring 2.5 – 6 mm2 (10 AWG) should be used.
If voltage neutral is grounded, the Signal Ground Input should be connected to Voltage neutral Input
