2.6 PT Setup
Set the PT according to the PM175 Installation and Operation Manual, Section 4.1 or the
PAS User’s Manual, Section 6.1.1.

. Connect the probes to the line conductors according to the power system
configuration.
2.8 Current Sensors Connection
Connect the current sensors first to the EDL175 and then to the measured circuit.
There is a common connector for all types of current sensors in each phase. NOTE:
The nominal secondary outputs of the current sensors can be 1A or up to 3V.
2.8.1 Standard Clamps The EDL175 contains a set of standard current clamps with 1A
secondary nominal current
and primary nominal current according to the order specification (120A / 200A/ 1000A /
3000A). Maximum EDL175 measured current is 200% of the nominal current. All current
clamps in the kit have built-in protection against clamp connector disconnection.
