Power Measurement—Connecting Sensors & Configuring Channels
The ELITEpro XC can monitor AC power loads ranging from single phase, 2-wire to 3 phase-4 wire
systems and up to 600 VAC at 50 or 60Hz.
Read all warning symbols described in the Safety section AT THE BEGINNING OF THIS MANUAL.
Use the proper Current Transformers (CTs) for the load being monitored. For a complete discussion on
this, see the section Current Transformer (CT) Selection below.
CAUTION: DO NOT USE UNSHUNTED CTs. ONLY USE SHUNTED CTS FROM DENT INSTRUMENTS
WITH 333 mVAC OUTPUT. ALL DIAGRAMS IN THIS SECTION SHOW THE CT PHASING ARROW
POINTING TOWARD THE LOAD.
Always orient the arrow on the CT towards the load or as otherwise indicated on the CT. All diagrams in
this section will show the CT phasing arrow oriented towards the load.
Always connect the white neutral wire to the neutral bus bar, if available, or to the L2 or L3 phase if
metering a 3-phase, 3-wire system with no neutral.
WARNING: Use of this device in a manner for which it is not intended may impair its means of
protection. Do not exceed 600 VAC voltage inputs!
When connecting the ELITEpro XC to an AC load, follow these steps in sequence to prevent a shock
hazard.
1) If possible, de-energize the circuit to be monitored.
2) Connect the CTs to the phases being monitored.
3) Connect the voltage leads to the different phases. Use proper safety equipment (gloves,
ma
sk, and protective clothing) as required for the voltages monitored.
