Complete the Wiring Connections
The following connections must be completed to install the ELITEpro XC. ALL WORK SHOULD BE
PERFORMED BY A QUALIFIED ELECTRICIAN USING PROPER SAFETY EQUIPMENT.
CAUTION: The ELITEpro XC should only be wired by qualified personnel. Hazardous voltages exist.
ATTENTION: LE ELITEpro XC ne doit être branché QUE par un personnel qualifié. TENSIONS
DANGEREUSES sont présentEs.
CT CONNECTIONS
NOTE: Use only inherently safe 333mV output CTs supplied by DENT. Never use current output CTs. The
UL listing covers the use of the following DENT Instruments CTs that are UL Recognized and have been
evaluated to IEC 61010-1:
C
T
-H
SC
-02
0-
X
(20A Mini), CT
-H
SC
-05
0-
X
(50A Mini), CT
-H
MC
-0
100-
X
(100A Midi), and the CT
-H
MC
-0
200-
X (200A Midi). The use of any other CT will invalidate the UL Listing of the ELITEpro XC.
1) C
onnect the CTs to the channel(s) on the ELITEpro XC labeled CH 1, CH 2, CH 3 and CH 4. The CT
leads need to be connected to the terminal block using a small screwdriver. For RōCoils, also
connect the shield (bare) wires to the right-most ground terminal marked “S” (shield).
2) Place the CTs on the phase wires of the load to be monitored and corresponding to the phase of the
voltage loads. The CTs must be placed as follows for each channel:
Left connector pin is the positive or high-side wire
Right pin is the negative or low-side
When using DENT Instruments current transformers, connect them as follows:
Split-core CTs (removable leg)—the white CT wire is (+) and the black wire is (-).
Clamp-on CTs (clothes-pin type)—the red wire is positive (+) and the black wire is negative (-).
RōCoil CTs (flexible, Rogowski-style)—the white CT wire is (+) and the brown wire is (-).
If you are using RōCoil CTs, be sure to connect the bare wire to the “S” (shield) screw terminal. This
reduces interference and improves the accuracy of the CT
