5.0 PQconnect Option
Product Description
The PQconnect is an integrated controls option for TCI’s industry sine wave filter used for filtering
the output of VFDs. In the sine wave filter, the PQconnect provides unit status detection, metering,
waveforms and power quality data. The PQconnect data is made available via basic Modbus RTU
over RS485 serial connection. The PQconnect is UL Recognized and intended for commercial and
industrial applications.
Installation
Installation Checklist
The following are the key points to be followed for a successful installation of the PQconnect boar
Make sure that the installation location will not be exposed to direct sunlight, corrosive or
combustible airborne contaminants, excessive dirt or liquids.
Select a mounting area that will allow adequate cooling air and maintenance access.
Make sure that all wiring conforms to the requirements of the National Electrical Code
(NEC) and/or other applicable electrical codes.
Connect the MFC filter grounding lug to the system ground of the premises wiring system.
Use a properly sized grounding conductor.
Connect MFC output terminals A2, B2, and C2 terminals of the KTRMG sine wave reactor
to the load.
Connect three-phase power from the tuning reactor to the input terminals of the PQconnect
board, J1, and J2 as shown in Figure 12 and described in Table 7
VFD faults and component damage may result if capacitor circuit is attached directly to
VFD three-phase output.
Connect 120VAC Power (customer supplied) to the input power supply header J12 on the
PCB
Connect RS 485 to USB serial converter to the Modbus RTU header J5.
Use PQvision software from TCI website to calibrate PQconnect PCB.
Ensure all component connections are torqued before energizing filter.
NOTE: PQvision software is required to calibrate the PQconnect PCB
Mounting
Selecting a Suitable Location
When mounting the PQconnect board, provide an adequately ventilated location to prevent
overheating. Refer to the applicable kit drawings for PCB dimensions. The maximum temperature
of the air around the MFC filter components should not exceed 50°C (122°F). Consult the watts
loss columns above in Filter Wire Sizing for Watts Loss when planning enclosure ventilation.
When selecting a mounting location for the PQconnect PCB, plan for the routing of the power
wiring. Figure 12Error! Reference source not found. Shows a representative schematic of
power wiring. Note that there are direct connections from the tuning reactor to the PQconnect PCB.
