PQM/PQMII Power Quality Metering Systems Terminal Layout

RTT DESKTOP TEST SET– INSTRUCTION MANUAL
The PQM/PQMII has 3-phase current inputs with less than 0.2 VA CT Burden and 3-phase
voltage inputs with greater than 2.2 MOhm VT burden. The PQM/PQMII has four
programmable switch inputs designed for Dry contact connection only, and 4 Form-C
output relays.
All features of RTT, other than RTDs, can be applied to the PQM/PQMII. However there are
13 unused input terminal wires, a modification is required to the cable to fit the PQM/PQMII
terminals.
Modification of the Product Cable
For the wires related to contact inputs and contact outputs (8 in total), cut lugs off the and
strip the wires to make them fit the PQM/PQMII terminals.
The wires to be cut are: DOC, DO2, DO1, DIC, DI4, DI3, DI2 and DI1.
Unused Wires
For the unused wires (13 in total), it is recommended that user tape the lugs to ensure
isolation of the contacts so that no problems are caused by wires touching.
The unused wires are: R1+, R1-, R1C, R2+, R2-, R2C, R3+, R3-, R3C, DI8, DI7, DI6 and DI5.
