These reactors are designed to be floor-mounted or wall-mounted. Large open-style devices should
be panel mounted by incorporating a bracket that would act as a shelf to support the reactor and/or
enclosure. When installing an open style device in an existing control cabinet, drive cabinet, motor
control center, or other large enclosure, the reactor should be mounted in the lower half of the cabinet
to prevent hot spots or pockets of heat. Locating the reactor in the lower half of the cabinet typically
allows better thermal dissipation and heat convection. Reactors with ducts should be mounted
vertically for proper cooling.
NOTE:
If the PQconnect PCB board is included in your kit please read through mounting and wiring
practices found in section 5.0.
Line Reactor Wiring
In the higher performance HGP design, tapped line reactor wiring is more critical than standard line
reactor designs. Before tapped line reactors, it did not matter if you connected the A1, B1, C1 to the
line side or the drive side, however, on the HGP, the terminals cannot be swapped. Incorrect wiring of
the line reactor will result in poor harmonic mitigation and could damage the reactor. Consult the
reactor drawing for your line reactor to verify proper filter wiring. All line reactor drawings are available
on the parts web page:

The incoming line must be wired to the winding start noted as A1, B1, and C1 in the reactor
drawing. The tuned circuit is typically connected to the winding tap noted as AT, BT, and CT in
the reactor drawing, or it may be connected to the winding end noted as A2, B2, and C2 in the
reactor drawing.

In small line reactors with nine position terminal blocks, the terminal block is wired A1, AT,
A2, B1, BT, B2, C1, CT, and C2 from left to right.
