Adapter Kit - QSI Electronics to G-Series Meter
Installation Instructions
INSTRUCTIONS
1. Remove any attached products
from the 1” male NPT tting on
top of your G-Series meter. It will
be replaced with the adapter kit
components.
2. Remove the (6) #8-16 x 3/4
screws attaching the kit cover
plate to the adapter and separate.
Do not damage the seal between
the two components (see Figure 1).
3. Screw the kit elbow adapter onto
the 1” NPT tting on top of your
G-Series meter, aligning the face
of the adapter (still attached to
the elbow) in desired direction.
4. Make sure the seal is in place on
the face of the adapter prior to
routing the wiring from the meter.
5. Route the (2) wires from the meter
sensor through the elbow adapter
and out the face of the adapter.
Snip ends to remove stripped
wire. Connect either of the meter
sensor wires to either wire from
the QSI PC board using the
enclosed butt-splice connectors
(see Figure 1). Crimp connector
to splice wires and release
insulation gel. Repeat with the
remaining sensor and PC board
wire. See wiring diagram in these
instructions.
6. To route external power and/or
electronic cables to the QSI PC
board screw terminals, prepare
the cover plate by removing the
mushroom plug from each strain
relief you intend to use. The strain
relief will accommodate cable
sizes of 0.11” (0.28 cm) through
0.26” (0.66 cm) diameter.
7. Make sure the power is
disconnected from external
cables before beginning this
step. Route external cables
through the strain reliefs, and then
tighten the dome nut securely
around the cable to provide an
environmental seal.
8. Connect cable wires to the QSI
PC board screw terminals per
the wiring diagram in these
instructions.
9. Mount the cover plate on the
adapter making sure the seal
is seated properly between
them. Replace the (6) previously
removed screws to secure
the cover plate to the adapter.
Tighten screws.
These installation instructions cover
the adapter kit installation of the QSI1,
QSI2 and QSI3 versions of communi-
cations electronics to G-Series Meters.
The instructions are the same for QSI
versions with or without a display.
Check the contents of your kit using
the list below as a reference. Make
sure the power to your G-Series
meter is disconnected.

*NOTE: It is not recommended to
connect isolated ground connections
together or to board common.
**NOTE: Polarity of voltage for AC/
DC is not important. However an
earth ground isolated power supply is
required to prevent earth ground loop
currents and ground fault conditions.
***NOTE: This output may require an
external pull up resistor if interfacing
equipment does not include one.
