Adapter Kit - QSI Electronics to OM Meter
Installation Instructions
These installation instructions
cover the adapter kit installation of
the QSI1, QSI2 and QSI3 versions
of communications electronics to
OM 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 OM meter is
disconnected.
INSTRUCTIONS
1. Remove the circular plate (or
other product) from the top
of your OM 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
2).
3. Install the O-ring received with
the kit in the O-ring gland on the
bottom of the adapter; mount
the adapter to the OM meter and
secure with (4) metric screws
provided with the kit. Tighten
screws.
4. Make sure the seal is in place on
top of the adapter prior to routing
the wiring from the meter.
5. Route the wiring from the meter
up through the adapter and
connect the wires to the QSI
PC board screw connectors,
per the wiring diagram in these
instructions.

6. To route external power and/or
electronic cables to the QSI PC
board screw connectors, 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 relief(s), 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 connectors
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.
