INSTALLATION INSTRUCTIONS
5. Make sure the seal is in place
on top of the base prior to
reattaching (if previously
disconnected) the (2) wires to
the screw terminal of the pick-up
circuit board.
6. To route external power and/
or electronic cables to the
QSB or QSI PC board screw
connectors, prepare the cover
plate by removing the plug and
sealing washer from each port
that you intend to use. Replace
the removed plugs with a strain
relief w/O-ring. The strain relief
will accommodate cable sizes of
0.11 in. (2.8 mm) through 0.26 in.
(6.6 mm) diameter. Leave the
factory installed plugs in any
unused ports.
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
QSB or QSI PC board screw
connectors (see Figure 6, 8, 10,
or 12 depending on your module
version).
9. Mount the cover plate on the
base making sure the seal is
seated properly between them.
Replace the (6) previously
removed screws to secure the
cover plate to the base. Tighten
screws.
10. Connect power to QSB or QSI
module and meter.
NOTE: For ALL electronic modules.
1. Make sure the QSB or
QSI module and meter are
disconnected from power source.
2. Remove any attached product, if
it exists, from the top of your G2
meter. It will be replaced with the
module components.
3. Remove the (6) #8-16 x 3/4 in.
screws attaching the module
cover plate to the base and
separate. Do not damage the seal
between the two components.
The (2) wires connecting the QSB
or QSI PC board to the screw
terminal of the pick-up circuit
board are long enough to allow
separation of parts. The wires
may be disconnected from the
screw terminal if necessary. The
wires are non-polarized and may
be connected to either screw of
the screw terminal (see Figure 4).
4. Install the gasket received with
the module on the bottom of the
base. Mount the base to the G2
meter, seating the pick-up coil in
the meter recess. Secure base
with (4) screws provided with the
module. Tighten screws.
NOTE:
Use #4-40 screws for metallic
meters or #4-20 Plastite® screws for
PVDF meters.
