or, it may be installed directly to the LP-
2 option board. Either way, the I/O-2
option board is installed in a similar
manner to the LP-2 option board
described in step 6 above.
10. Depending on whether the installation is
being made to an S-base or A-base
meter, install the appropriate cable
assembly as described below. For
installation on a switchboard kV Meter,
refer to the switchboard meter
instruction book, GEH-7271.
Installation on S-base Meters
While the meter is unassembled, the S-base
communications cable assembly must be
installed. This cable assembly is installed in
S-base meters as follows:
1. With the kV™ Meter base facing you,
locate the lower of the two small
knockouts and remove it (see Figure 6:
Locating knockout for cable assembly
on S-Base meters). Enlarge the hole to
a diameter of 0.290 inches. Make sure
the resulting hole is clean.

assembly on S-Base meters
2. Locate the end of the cable assembly
with the two small black connectors.
Pass the larger of the black connectors
through the knockout hole from the back
side of the meter base. Next, pass the
smaller black connector through the
same hole and pull until the wire tie is in
the slot and up against the base. Make
sure that the cable has been brought up
on the outside of the shroud.
3. Check the headers on the kV RSX
board to make sure that the pins are not
bent or out of position. Orient the
smallest black connector such that the
indexed (filled) hole in the black
connector is lined up with the missing
pin in the 4 pin header. Plug the
connector assembly into the header on
the RSX board. Orient the larger black
connector such that the indexed (filled)
hole in the black connector is lined up
with the missing pin in the 6 pin header.
Plug the connector assembly into the
header on the RSX board.
4. Attach the plastic connector holder as
shown in Figure 7. The connector
holder snaps should extend through the
holes in the kV RSX board and snap
into place.

5. Check the 30 pin header on the meter
board to make sure that the pins are not
bent or out of position. Adjust any pins
that are out of alignment.
