Installation
CENTRON® OpenWay™ Meter Technical Reference Guide 13
Selecting a Site
The meter is designed and manufactured to be installed in an outdoor environment, at
operating temperature ranges between -40° C and +85° C (-40° F to +185° F). Operation in
moderate temperatures increases reliability and product life.
Installing the Meter into Service
Install the meter base using standard meter installation practices.
The current and potential terminals extend as blades, or bayonets, from the back of the
meter. The meter is plugged into the socket so that the bayonets engage the main socket
jaws that connect to the service lines. Clamping pressure on the bayonets is provided by the
heavy spring pressure of the socket jaws. In some heavy-duty sockets, jaw clamping
pressure is provided by a handle or wrench.
Retrofitting with Personality Modules
CENTRON OpenWay meters can be upgraded to increase functionality by changing the
Personality Modules.
Do not power ON the meter without the inner cover in place. Power
the meter OFF before removing the inner cover. Personality modules
are sensitive to ESD damage. Take appropriate grounding measures
before retrofitting!
To change or add a Personality Module:
1 De-energize the meter.
2 Remove the outer cover.
3 Remove plastic inner cover by holding the meter with both hands and applying equal
pressure on either side of the three and nine-o’clock positions. The inner cover is held in
place by four plastic tabs on the meter base.
4 Remove the black board-to-board connector (
M in the figure below) between the
circuit board and the metrology board by pulling it by its middle while moving it side-
to-side. To maintain the integrity of the connector, only remove it when you are
upgrading the meter.
5 Remove the register module, one side at a time, by pulling gently outward on the meter
frame snaps (
N in the figure above) while lifting the module up.
6 Snap the new module into the meter frame by aligning the notches at bottom of the
circuit board with the lower two snaps.
