Chapter 5: Cell Connections
Cell Cable Overview
The Cell Connectors are two 15-pin D-connectors on the front of the Interface 5000.
Figure 5-1
Front Panel of the Interface 5000
The left (female) connector is labeled Current Connector. It carries the cell current between the Counter
electrode wire and the Working electrode wire.
The right (male) connector is labeled Sense Connector. It contains only high-impedance inputs used to sense
potentials in the cell.
Gamry’s Interface 5000 standard cell cables always come in pairs. Each cable has a D-connector on one end,
and a number of leads to connect to electrodes in an electrochemical cell. The D-connector end of the cable is
connected to the appropriate D-Connector on the front of the Reference 5000. The male and female cables
cannot be interchanged.
Every Interface 5000 is shipped with a pair of standard shielded cell cables. The Gamry part number for a set of
these two cables is cell cables is 985-00157. They are both 60 cm complex cables, with D-connectors on one
end, and color-coded banana plugs and pin sockets on the other end.
In some cases, your system may also include special-purpose cell cables. The special-purpose cell cables
include instructions describing their use.
Always screw both cell cables into place, because cables can fall off the unit if not properly attached. This can
be disastrous if detachment occurs during an experiment.
Ancillary Apparatus
Do not use the Interface 5000 with ancillary apparatus connected directly to any of the cell leads. Examples of
ancillary apparatus include DVMs, oscilloscopes, chart-recorders, and data-loggers. Ammeters and voltmeters,
regardless of their specifications, almost always create problems when connected to the Interface 5000 cell
leads. Instead, connect ancillary measurement devices to the Monitor connector on the front panel of the
Interface 5000.
Fuses in the Cell Cable
The Interface 5000 can be damaged if currents much larger than 6 A flow into or out of the Counter electrode
or Working electrode leads. Improper connection to a battery, fuel cell, or supercapacitor can cause this type of
damaging current to flow. All Interface 5000 Counter/Working cell cables contain fuses in the cable that protect
the instrument if it is misconnected. A later section of this manual discusses the fuses and their replacement.
