The Interface 5000's AC Adapter is rated for operation from 100 to 240 V AC, 47 to 63 Hz.
It should therefore be useful throughout the world.
The Interface 5000 is normally provided with an AC line cord suitable for your location. This AC line cord
connects the AC mains to the AC power adapter. If your Interface 5000 has been provided without an AC line
cord, or a cord that is not compatible with your local AC mains socket, obtain a line cord certified for use in
your country. Contact your local Gamry Representative or email to
uncertain what AC line cord to use.
Grounding in the Interface 5000
The circuitry and the metal case of the Interface 5000 are not connected to an earth ground. If they were
connected to earth ground, it would compromise the Interface 5000's ability to make measurements in
electrochemical cells that contain earth-grounded metal. A few examples of such cells include fuel cells, flow
batteries, and certain complex battery-packs.
Most electrochemical cells are isolated from earth ground, so isolation of the Interface 5000 from earth is not
required. In these cases, connection of the Interface 5000 chassis to an earth ground may lower the noise seen
in an electrochemical test. A Chassis Ground banana jack on the rear panel of the Interface 5000 easily
implements this connection. Simply run a wire from this binding post to a suitable source of earth ground. A
black 1.2-meter banana-to-banana lead is provided with the Interface 5000 to facilitate this connection.
Sources of earth ground include
• Most metal water pipes,
• The chassis of most electronic apparatus (which are generally earth-grounded), and
• The protective ground terminal of an AC mains power plug.
We recommend that you discuss grounding with an electrical or electronics professional prior to making this
earth-ground connection.
This connection of the Interface 5000 to an earth ground is not a "Protective Earth Ground" as defined in EN
61010. The Interface 5000 is safe in the absence of this connection.
This binding post is not intended for any use other than connecting the Interface 5000 to an earth ground to
improve shielding against noise. Connecting this binding post to a hazardous voltage can create a significant
safety hazard.
Warning:
earth ground. An improper connection can create a safety hazard, which could result in personal injury or
death.
Safety Considerations
Do not connect the chassis ground binding post to any voltage other than
