Chapter 1: Safety Considerations - Inspection
1 - 1
Chapter 1: Safety Considerations
Your VistaShield Stir/Purge has been supplied in a safe condition. This chapter of the Operator’s Manual
contains some information and warnings that you must follow to insure continued safe operation.
Inspection
When you receive your VistaShield Faraday Cage Stir/Purge, inspect it for evidence of shipping damage. If any
damage is noted, please notify Gamry Instruments Inc. and the shipping carrier immediately. Save the shipping
container for possible inspection by the carrier. The VistaShield itself has a conductive coating on the glass pane
in the door. If the glass is cracked, the conductivity could be broken, compromising the VistaShield’s ability to
function as a Faraday cage.
Product safety
The Stir/Purge option for the VistaShield Faraday Cage has been designed, tested and certified to meet the
requirements of IEC 1010, Safety requirements for electrical equipment for measurement, control, and
laboratory use. As defined in this standard, it is a Category III apparatus, designed for connection to low voltage
circuits.
The “AC Adapter” supplied with the Stir/Purge option is certified under EN 60950. The AC Adapter converts
the AC mains voltage to 12 V DC, which is used to power the Stir/Purge.
Always use the AC adapter supplied with your VistaShield Stir/Purge to supply DC power to the instrument.
AC mains connection to the power supply
The VistaShield Stir/Purge does not connect directly to an AC mains supply. Instead, the mains is connected to
the desktop AC-adapter, which outputs 12 V DC, which in turn powers the Stir/Purge.
The Stir-Purge’s AC Adapter is rated for operation from 100 to 240 volts AC,
47 to 63 Hz. It should therefore be useful throughout the world.
Warning! The door of the VistaShield contains a large pane of glass with a
conductive coating on the outside surface. Chips on the corners, while not affecting
performance, can have extremely sharp edges that represent a significant safety hazard.
Injuries from broken glass can be quite severe.
Caution: Use of a DC power source other than the AC-adapter model provided
with your Stir-Purge may void the performance and/or safety characteristics of the device.

Chapter 1: Safety Considerations - Grounding in the VistaShield and Stir/Purge
1 - 2
The VistaShield Stir/Purge 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 VistaShield 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 e-mail to [email protected] if you are
uncertain what AC line cord to use.
Grounding in the VistaShield and Stir/Purge
The circuitry and the metal case of the Stir/Purge are not connected to an earth ground. The Stir/Purge chassis is
normally in electronic contact with the VistaShield Faraday Cage above. Grounding is best accomplished by
connecting the ground lead of the potentiostat to the internal ground lug of the VistaShield Faraday Cage.
Proper grounding is required for the Faraday cage to function.
Most electrochemical cells are isolated from earth ground, in which cases isolation of the VistaShield from earth
is not required. Connection of the VistaShield to an earth ground (when allowed) may lower the noise seen in
an electrochemical test.
This connection of the VistaShield to an earth ground is not a “Protective Earth Ground” as defined in IEC
1010. The VistaShield Stir/Purge is safe in the absence of this connection, since it does not contain any
hazardous voltages.
The Stir/Purge can also be used without a VistaShield in a stand-alone configuration. Stand-alone operation is
also safe with regard to electrical shock hazards. In the unlikely event that you need to ground a stand-alone
Stir/Purge, you can connect a ground wire to one of the top cover mounting screws or to one of the metal nuts
holding a rear panel gas fitting in place.
Temperature and ventilation
Your VistaShield Stir/Purge was designed for indoor use at ambient temperatures between 0C and 45C. You
may need to ventilate or even cool the Stir/Purge with forced air if the temperature rises excessively.
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.
Warning! Do not connect the VistaShield Faraday Cage’s ground binding post
to any voltage other than a potentiostat’s floating or earth ground. An improper connection
can create a safety hazard, which could result in personal injury or death.
