Chapter 1: Safety Considerations - Inspection
1 - 1
Chapter 1: Safety Considerations
Your Faraday Shield 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 Faraday Shield, 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.
Grounding in the Faraday Shield
The metal case of the Faraday Shield is not connected to an earth ground. Grounding is best accomplished by
connecting the ground lead of the potentiostat to the internal ground lug of the Faraday Shield. Proper grounding
is required for the Faraday cage to function.
Most electrochemical cells are isolated from earth ground, in which cases isolation of the Faraday Shield from
earth is not required. Connection of the Faraday Shield to an earth ground (when allowed) may lower the noise
seen in an electrochemical test.
This connection of the Faraday Shield to an earth ground is not a “Protective Earth Ground” as defined in IEC 1010.
The Faraday Shield is safe in the absence of this connection, for it does not contain any hazardous voltages.
Temperature and ventilation
Your Faraday Shield was designed for indoor use at ambient temperatures between 0C and 45C. You may need
to ventilate or even cool the Faraday Shield 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)
• 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 Faraday Shield’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.

Chapter 1: Safety Considerations - Environmental limits
1 - 2
Environmental limits
There are environmental limits on the storage, shipping and operation of this equipment. The Faraday Shield has
not been designed for outdoor use.
Storage
Ambient Temperature –40C to 75C
Relative Humidity Maximum 90% non-condensing
Shipping
Same as storage plus
Acceleration Maximum 30 G
Operation
Ambient Temperature 0C to 45C
Relative Humidity Maximum 90% non-condensing
Use with dangerous materials
Do not use the Faraday Shield with hazardous gases or other poisonous or noxious materials.
Cleaning
When cleaning the Faraday Shield, disconnect any equipment inside from all power sources prior to cleaning.
Use a cloth lightly dampened with either clean water or water containing a mild detergent to clean the outside of
the enclosure. Alternatively, you can use isopropyl alcohol. Do not use a wet rag or allow fluid to enter the
enclosure. Do not immerse the Faraday Shield in any type of cleaning fluid (including water). Do not use any
abrasive cleaners.
Leakage inside
The Faraday Shield is not sealed to be liquid tight. Avoid spills and promptly clean up any spills that do occur.
Caution! The Faraday Shield is not designed for operation in conditions where liquid
water may enter the chassis, or water vapor may condense within the chassis.
Caution! Read and understand the Material Safety Data Sheet (MSDS) for any solvent,
such as isopropyl alcohol, before use. Always take appropriate precautions when using
these materials.
Warning! Do not connect the Faraday Shield unit to poisonous, noxious, or explosive
materials. Failure to observe this warning could cause injury or property damage. The
Faraday Shield is not gas or liquid tight. Use the same precautions as if using an open
electrochemical cell on a bench. Operate in a hood (fume cupboard) if dangerous gases
are used.

Chapter 1: Safety Considerations - RoHS Compliance
1 - 3
RoHS Compliance
The Faraday Shield has been built using lead-free components. This equipment complies with the European RoHS
initiative.

Chapter 2:Introduction
About this manual
This manual covers the installation, safety, and use of the Gamry Instruments Faraday Shield.
About the Faraday Shield
The Faraday Shield is a Faraday cage, designed to be as flexible and convenient as possible for a wide range of
electrochemical experiments.
Faraday Shield features include:
•Pass-throughs for cables, feed gas, thermostatic control (water)
•Electrical isolation from earth ground
•Adjustable plastic shelf for reducing capacitive effects
•Ring stand rod for mounting clamps, various connectors, or adapters to hold glassware, cables, or any
other laboratory equipment
Notational conventions
To make this manual more readable we have adopted some notational conventions. These are used throughout
this manual and all other Gamry Instruments manuals:
•Numbered lists. A numbered list is reserved for step-by-step procedures, with the steps always performed
sequentially.
•Bulleted list. The items in a bulleted list, such as this one, are grouped together because they represent
similar items. The order of items in the list is not critical.

All panel sub-assemblies have their cable entry plates (P/N 810-00123) already pre-mounted.
Initial visual inspection
After you remove your Faraday Shield components from its shipping carton, check all parts for any signs 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.
Assembly

Physical location
Normally place your Faraday Shield on a flat workbench surface. You need access to the top, rear, left, or right side
of the Faraday Shield for cable connections. There are handles on both side and the rear panel to carry the Faraday
Shield.
If you place your Faraday Shield within an enclosed space, make sure that the internal temperature within that
space does not exceed the 45C ambient temperature limit of the Faraday Shield. Be particularly careful if a
computer or other heat-dissipating equipment is mounted in the same enclosure.
Caution! If the Faraday Shield is taken from a cold location (for example: outdoors in
winter conditions) to a warm, humid location, water vapor could condense on the cold
surfaces inside the Faraday Shield. Allow at least one hour for the Faraday Shield to warm
to room temperature.
