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. The Faraday Shield has a conductive coating on the
outer side of the glass pane in the door. If the glass is cracked, the
conductivity could be broken, compromising the Faraday Shield’s ability to
function as a Faraday cage.
Warning! The door of the Faraday Shield 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.
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.
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. 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.
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.
Temperature and ventilation
Your Faraday Shield was designed for indoor use at ambient temperatures
between 0C and 45C. You may need to ventilate or even cool the Faraday
Shield with forced air if the temperature rises excessively.
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 Relative Humidity –40C to 75C Maximum 90% non- condensing
Shipping
Same as storage plus Acceleration Maximum 30 G
Operation
Ambient Temperature Relative Humidity 0C to 45C Maximum 90% non- condensing
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.
Use with dangerous materials
Do not use the Faraday Shield with hazardous gases or other poisonous or
noxious 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.
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.
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.
Leakage inside
The Faraday Shield is not sealed to be liquid tight. Avoid spills and promptly
clean up any spills that do occur.
RoHS Compliance
The Faraday Shield has been built using lead-free components. This equipment
complies with the European RoHS initiative.

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 sides 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
45C 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.
