Safety Considerations
13
RF Warning
The EIS Box has been tested for both radiated and conducted RF interference and for immunity to RF fields,
and has been found to be in compliance with FCC Part 18 and EU Council Directive 2014/30/EU, the EMC
Directive EN 61326:2013
— Electrical equipment for measurement, control, and laboratory use — EMC
Requirements. Testing was performed in accordance with the Basic Immunity Requirements contained in Table
1 and the Emission Requirements contained in Section 7.
However, your EIS Box instrument still does generate some radio-frequency energy. The radiated levels are low
enough that the EIS Box should not create an interference problem in most industrial laboratory environments.
Your EIS Box instrument may also respond to environmental radio-frequency energy. We recommend you
avoid using mobile phones and other radio-frequency equipment in the same room as an EIS Box. The EIS Box
circuitry has been tested for operation in high-intensity RF fields and has demonstrated little response to those
fields. However, there is no guarantee that the electrochemical cell and its connections will not respond to RF
fields. This response most often appears as DC shifts in a cell
’ s response caused by rectification of the RF signal.
A Faraday cage surrounding your cell may be used to minimize the effect of environmental RF fields. If your cell
is isolated from earth ground, Gamry recommends connecting the
System Ground to a Faraday cage.
Electrical Transient Sensitivity
Your EIS Box instrument was designed to offer reasonable immunity from electrical transients, including
transients on the incoming AC mains supply and electrostatic discharge. It has been tested for compliance with
EN 61326-1:2013
— Electrical equipment for measurement, control, and laboratory use — EMC Requirements
describing acceptable limits for electrical transient susceptibility in laboratory test equipment. It should continue
to operate when subject to the standard ESD and power-line events defined in EN 61326-1:2013.
In severe cases involving transients beyond the limits tested in EN 61326-1:2013, the EIS Box could still
malfunction as a result of electrical transients. If you are having problems in this regard, the following steps may
help:
If the problem is static electricity (sparks are apparent when you touch the EIS Box or its cables):
• Try placing your EIS Box on a static-control work surface. Static-control work surfaces are now generally
available from computer-supply houses and electronics-tool suppliers. An antistatic floor mat may also
help, particularly if a carpet is involved in generating the static electricity.
• Air-ionizers or even simple air-humidifiers can reduce the voltage available in static discharges.
If the problem is AC power-line transients (often from large electrical motors near the EIS Box):
• Try plugging your EIS Box into a different AC power branch circuit.
• Plug your EIS Box into a power-line surge-suppressor. Inexpensive surge-suppressors are now generally
available because of their use with computer equipment.
Contact Gamry Instruments, Inc. if these measures do not solve the problem.
CE Compliance
The European Community has instituted standards limiting radio-frequency interference emitted by electronic
devices, setting limits for susceptibility of apparatus to RF energy and transient events, and mandating safety
requirements. Gamry Instruments, Inc. has designed and tested the EIS Box to comply with these standards.
The relevant CE regulations include EN 61010-1:2010 and EN 61326-1:2013.
RoHS Compliance
The EIS Box is built using lead-free components and lead-free solder. It complies with the European RoHS
initiative.
