Chapter 1: Safety Considerations
Introduction
The Gamry Instruments TDC5 is based on a standard temperature controller, the Omega Engineering Inc.
Model CS8DPT. Gamry Instruments has performed slight modifications of this unit to allow easier incorporation
of it into an electrochemical test system.
Omega prov
ides a User’s Guide that covers safety issues in
detail. In most cases, the Omega information is not
duplicated here. If you do not have a copy of this document, contact Omega at

Your TDC5 Temperature Controller has been supplied in a safe condition. Consult
the Omega User’s Guide to
ensure continued safe operation of this device.
Inspection
When you receive your TDC5 Temperature Controller, inspect it for evidence of shipping damage. If you note
any damage, please notify Gamry Instruments Inc. and the shipping carrier immediately. Save the shipping
container for possible inspection by the carrier.
As defined in IEC Publication 348, Safety Requirements for Electronic Measuring Apparatus, the TDC5 is a Class
I apparatus. Class I apparatus is only safe from electrical shock hazards if the case of the apparatus is connected
to a protective earth ground.
In the TDC5 this protective ground connection is made via the ground prong in the AC line cord. When you
use the TDC5 with an approved line cord, the connection to the protective earth ground is automatically made
prior to making any power connections.
The TDC5 is supplied with a line cord suitable for use in the United States. In other countries, you may have to
replace the line cord with one suitable for your electrical outlet type. You must always use a line cord with a
Warning:
If the protective ground is not properly connected, it creates a safety hazard,
which could result in personnel injury or death. Do not negate the protection of this earth ground by any
means. Do not use the TDC5 with a 2 wire extension cord, with an adapter that does not provide for
protective grounding, or with an electrical outlet that is not properly wired with a protective earth ground.
Warning:
A TDC5 Temperature Controller damaged in shipment can be a safety hazard.
The protective grounding can be rendered ineffective if the TDC5 is damaged in shipment. Do not operate
damaged apparatus until a qualified service technician has verified its safety. Tag a damaged TDC5 to
indicate that it could be a safety hazard.
