-- Safety Considerations
Introduction
The Gamry Instruments TDC4 is based on a standard temperature controller, the Omega Engineering Inc.
Model CSi8D. Gamry Instruments has performed slight modifications of this unit to allow easier
incorporation of it into an electrochemical test system.
Omega provides a User’s Guide that covers safety issues in detail. In most cases, the Omega information
will not be duplicated here. If you do not have a copy of this document, it can be obtained by
contacting Omega at

.
Your TDC4 Temperature Controller has been supplied in a safe condition. Consult the Omega User’s
Guide to insure continued safe operation of this device.
Inspection
When you receive your TDC4 Temperature Controller you should 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.
Warning
The protective grounding can be rendered ineffective if the TDC4 is
damaged in shipment. Do not operate damaged apparatus until its safety
has been verified by a qualified service technician. Tag a damaged TDC4 to
indicate that it could be a safety hazard.
Protective Grounding and Product Safety
As defined in IEC Publication 348, Safety Requirements for Electronic Measuring Apparatus, the TDC4 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 TDC4 this protective ground connection is made via the ground prong in the AC line cord. When
you use the TDC4 with an approved line cord, the connection to the protective earth ground is
automatically made prior to making any power connections. Do not negate the protection of this earth
ground by any means. Do not use the TDC4 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
If the protective ground is not properly connected, it creates a safety
hazard, which could result in personnel injury or death.
