Gamry Reference 3000 - Defects and Abnormal Stresses; Environmental Limits

Chapter 1 -- Safety Considerations--Defects and Abnormal Stresses
1 - 4
The Reference 3000 uses forced air-cooling to keep its electronic components within their recommended
operating temperature range. Three fans on the rear panel of the Reference 3000 draw air into the chassis.
The air exits from slots located on the sides of the chassis near the front panel.
Be careful when operating the Reference 3000 in an enclosed space (such as an enclosed relay rack or NEMA
enclosure). The temperature within the enclosure must not exceed 45°C. You may need to provide ventilation
holes or even forced air-cooling for the enclosed space if you determine that there is an excessive temperature
rise within the space.
Defects and Abnormal Stresses
You should treat your Reference 3000 as potentially hazardous if any of the following is true of the unit:
• it shows visible damage,
• it does not operate properly,
• it has been stored for a long period of time under unfavorable conditions,
• it has been dropped or subjected to severe transport stress,
• it has been subjected to environmental stress (corrosive atmosphere, fire, etc.).
Do not use your Reference 3000 or any other apparatus if you think it could be hazardous. Have it checked by
qualified service personnel.
Environmental Limits
Note that there are environmental limit conditions on the storage, shipping and operation of this equipment.
The Reference 3000 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
CAUTION
Do not block the airflow into or out of the Reference 3000 chassis. While the circuitry
should shut down before it is damaged from excessive heat, the Reference 3000
enclosure may become uncomfortably hot to the touch if insufficient air flows through
the chassis. Running the Reference 3000 without adequate cooling could shorten the
time to failure of some of the circuitry.
