2.5 Environmental requirements
Note: This section applies to all Series 3000 devices.
In addition to the temperature requirements described in the QRG, the following environmental
requirements apply:
• Humidity: 5 to 95% relative humidity, non-condensing at 140 °F (60 °C)
• Vibration: Meets IEC 68.2.6, endurance sweep, 5 to 2000 Hz, 50 sweep cycles at 1.0 g
If possible, install the Series 3000 device in a location that will prevent the heating effects of direct
exposure to sunlight.
2.6 Ingress protection for Model 3300 controller
Note: This section applies only to Model 3300 controllers.
If you are installing the Model 3300 in a panel cutout, it may be installed outdoors, if it is installed in
a panel providing a degree of ingress protection IP 65 according to EN 50529 (IEC 529).
If you are installing the Model 3300 in a rack, it should be installed in a rack providing a degree of
ingress protection NEMA 4X according to EN 50529 (IEC 529).
2.7 Frequency input cable length
Note: This section applies only to Model 3300 or Model 3350 controllers.
The maximum length of the frequency input cable has been increased. The maximum length is now
1000 feet (300 meters) of typical 18 AWG (0,80 mm

) instrumentation cable, rather than 500 feet
(150 meters) as documented in the QRGs.
WARNING
Explosion Hazard.
Do not open wiring compartments when an explosive gas atmosphere is
present.
Do not remove the compartment covers in an explosive atmosphere within three
minutes after power is disconnected.
WARNING
Using a dry cloth to clean the display cover can cause static discharge,
which could result in an explosion in an explosive atmosphere.
To prevent an explosion, use a clean, damp cloth to clean the display cover in an
explosive atmosphere.
