Preparing the Environment
Ensure that the environment you are using the NI cDAQ-9188 in meets the following specifications.
Operating temperature (IEC 60068-2-1 and IEC 60068-2-2)
-20 °C to 55 °C
2
Caution
To maintain product performance and accuracy specifications when the ambient temperature is between 45 and 55 °C, you must mount the
chassis horizontally to a metal panel or surface using the screw holes or the panel mount kit. Measure the ambient temperature at each side of the
CompactDAQ system 63.5 mm (2.5 in.) from the side and 25.4 mm (1.0 in.) from the rear cover of the system. For further information about mounting
configurations, go to

Electromagnetic Compatibility Guidelines
This product was tested and complies with the regulatory requirements and limits for electromagnetic compatibility (EMC) stated in the product specifications.
These requirements and limits provide reasonable protection against harmful interference when the product is operated in the intended operational
electromagnetic environment.
This product is intended for use in industrial locations. However, harmful interference may occur in some installations, when the product is connected to a
peripheral device or test object, or if the product is used in residential or commercial areas. To minimize interference with radio and television reception and
prevent unacceptable performance degradation, install and use this product in strict accordance with the instructions in the product documentation.
Furthermore, any changes or modifications to the product not expressly approved by National Instruments could void your authority to operate it under your
local regulatory rules.
Caution
To ensure the specified EMC performance, product installation requires either special considerations or user-installed add-on devices. Refer
to the
NI cDAQ-9181/9184/9188/9191 User Manual
for further information.
Caution
To ensure the specified EMC performance, operate this product only with shielded cables and accessories. Note that the input DC power
cables may be unshielded.
Caution
To ensure the specified EMC performance, do not connect the power connector to a DC MAINS supply or to any supply requiring a
connecting cable longer than 3 m (10 ft). A DC MAINS supply is a local DC electricity supply network in the infrastructure of a site or building.
Caution
To ensure the specified EMC performance, the length of any I/O cable connected to a BNC PFI port must be no longer than 30 m (100 ft).
Special Conditions for Marine Applications
Some products are Lloyd’s Register (LR) Type Approved for marine (shipboard) applications. To verify Lloyd’s Register certification for a product, visit
and search for the LR certificate, or look for the Lloyd’s Register mark on the product.
Caution
In order to meet the EMC requirements for marine applications, install the product in a shielded enclosure with shielded and/or filtered
power and input/output ports. In addition, take precautions when designing, selecting, and installing measurement probes and cables to ensure that the
desired EMC performance is attained.
