NI cDAQ-9138/9139 Controller

Safety Guidelines

Caution

Do

not

operate the NI cDAQ-9138/9139 controller in a manner not

specified in these operating instructions. Product misuse can result in a hazard. You
can compromise the safety protection built into the product if the product is damaged
in any way. If the product is damaged, return it to National Instruments for repair.

Note

Because some C Series modules may have more stringent certification

standards than the NI cDAQ-9138/9139 controller, the combined system may be
limited by individual component restrictions. Refer to the specifications document
for your cDAQ controller for more details.
