Wiring Power to the cDAQ Chassis

Caution
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.
The cDAQ chassis requires an external power source as described in the Power Requirements
section of the specifications document for your cDAQ chassis. Some suggested NI power
supplies are listed in Table 1-8. The cDAQ chassis filters and regulates the supplied power and
provides power to all of the modules. The green POWER LED on the front panel identifies when
the power input is in use.
Complete the following steps to connect a power source to the cDAQ chassis.
1. Make sure the power source is turned off.
2. If connected, loosen the connector screw flanges and remove the power screw terminal
connector plug from the cDAQ chassis. Figure 1-9 shows the terminal screws, which secure
the wires in the screw terminals, and the connector screw flanges, which secure the
connector plug on the front panel.
