Getting Started with the cDAQ Controller
4.
Connect a computer keyboard and mouse to the bottom two USB ports on the cDAQ
controller.
5.
Attach a ring lug to a 1.31 mm
2
(16 AWG) or larger wire. Remove the ground screw from
the ground terminal on the front panel. Attach the ring lug to the ground terminal and
tighten the grounding screw to 0.5 N · m (4.4 lb · in.) of torque. Attach the other end of the
wire to chassis safety ground using a method appropriate for the application, as shown in
Figure 1-2. Refer to the
section for more information about earth
ground.
Note
If you use shielded cabling to connect to a C Series module with a plastic
connector, you must attach the cable shield to the chassis grounding terminal using
1.31 mm
2
(16 AWG) or larger wire. Use shorter wire for better EMC performance.
Figure 1-2.
Ring Lug Attached to Ground Terminal
Note
Make sure that no I/O-side power is connected to the module. If the controller
is in a nonhazardous location, the controller power can be on when you install
modules.
6.
Align the module with a cDAQ controller slot. The module slots are labeled 1 to 8, left to
right.
7.
Squeeze the latches and insert the module into the module slot, and press firmly on the
connector side of the module until the latches lock the module into place.
Repeat these steps to install additional modules.
