PCI-1724U User Manual 28

If the cable travels through an area with significant electromagnetic inter-

ference, you should adopt individually shielded, twisted-pair wires as the

analog input cable. This type of cable has its signal wires twisted together

and shielded with a metal mesh. The metal mesh should only be con-

nected to one point at the signal source ground.

Avoid running the signal cables through any conduit that might have

power lines in it.

If you have to place your signal cable parallel to a power line that has a

high voltage or high current running through it, try to keep a safe distance

between them. Alternatively, you can place the signal cable at a right

angle to the power line to minimize the undesirable effect.

The signals transmitted on the cable will be directly affected by the qual-

ity of the cable. In order to ensure better signal quality, we recommend

that you use the PCL-10162 shielded cable.
