Preparing to Wire to a Screw Terminal
Panel
Wiring Recommendations
• Use individually shielded twisted-pair wire (size 14 to 26 AWG)
when using a DT3010 Series board in highly noisy electrical
environments.
• Separate power and signal lines by using physically different
wiring paths or conduits.
• To avoid noise, do not locate the screw terminal panel and
cabling next to sources that produce high electro-magnetic fields,
such as large electric motors, power lines, solenoids, and electric
arcs, unless the signals are enclosed in a mumetal shield.
• On the DT740 screw terminal panel, it is recommended that you
connect the shields as follows:
−
Connect the analog shield to screw terminals TB35 and TB36,
and to TB51 through TB56.
−
Connect the digital shield to screw terminals TB105 and
TB108.
−
Connect the analog and digital shields to one end only.
CAUTION:
To avoid electrical damage, ensure that power is turned off to the
computer and to any attached devices before wiring signals to the
DT740 screw terminal panel.
