4.3.1 CVS4200 Wiring Procedure
1. Remove the hood from chassis. The terminals for field connections are
located along the back of the tray (11 on FIGURE 5-2). If the sampler has
been provided with a refrigerator, the power plug is also located here.
2. Route cabling from external devices through the clearance holes and
connect to the terminal block (see FIGURE 4-2).
Use shielded cables for wiring remote/external functions and
terminate the shield at the AC ground terminal on the sampler
main terminal block, or at the remote site, but not both. NOTE
3. Bring power from main distribution panel along a path that does not
parallel any existing power wiring to motors, solenoids, or contactors.
When sampler power line must cross existing power lines, do so at right
angles.
4. Replace hood.
