LOW VOLTAGE / DC CONTROL WIRING 230 VAC SUPPLY / LOAD WIRING
1. Improper wiring to the transducer will destroy the transducer. Use caution to ensure that the wiring to the transducer is correct before activating the CPC-3 controller. 2. Verify that the input power voltage matches the VFD's nameplate rating before applying power. Improper supply voltage to the VFD could damage the VFD.
460 VAC SUPPLY / LOAD WIRING VFD COMMUNICATIONS CABLE FIGURE 8052020 11/18/04
3. Verify that the blower (VSUB 8/12/16/20) is wired for the output voltage from the VFD. If not correct, severe damage to the blower and/or the VFD could result. 4. When the system is completely installed, perform the safety interlock and operational test as outlined in the installation manuals. Failure to do these tests could result in an unsafe and/or incorrectly operating system.

460 VAC / 3Ø / 60 HZ
1. All wiring must be in metal conduit (best) or shielded cable.
"4" means "460 VAC" "C" means "Closed Loop"
2. Route transducer wiring in metal conduit or use Belden Shield Cable #9939 or equivalent. Make sure the transducer wiring does not contain or cross line voltage wiring or undesired transducer performance may result. 3. Do not run the VFD's input power and output power wiring in the same conduit. Undesired VFD operation could result.
