step 2. Run the Cable
• T he input from the CB Panel must be 8" from the motor
wiring and 8" from all other electrical wiring. Maintain
the 8" separation when crossing other wiring.
• Cross all branch circuits at 90°.
• The motor wires should exit the building as soon as
possible.
NOTE: The input wiring to the VFD must meet NEC
requirements for a 230V/50 or 60Hz/1ø circuit carrying 15
amps for Model PPC7-1-7A3 or 30 amps for Model PPC7-1-
13A2. For correct wire sizing from the VFD to the motor,
see Table 2, Page 4.
Figure 3A: Correct installation practice. Study the
diagram and run all wiring as shown.
Hazardous voltage inside VFD; can shock,
burn, or kill. Capacitors inside the VFD will hold lethal
voltage even after power has been disconnected. after
disconnecting the power, allow 10 minutes for the
capacitors to discharge before removing the VFD cover.
The ground terminals in the VFD must be connected to
the motor, metal plumbing, or other metal near the motor,
using a wire at least as large as the motor cable wire.
Except for setting parameters and certain testing, disconnect
the incoming power before working on or around the
system. Testing and servicing of the Control must be done
by a qualified electrician.
