Installation and Wiring
EMC Considerations
The DriveGuard Safe Torque Off option and PF40P and PF70 drives may be
installed in an industrial electromagnetic environment which is consistent
with the “Second Environment” described in IEC 61800-3 and where the
EMC requirements documented in the PF40P and PF70 Installation manuals
have been satisfied. Important installation requirements include:
•
All motor output, control (I/O) and signal wiring for the drive and
DriveGuard Safe Torque Off option must be shielded cable
•
Grounding (earthing) must conform to the requirements described in the
drive user manuals

1.
Remove all power to the drive.
ATTENTION: To avoid an electric shock hazard, verify that the voltage on the bus
capacitors has discharged before performing any work on the drive. Measure the DC bus
voltage at the +DC and -DC terminals or test points (refer to your drive’s User Manual for
locations). The voltage must be zero.
