PowerFlex 700 Adjustable Frequency AC Drive – Frames 0…6
Step 1: Read the Precautions
and General Information
Qualified Personnel
Personal Safety
ATTENTION:
Only qualified personnel familiar with adjustable frequency AC
drives and associated machinery must plan or implement the installation, start-
up and subsequent maintenance of the system. Failure to comply can result in
personal injury and/or equipment damage.
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 following points (refer to pages
28
through
30
for locations):
•
+DC and -DC terminals of the Power Terminal Block
•
+DC terminal of the Power Terminal Block and the chassis
•
-DC terminal of the Power Terminal Block and the chassis
The voltage must be zero for all three measurements.
ATTENTION:
Risk of injury or equipment damage exists. DPI or SCANport host
products must not be directly connected together via 1202 cables.
Unpredictable behavior can result if two or more devices are connected in this
manner.
ATTENTION:
The drive start/stop/enable control circuitry includes solid state
components. If hazards due to accidental contact with moving machinery or
unintentional flow of liquid, gas or solids exist, an additional hardwired stop
circuit can be required to remove the AC line to the drive. An auxiliary braking
method can be required.
ATTENTION:
Loss of control in suspended load applications can cause personal
injury and/or equipment damage. Loads must always be controlled by the drive
or a mechanical brake. Parameters 600…611 are designed for lifting/torque
proving applications. It is the responsibility of the engineer and/or end user to
configure drive parameters, test any lifting functionality and meet safety
requirements in accordance with all applicable codes and standards.
