Step 1: Read the Precautions

and General Information

Qualified Personnel

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.

Personal Safety

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

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.
