8 Compact I/O Cable for DriveLogix™5730 Controller

Publication 20D-IN008B-EN-P - August 2004

Step 1: Removing Power from Drive and Compact I/O

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 & –DC terminals of the

Power Terminal Block. The voltage must be zero.

Remove power before making or breaking cable connections. When

you remove or insert a cable connector with power applied, an

electrical arc may occur. An electrical arc can cause personal injury or

property damage by:

• sending an erroneous signal to your system’s field devices,

causing unintended machine motion

• causing an explosion in a hazardous environment

Electrical arcing causes excessive wear to contacts on both the

module and its mating connector. Worn contacts may create electrical

resistance.

Task Description

Turn off and lock out input power.

Wait five minutes.

Verify that there is no voltage at

the drive’s input power terminals.

Measure the DC bus voltage at

the +DC & -DC terminals on the

Power Terminal Block. The voltage

must be zero.
