Introduction

Compatibility

This document explains the recommended procedures that you should use when joining and splicing a PowerFlex® 755 Floor-mount drive, Frames 8…10, with a CENTERLINE® 2100 Motor Control Center (MCC).

Before you begin, familiarize yourself with the installation requirements and recommendations for both the PowerFlex 755 drive and the CENTERLINE 2100 MCC.

The transition section and splicing kit is designed to join together a PowerFlex 755 floor-mount drive and a CENTERLINE 2100 MCC column with or without 1.5 inch mounting channels.

Diagrams in this publication show the mounting channels installed. Mounting channels will not be used in all installations.

A complete installation requires one transition section and one bus bar splicing kit. Depending on the catalog number ordered, the kit will be a left-side mount or a right-side mount relative to the drive. Kits include all joining and splicing hardware. An IP20, NEMA/UL Type 1 enclosure results when kits are installed according to these instructions. If a NEMA Type 12 structure is required, follow the CENTERLINE Motor Control Centers NEMA Type 12 Sealing Instructions, publication 2100-IN037

Remove Power from All Equipment

Remove power from all equipment before proceeding with these instructions. Refer to the product’s installation instructions and review all safety precautions before performing work on this equipment.

PowerFlex 755 Drive

ATT EN TI ON : To avoid an electric shock hazard, verify that the voltage on the

bus capacitors has discharged completely before servicing. Measure the DC bus voltage at the -DC and +DC TESTPOINT sockets on the front of the power module (see Figure 1

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.

1. Turn off and lock out all input power, including any and all external power sources.

for location).

2. Wait 15 minutes and verify that there is no voltage at the drive’s input power terminals.

3. Measure the DC bus voltage at the -DC and +DC TESTPOINT sockets on the front of the power module.

CENTERLINE 2100 MCC

ATT EN TI ON : De-energize all units before installing or removing.

When installing or removing MCC units, when possible, deenergize, lockout, and tag-out all sources of power to the MCC.

ATT EN TI ON : De-energize all power sources to the motor control center before joining and splicing with the drive. Failure to de-energize all power sources can result in severe injury or death. Using a voltmeter, verify that the MCC remote power sources are disconnected.

IMPORTANT

Joining Drive, Transition Section, and MCC

Physical restrictions at your installation may not allow the following sequence to be followed exactly as stated.

Step 1: Remove Drive Assembly

The PowerFlex 755 drive assembly must be removed to access side panels and horizontal bus bars.

For detailed information on removing and handling the PowerFlex 755 drive assembly, refer to the PowerFlex 750-Series AC Drives Installation Instructions, publication 750-IN001

ATT EN TI ON : This drive has a high center of gravity and a tip-over hazard exists. To guard against death, serious personal injury, and/or equipment damage, do not subject the drive to high rates of acceleration or deceleration while transporting. Do not push or pull above the points indicated on the drive.

. Special equipment is required.

Step 2: Remove Plug-in Units, Support Pans, and Access Covers

All plug-in units and support pans must be removed to access side panels and horizontal bus bars.

ATT EN TI ON : Plug-in MCC units may be heavy or awkward to handle. Use an assistant or a platform lift device if necessary to help you handle the unit

To complete plug-in unit removal refer to Installing Units with Horizontal Operating Handles, publication 2100-IN060 Operating Handles, publication 2100-IN014

ATT EN TI ON : MCCs are top and front heavy. To avoid personal injury or structural damage, never attempt to lift or move the MCC by any means other than the methods outlined in Receiving and Storing Motor Control Centers, publication 2100-IN040

If you’re installing a left-mount kit, see page 7

If you’re installing a right-mount kit, see page 14
