PowerFlex 700S and 700H Frame 12 DC Bus Connector Kit Installation Instructions This document provides instructions for the installation of a DC bus connector kit for PowerFlex 700S and 700H frame 12 drives contained in Rittal TS 8 enclosures only. Important: This kit should only be used for applications that require that the DC and DC+ terminals for PowerFlex 700S or 700H frame 12 drives be connected in common (for example, 12 pulse applications, or when using a dynamic brake). ATTENTION: To avoid an electric shock hazard, ensure that all power has been removed before proceeding. In addition, before servicing, verify that the voltage on the bus capacitors has discharged. Check the DC bus voltage at the Power Terminal Block by measuring between the +DC & -DC terminals, between the +DC terminal and the chassis, and between the -DC terminal and the chassis. The voltage must be zero for all three measurements. ATTENTION: The following information is merely a guide for proper installation. Rockwell Automation, Inc. cannot assume responsibility for the compliance or the noncompliance to any code, national, local or otherwise for the proper installation of this drive or associated equipment. A hazard of personal injury and/or equipment damage exists if codes are ignored. ATTENTION: Only qualified personnel familiar with adjustable frequency AC drives and associated machinery should plan or implement the installation, start-up and subsequent maintenance of the system. Failure to comply may result in personal injury and/or equipment damage. ATTENTION: HOT surfaces can cause severe burns. Do not touch the heatsink surface during operation of the drive. After disconnecting power allow time for cooling. ATTENTION: The sheet metal cover and mounting screws on the ASIC Board located on the power structure are energized at (-) DC bus potential high voltage. Risk of electrical shock, injury, or death exists if someone comes in contact with the assembly.

4 PowerFlex 700S and 700H Frame 12 DC Bus Connector Kit Step 1: Remove Power from the Drive ATTENTION: To avoid an electric shock hazard, verify that the voltage on the bus capacitors has discharged completely before servicing. Check the DC bus voltage at the Power Terminal Block by measuring between the +DC and DC terminals, between the +DC terminal and the chassis, and between the DC terminal and the chassis. The voltage must be zero for all three measurements. 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 input power. Wait five minutes. 2. Verify that there is no voltage at the drive s input power terminals. 3. Check the DC bus voltage at the Power Terminal Block by measuring between the +DC and DC terminals, between the +DC terminal and the chassis, and between the DC terminal and the chassis. The voltage must be zero for all three measurements. L1 L2 L3 I O

Precautions should be taken while installing this kit to ensure that objects do not fall into one of these openings. 1. Optionally, open the enclosure doors and remove the bolts and washers that secure the AC input power cables to terminals 1L1, 1L2 and 1L3, and 2L1, 2L2 and 2L3 at the top of the drive and secure the cables to the top of the enclosure. ATTENTION: A hazard of personal injury and/or equipment damage exists if the AC input power cable insulation becomes damaged and/or fails. Precautions should be taken to ensure that the insulation on the AC input power cables is not damaged during bus bar installation and drive operation. Thoroughly inspect the cable insulation to verify that no damage has occurred after the bus bar kit has been installed. 2. Remove the screws that secure the existing air flow restriction plate to the left enclosure frame and remove the plate. Retain the screws for reuse with the new air flow plate.

Step 17: Complete the Circuit Tests Forward and Reverse Biased Diode Tests for Major Power Components A forward biased diode test checks the semiconductor junctions between the terminals and measures the voltage drop across those junctions. To pass each test, the meter must display a voltage near 0.5V. If the test finds a short, the meter will display.000. If the test finds an open circuit or reversed polarity, the meter will display.0l (zero load). A reverse biased diode test should find an open circuit, and the meter should display.0l (zero load).
