Installation Instructions

PowerFlex® 700L Frame 3A and 3B Input Filter Precharge Resistor Kit (20L-RESPRE-A1)

ATTENTION: To avoid an electric shock hazard, ensure that all power to the complete drive cabinet has been removed before

performing any steps of these instructions.

ATTENTION: To avoid an electric shock hazard, verify that the voltage on the bus capacitors has completely discharged before

performing any work on the complete drive cabinet. After removing power, wait 5 minutes for the power module bus capacitors to discharge. Remove the lower front cover of the power module. Measure the DC bus voltage at the DC+ TESTPOINT and DC- TESTPOINT sockets on the front of the power module. The voltage must be zero.

ATTENTION: HOT surfaces can cause severe burns. Do not touch the heatsink surface during operation of the power module.

After disconnecting power allow time for cooling.

ATTENTION: The complete drive cabinet contains ESD (Electrostatic Discharge) sensitive parts and assemblies. Static

control precautions are required when installing, testing, servicing or repairing the complete drive. Component damage may result if ESD control procedures are not followed. If you are not familiar with static control procedures, refer to Allen-Bradley publication 8000-4.5.2, “Guarding Against Electrostatic Damage” or any other applicable ESD protection handbook.

This kit can only be used with PowerFlex 700L Frame 3A and 3B complete drives. It is used to increase the precharge power capacity of the drive. This kit may be required when powering another drive from the DC bus of a Frame 3A or 3B complete drive. Only one kit per drive is permitted. See the tables below for comparisons of maximum DC bus capacitance.

Parameter 162 - [Capacitance] of the PowerFlex 700L Active Converter must be set to the total DC bus capacitance of the PowerFlex 700L complete drive plus the other drives connected to the DC bus.

Step 1: Removing Power from the Complete Drive

ATTENTION: To avoid an electric shock hazard, verify that the voltage on the bus capacitors has completely discharged before

Remove power before making or breaking cable connections. When you remove or insert a cable connector with power applied, an electrical arc may occur, which 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 complete drive input power. Wait 5 minutes.

L1 L2 L3

2. Verify that there is no voltage at the complete drive’s input power

terminals.

3. Remove the lower front cover of the power module. Loosen the two (2)

captive screws and pull the cover off the power module. Set the cover aside to be reinstalled later.

4. Measure the DC bus voltage at the DC+ TESTPOINT and DC-

TESTPOINT sockets on the front of the power module chassis. The voltage must be zero.
