700L Frame 3A and 3B Input Filter
Precharge Resistor Kit (20L-RESPRE-A1)
Where This Kit Is Used 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.
!
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.
