Rockwell Automation LiquiFlo 1.0 and 1.5 External Bus Resistor Kit (1200 Amp) - Manual (Page 2)

2 Instruction Manual D2-3537
What You Need to Do To install the external bus resistor kit you need to:
❐ Step 1: Verify that the DC Bus Capacitors are discharged
❐ Step 2: Identify a mounting location for the resistor assemblies
❐ Step 3: Drill mounting holes for the resistor assemblies, using the
template
❐ Step 4: Mount the resistor assemblies
❐ Step 5: Locate the connection points, and route harness
❐ Step 6: Connect the ground wires
❐ Step 7: Connect the J4, J4A and J4B
❐ Step 8: Connect the harness to the capacitor bank
❐ Step 9: Verify installation
❐ Step 10: Register installation
Step 1: Verifying the DC Bus
Capacitors are Discharged
!
ATTENTION: DC Bus capacitors retain hazardous voltages
after input power has been disconnected. After disconnecting
input power, wait five (5) minutes for the DC bus capacitors to
discharge and then check the voltage with a voltmeter to ensure
that the DC bus capacitors are discharged before touching any
internal components. Failure to observe this precaution could
result in severe bodily injury or loss of life.
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
Remove front cover
Measure the DC bus potential with a voltmeter while standing on a non-conductive surface
and wearing insulated gloves (1000V)
