Installation Instructions
Second Encoder Option Card for PowerFlex®
700S Drives with Phase II Control
ATTENTION: To avoid an electric shock hazard, verify that the
voltage on the bus capacitors has discharged before performing
!
any work on the drive. Measure the DC bus voltage at the +DC &
–DC terminals of the Power Terminal Block. The voltage must
be zero.
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: This drive contains ESD (Electrostatic
Discharge) sensitive parts and assemblies. Static control
!
precautions are required when installing, testing, servicing or
repairing this assembly. Component damage may result if ESD
control procedures are not followed. If you are not familiar with
static control procedures, reference A-B publication 8000-4.5.2,
“Guarding Against Electrostatic Damage” or any other
applicable ESD protection handbook.

ATTENTION: To avoid an electric shock hazard, verify that the
voltage on the bus capacitors has discharged before performing
!
any work on the drive. Measure the DC bus voltage at the +DC &
–DC terminals of the Power Terminal Block. The voltage must
be zero.
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.
Task Description
Turn off and lock out input power. Wait five minutes.
