Before You Begin
Before unpacking the product, inspect the shipping carton for damage. If damage is visible,
immediately contact the shipper and request assistance.; otherwise, proceed with unpacking.
Carefully remove the encoder from its shipping container, and visually inspect it for damage. If
the encoder is undamaged, carefully examine the encoder cable and the spring mounting plate for
defects.
Keep the original packing material in case you need to return the product for repair or to
transport it to another location. Use both the inner and outer packing cartons to provide
adequate protection for a unit returned for service.
ATTENTION: Always remove power to all devices, machines, and systems connected to the motor
before connecting or disconnecting cables, or assembling or disassembling the motor and encoder.
Arcing or unexpected motion could occur if the cables are connected or disconnected while power
is applied to the motor.
Observe the professional safety regulations and accident prevention regulations applicable to your
country.
Failure to observe these safety procedures could result in personal injury or damage to the motor
and other equipment.
ATTENTION: Do not strike the shaft, couplings, or pulleys with tools during installation or removal.
Damage may occur to the motor bearings and the encoder if you apply a sharp impact to the shaft
during installation of couplings and pulleys, or a shaft key.
Failure to observe these safety procedures could result in damage to the motor and its
components.
ATTENTION: Do not attempt to open or modify the motor. This manual describes encoder
modifications that you can perform in the field. Do not attempt other changes.
Only a qualified Allen-Bradley employee can service this motor.
Failure to observe these safety procedures could result in personal injury or damage to equipment.
ATTENTION: An unmounted motor, disconnected mechanical couplings, loose shaft keys, and
disconnected cables are dangerous, if power is applied.
Disassembled equipment should be appropriately identified (tagged-out) and access to electrical
power restricted (locked-out). Before applying power, remove the shaft key and other mechanical
couplings that could be thrown from the shaft.
Failure to observe these safety procedures could result in personal injury or damage to equipment.
ATTENTION: The National Electrical Code and local electrical codes take precedence over the
values and methods provided in this document. Implementation of these codes is the
responsibility of the machine builder and the local installer.
