Installation Instructions
TL-Series Motor Transition Plate
(Catalog Numbers TL-TRPLAT-17-23, TL-TRPLAT-23-34, and
TL-TRPLAT-34-42)
This publication provides instructions to attach the TL-Series Transition
Plates to TL-Series NEMA motors.
The TL-Series Motor Transition Plate allows a TL-Series NEMA motor
to physically replace an N-Series motor. It converts the mounting bolt
hole pattern from a TL-Series NEMA pattern to an N-Series NEMA
bolt hole pattern. This allows the original mounting holes in the
machine to be used to mount the replacement motor.
This document applies to the transition plates, motors, and mounting
hardware identified by these catalog numbers:

Installation Instructions
To attach an transition plate to a TL-Series NEMA motor:
ATTENTION
1. Align the mounting holes in the transition plate with those in the
TL-Series NEMA motor.
2. Insert the mounting screws from the proper direction, and then torque
each screw to the appropriate value.
• TL-TRPLAT-17-23 requires two screws through the face of the
transition plate and into the front of the motor mount.
• TL-TRPLAT-23-34 and TL-TRPLAT-34-42 require four screws
through the back of the motor mount and into the rear of the
transition plate.
Energy may be stored in a drive system after power is
removed.
Before disconnecting mechanical or electrical connections
to a motor, remove power from the drive system and allow
the bus capacitance to discharge for the time indicated on
the front of the drive.
Failure to observe safety procedures could result in personal
injury or equipment damage.
