Introduction
Scope of Manual
This instruction manual provides product information including installation for the Fisher easy-Drive
RPU-100. For Fisher easy-Drive actuators refer to the appropriate easy-Drive actuator instruction
manual. To avoid personal injury or property damage, it is important to carefully read, understand, and
follow all the contents of this manual, including all safety cautions and warnings. If you have any
questions about these instructions, contact your
Description
The easy-Drive RPU-100 is a reserve power unit designed to provide backup power to the easy-Drive actuator upon
loss of incoming power. The RPU-100 provides enough power to the actuator to allow the actuator to drive the valve
to the pre-defined loss of power or loss of signal position. The RPU-100 can be ordered with a new easy-Drive assembly
or be retrofit into existing easy-Drive units that have the Gen2 control board.
