Safety:

Moog motors are capable of producing high forces and velocities. Always
follow appropriate safety precautions when installing and applying these motors.
Equipment should be designed and utilized to prevent personnel from coming in
contact with moving parts that could potentially cause injury.

Read the Moog Linear Motor User’s Manual which applies to the motor you are using
before attempting to operate this device.

Read all cautions, warnings and notes before attempting to operate this device.

Follow all applicable codes and standards.
