It is possible for a drive to run at full speed as a result
of a component failure. LEESON strongly recommends
the installation of a master switch in the main power input to
stop the drive in an emergency.
This drive is not isolated from earth ground. Circuit
potentials are at 115 VAC above earth ground. Avoid direct
contact with the printed circuit board or with circuit elements
