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

to prevent the risk of serious injury or fatality. Use a non-
