Hazardous High Voltage
WARNING
Motor control equipment and electronic controllers are
connected to hazardous line voltages. When servicing
drives and electronic controllers, there may be exposed
components with housings or protrusions at or above
line potential. Extreme care should be taken to protect
against shock.
Stand on an insulating pad and make it a habit to use only
one hand when checking components. Always work with
another person in case an emergency occurs. Disconnect
power before checking controllers or performing
maintenance. Be sure equipment is properly grounded. Wear
safety glasses whenever working on electronic controllers or
rotating machinery.

This manual contains clearly marked cautions and warnings
which are intended for your personal safety and to avoid any
unintentional damage to the product or connected
appliances.
Please read the information included in cautions and
warnings carefully.

The current-dependent protective device must be selected
so that not only is the motor current monitored but the
blocked motor is switched OFF within the temperature rise
time.
