HAZARDOUS HIGH VOLTAGE
Motor control equipment or electronic controllers are connected to hazardous line
voltages. When servicing drives and electronic controllers there migh exist exposed
components with cases or protrusions at or above line potential. Extreme care should
be taken to protect against shock.
For these reasons, the following safety guidelines should be observed:
Stand on an insulating pad and make it a habit to use only one hand when checking
components. Disconnect power before checking controllers or performing
maintenance. Be sure that equipment is grounded properly. Wear safety glasses
whenever working on an electronic controller or rotating electrical equipment.
WARNING This equipment should be installed, adjusted and serviced only by qualified electrical
maintenace personnel familiar with the construction and operation of the equipment
and the hazards involved. Failure to observe this precaution could result in bodily
injury.
WARNING The user is responsible that all driven machinery, drive train mechanism not supplied
by Hitachi, Ltd., and process line material are capable of safe operation at an applied
frequency of 150% of the maximum selected frequency range to the AC motor. Failure
to do so can result in destruction of equipment and injury to personnel should a single
point failure occur.
