HAZARDOUS HIGH VOLTAGE
Motor control equipment or electronic controllers are connected to hazardous line voltages.
When servicing drives and electronic controllers there might 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

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 WATT Drive
Antriebstechnik GmbH 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.
WARNING
HAZARD OF ELECTRICAL SHOCK. DISCONNECT INCOMING POWER BEFORE WORKING ON THIS
CONTROL.
WARNING
SEPERATE MOTOR OVERLOAD AND OVERCURRENT PROTECTION DEVICES ARE REQUIRED TO
BE PROVIDED IN ACCORDANCE WITH THE SAFETY CODES REQUIRED BY JURISDICTIONAL
