Keep this manual handy for quick reference. It calls your attention to items or operations that could be dangerous to you and other persons operating this equipment.
Read the message and follow the instructions carefully. CAUTION: Indicates a potentially hazardous situation that, if not avoided, can result in minor to moderate injury or serious damage to the product. Step 1: Indicates a step in a series of action steps required to accomplish a goal. The number of the step will be contained in the step symbol. TIP: Tips give a special instruction that can save time or provide other benefits while installing or using the product.
The tip calls attention to an idea that may not be obvious to first-time users of the product. When servicing drives and electronic controllers, there may be exposed components with housing 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. Caution when using Safe Stop Function When using Safe Stop function, make sure to check whether the safe stop function properly works when installation before starting operation. Please carefully refer to page Appendix E 3. WARNING: This equipment should be installed, adjusted, and serviced by qualified electrical maintenance personnel familiar with the construction and operation of the equipment and the hazards involved.
Failure to observe this precaution could result in bodily injury. Failure to do so can result in destruction of equipment and injury to personnel should a single-point failure occur. WARNING: For equipment protection, install a ground leakage type breaker with a fast response circuit capable of handling large currents. The ground fault protection circuit is not designed to protect against personal injury.
Otherwise, there is the danger of electric shock. CAUTION: Be sure to connect a motor thermal disconnect switch or overload device to the WJ series controller to assure that the inverter will shut down in the event of an overload or an overheated motor. Wait at least five 5 minutes after input power is disconnected before performing maintenance. Therefore, it is strongly recommended that all electrical work conform to the National Electrical Codes and local regulations.
Installation, alignment and maintenance should be performed only by qualified personnel. In this event suitable protection must be provided. When removing the front cover for maintenance or inspection, confirm that incoming power for alarm connection is completely disconnected.
The end application must be in accordance with BS EN The diagram dimensions are to be suitably amended for your application.
Use a termination with cable support figure below , or strain relief, cable clamp, etc. Disconnect incoming power before working on this control. Wait five 5 minutes before removing the front cover. Never touch the naked PCB printed circuit board portions while the unit is powered up. Even for switch portion, the inverter must be powered OFF before you change. The power supply capacity is at least 10 times greater than the inverter capacity or the power supply capacity is kVA or more.
Abrupt power supply changes are expected, due to the conditions such as: a. Several inverters are interconnected with a short bus. A thyristor converter and an inverter are interconnected with a short bus.
An installed phase advance capacitor opens and closes. Otherwise, there is the danger of fire. Otherwise, it may fall and cause injury to personnel.
Otherwise, it may cause injury to personnel. Otherwise, the inverter may overheat and cause equipment damage or fire.
For models with suffix S, N or L. If the drive has been powered, leave it OFF for five minutes before continuing. Pay attention when wiring the power cable. Check for any loosening of screws. Otherwise, there is the possibility of damage to the inverter and the danger of fire. Especially at the moment of switching ON this can cause an inadvertent trip of ground fault interrupters. Because of the rectifier on the input side of the inverter there is the possibility to stall the switch-off function through small amounts of DC current.
Be careful not to touch them. Otherwise, there is the danger of getting burned. Be sure to check the capability and limitations of the motor and machine before operating the inverter.
Otherwise, there is the danger of injury. Only operate the motor at elevated frequencies after getting their approval. Otherwise, there is the danger of equipment damage. DO NOT power or operate the inverter if the jumper is removed. If parameter B exceeds the motor FLA rating, the motor may overheat and damaged. Parameter B, level of electronic thermal setting, is a variable parameter. So never touch the inverter power terminal even the motor is not running. Otherwise unexpected performances may occur.
While the inverter is energized, be sure not to open the front case. Be sure to stop the inverter before approaching the machine be sure to design the machine so that safety for personnel is secure even if it restarts.
If a restart may pose danger to personnel, so be sure to use a lock-out circuit so that it will not restart after power recovery. Be sure to enable the Stop Key separately from the emergency stop. Be sure to apply the alarm reset only after verifying the Run command is OFF.
Before turning power ON, confirm that the Run command is not active.
