1 Introduction
1.1.1 Safety
Rotating shafts and electrical equipment can be hazardous. Therefore, it is strongly recommended that all electrical work conform to National
Electrical Code (NEC) and all local regulations. Installation, start-up and maintenance should be performed only by qualified personnel.
Factory recommended procedures, included in this manual, should be followed. Always disconnect electrical power before working on the unit. Although shaft
couplings or belt drives are generally not furnished by the manufacturer, rotating shafts, couplings and belts must be protected with securely mounted metal
guards that are of sufficient thickness to provide protection against flying particles such as keys, bolts and coupling parts. Even when the motor is stopped, it
should be considered “alive” as long as its controller is energized. Automatic circuits may start the motor at any time. Keep hands away from the output shaft
until the motor has completely stopped and power is disconnected from the controller.
Motor control equipment and electronic controls are connected to hazardous line voltages. When servicing drives and electronic controls, there will be exposed
components 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 of an emergency. Disconnect power whenever possible to check controls or to
perform maintenance. Be sure equipment is properly grounded. Wear safety glasses whenever working on electric control or rotating equipment.
Safety Guidelines
1. The drive must be disconnected from the AC line before any service work is done.
2. The “Stop/Off” key on the Keypad of the drive does not disconnect the equipment from the AC line and is not to be used as a safety switch.
3. Correct protective grounding of the equipment must be established. The user must be protected against supply voltage and the motor must be protected
against overload in accordance with applicable national and local regulations.
4. Ground currents are higher than 3 mA.
Warning against Unintended Start
1. While the drive is connected to the AC line, the motor can be brought to a stop by means of external switch closures, serial bus commands or references.
If personal safety considerations make it necessary to ensure that no unintended start occurs, these stops are not sufficient.
2. During programming of parameters, the motor may start. Be certain that no one is in the area of the motor or driven equipment when changing
parameters.
3. A motor that has been stopped may start unexpectedly if faults occur in the electronics of the drive, or if an overload, a fault in the supply AC line or a
fault in the motor connection or other fault clears.
4. If the “Local/Hand” key is activated, the motor can only be brought to a stop by means of the “Stop/Off” key or an external safety interlock
NB!
It is responsibility of user or person installing drive to provide proper grounding and branch circuit protection for incoming power and motor overload according
to National Electrical Code (NEC) and local codes.
Electronic Thermal Overload in UL listed drives provides Class 20 motor overload protection in accordance with NEC in single motor applications, when par.
F-10 Electronic Overload is set for Electronic Thermal Overload TRIP 1, Electronic Thermal Overload TRIP 2, Electronic Thermal Overload TRIP 3, or Electronic
Thermal Overload TRIP 4, and par. P-03 Motor Current is set for rated motor (nameplate) current.
1.1.2 Caution
Caution
The frequency converter DC link capacitors remain charged after power has been disconnected. To avoid an electrical shock hazard, disconnect the frequency
converter from the mains before carrying out maintenance. Wait at least as follows before doing service on the frequency converter:
