The information in this manual is subject to change without notice.
Throughout this manual, the following notes are used to alert you to safety considerations:
ATTENTION: Identifies information about practices or circumstances that can lead to personal
injury or death, property damage, or economic loss.
!
Important: Identifies information that is critical for successful application and understanding of the product.
The thick black bar shown on the outside margin of this page will be used throughout this instruction manual to
signify new or revised text or figures.
ATTENTION: The SP120 AC drive contains high voltage DC bus capacitors which take time to
discharge after removal of input power. Before working on the drive, wait five minutes for capacitors to
!
discharge to safe voltage levels. Darkened display LEDs are not an indication that capacitors have
discharged to safe voltage levels. Failure to observe this precaution could result in severe bodily injury
or loss of life.
ATTENTION: This drive generates dangerous electrical voltages and controls potentially dangerous
rotating mechanical parts. Disregarding the guidelines provided in this manual may result in severe
bodily injury or loss of life.
ATTENTION: Only personnel familiar with the drive and associated machinery should plan or
implement the installation, start-up and subsequent maintenance of the system. Failure to comply may
result in bodily injury and/or damage to the equipment.
ATTENTION: This drive contains ESD (Electrostatic Discharge) sensitive parts and assemblies. Static
control precautions are required when installing, testing, servicing or repairing this assembly.
Component damage may result if ESD control procedures are not followed. Failure to observe this
precaution could result in damage to the equipment.
ATTENTION: The drive is intended to be installed with a fixed ground connection. The protective
ground only offers protection for the drive, not against personal injury. According to EN 50178, it is not
recommended to use the SP120 drive on protective fault current switches as, due to a possible DC
component (rectifier load), the sensitivity of the safety switch will be reduced in the event of a failure.
If unavoidable, only type B RCDs should be used. As a precautionary measure, the EN 50178
regulations should be observed. Failure to observe this precaution could result in severe bodily injury
or loss of life.
ATTENTION: An incorrectly applied or installed drive can result in component damage or reduction
in product life. Wiring or application errors such as undersizing the motor, supplying an incorrect or an
inadequate AC supply, or excessive ambient temperatures may result in system malfunction. Failure
to observe this precaution could result in damage to the equipment.
ATTENTION: To prevent any injuries or damage, do not touch any components located within the
housing – either with your hands or with any other objects – if input voltage is applied or if the DC bus
capacitors are not discharged. Do not carry out any work on the wiring or check any signals if input
voltage is applied.
ATTENTION: Ensure that the input voltage corresponds to the voltage indicated on the product
nameplate. Environmental influences such as high temperatures and high relative humidity are to be
avoided as well as dust, dirt, and corrosive gases. The mounting location should be well ventilated and
not exposed to direct sunlight. Install the device upright on a non-flammable, vertical wall. Failure to
observe this precaution could result in damage to the equipment.
ATTENTION: The drive start/stop and enable control circuitry includes solid-state components. If
hazards due to accidental contact with moving machninery or unintentiojnal flow of liquid, gas, or solids
exist, an additional hardwired stop circuit is required to remove AC input power to the drive. Failure to
observe this precaution could result in severe bodily injury or loss of life.
ATTENTION: All the pertinent safety regulations, e.g. accident prevention regulations, professional
association regulations, EN, VDE regulations etc., must be observed. As these regulations are
implemented differently in different countries, the user must observe the regulations that apply for his
particular country. Failure to observe this precaution could result in severe bodily injury or loss of life.
