WARNING
All DURApulse drives require a symmetrical 3-phase power source.
Do not connect them to grounded, center-tapped delta transformers of the type
typically used for lighting circuits.
WARNING: The AC drive may be destroyed beyond repair if incorrect cables are
connected to the input/output terminals. Never connect the AC drive output
terminals T1, T2, and T3 directly to the AC main circuit power supply.
WARNING: The mounting enclosure of the AC drive must comply with EN50178. Live
parts shall be arranged in enclosures or located behind barriers that meet at least the
requirements of the Protective Type IP20. The top surface of the enclosures or barrier
that is easily accessible shall meet at least the requirements of the Protective Type
IP40. Users must provide this environment for DURAPULSE Series AC Drive.
WARNING: Ground the DURAPULSE AC Drive using the ground terminal. The
grounding method must comply with the laws of the country where the AC drive is to
be installed. Refer to “Basic Wiring Diagram” in CHAPTER 2.
WARNING: A charge may still remain in the DC-link capacitor with hazardous
voltages, even if the power has been turned off. To avoid personal injury, do not
remove the cover of the AC drive until all "DISPLAY LED" lights on the digital keypad
are off. Please note that there are live components exposed within the AC drive. Do
not touch these live parts.
WARNING: There are highly sensitive MOS components on the printed circuit boards,
and these components are especially sensitive to static electricity. To avoid damage to
these components, do not touch these components or the circuit boards with metal
objects or your bare hands.
WARNING: AC input power must be disconnected before performing any maintenance.
Do not connect or disconnect wires or connectors while power is applied to the
circuit. Maintenance must be performed only by a qualified technician.
WARNING: Read this manual thoroughly before using DURAPULSE Series AC Motor Drives.
