1. SAFETY PRECAUTIONS
The AC Drive is a power electronic device. For safety reasons, please read carefully those
paragraphs with "WARNING" and "CAUTION" symbols. They are important safety precau-
tions to be aware of while transporting, installating, operating or examining the AC drive.
Please follow these precautions to ensure your safety.
WARNING Personal injury may occur from improper operation.
CAUTION The AC Drive or mechanical system may be damaged by improper
operation.
WARNING
●
Do not touch the PCB or components on the PCB after turning off the power before
the charging indicator is turned off.
●
Do not attempt to wire circuitry while power is on. Do not attempt to examine compo-
nents and signals on the PCB while the drive is operating.
●
Do not attempt to disassemble or modify internal circuitry, wiring, or components of the
controller.
●
The grounding terminal of the controller must be grounded properly to 200V class type
III standard.
●
This is a product of the restricted sales distribution class according to EN61800-3.
In a domestic environment, this product may cause radio interference in which case the
user may be required to take adequate measures.
CAUTION
●
Do not attempt to perform dielectric strength test to internal controller components.
There are sensitive semiconductor devices vulnerable to high voltage in the controller.
●
Do not connect the output terminals: T1 (U), T2 (V), and T3 (W) to AC power.
●
The CMOS IC on the primary PCB of the controller is vulnerable to static electrical
charges. Do not contact the primary PCB of the controller.
