Hoisting
With some large capacity drives, the transformer, rather than the transformer panel itself, must be hoisted directly. The
drive may deform or fall down if the drive panel frame is hoisted. For details, refer to the installation method described in
the instruction manual.
■
Radio Frequency Interference
Inputs and outputs of the drive (main circuit) contain harmonic components that may adversely affect communication
devices, such as AM radios, used in the vicinity. Use high-voltage cables and ground any shielded cables. Separate cables
for control from high-current circuits (main circuit and relay sequence circuits) to avoid induction from peripheral
devices. (It is advisable to separate them by a distance of 30 cm or more.)
■
Leakage Current
Harmonic leakage current passes through stray capacitance between the drive power lines, ground and the motor lines.
Consider taking measures against this leakage current.
