Essential information for avoiding safety hazards, product damage, and ensuring correct operation.
Warnings about severe electrical shock and burns from drive voltages, emphasizing extreme care.
Ensuring safe system design, installation, commissioning, and maintenance by trained personnel.
Voltages in AC supply, DC bus, output cables, and internal parts can cause severe shock.
AC supply must be disconnected using an approved isolation device before servicing.
Capacitors retain lethal voltage after supply disconnect; allow time for discharge.
Diagrams for power terminal connections for Size A and Sizes B, C, and D drives.
AC supply must have suitable overload and short circuit protection to prevent fire risk.
Adhere to terminal tightening torques for fire hazard prevention and UL listing validity.
Permanent fixed ground connection required for safety if EMC filter is installed.
Control circuits have basic insulation; ensure external circuits have supplementary insulation.
Protective cover for PCB connector provides safety; must be replaced or protected.
