WAARSKUWING: Gevaar van elektriese skok. Installasie en onderhoud moet slegs deur gekwalifiseerde personeel uitgevoer word.

• Always disconnect power before installation, wiring, or maintenance.
• Ensure proper grounding of the unit and connected equipment.
• Moenie die VFD met beskadigde kabels of as die omhulsel oop is, gebruik nie.
• Protect the unit from moisture, dust, and corrosive environments.
• Observe all local and national electrical codes.
• The VFD may have residual voltage even after power is disconnected. Wait at least 5 minutes after power-off before touching internal components.

5. Opstelling en installering

5.1 Montering

Mount the VFD in a clean, dry, and well-ventilated area. Ensure adequate clearance around the unit for heat dissipation. The compact size (142 x 110 x 85mm) allows for flexible installation.

5.2 Bedrading

Refer to the terminal block diagrams for correct wiring connections. Ensure all connections are secure and properly insulated.

7. Onderhoud

Gereelde onderhoud verseker die lang lewensduur en betroubare werking van u VFD.

• Skoonmaak: Periodically clean the VFD's exterior and ventilation grilles to prevent dust accumulation, which can impede cooling. Use a soft, dry cloth. Do not use liquid cleaners.
• Inspeksie: Inspekteer gereeld alle bedradingsverbindings vir styfheid en tekens van slytasie of skade. Kontroleer vir enige ongewone geluide of reuke tydens werking.
• Omgewingstoestande: Verseker dat die bedryfsomgewing binne die gespesifiseerde temperatuur- en humiditeitsreekse bly.
• Kapasitor Lewe: Electrolytic capacitors have a finite lifespan. If the VFD is in continuous operation for many years, consider professional inspection or replacement of capacitors.

Always disconnect power and wait for the discharge period before performing any maintenance.
