Apply rated torques to the terminal screws.

Under-torqued screws may allow connections to come loose while over-torqued screws may damage the terminals.

Risk of short circuit. Risk of drive malfunction.

Wiring must be performed by authorized, qualified personnel.

Risk of personal injury or death. Risk of damage to equipment.

A circuit-breaker must be installed between the Clean Power VFD and the mains.

Risk of personal injury or death. Risk of fire. Risk of damage to equipment

Make sure the input power supply has been completely disconnected before wiring.

Risk of personal injury or death. Risk of damage to equipment

Since the overall leakage current of this equipment SDB 1 2 185 may be up to 45 mA, ensure that the Clean Power VFD and it's associated motor have a proper ground connection compliant with local regulations.

Risk of personal injury or death.

Ensure that grounding wires meet the technical standards for electrical equipment. Impedance must conform with national and local regulations, safety regulation and/or electrical codes

Furthermore, ensure that the length of grounding wires are minimized.

connections should be periodically checked.

Improper grounding of equipment may lead to dangerous electrical potentials on the equipment chassis.

Risk of serious injury or death.

For power terminal wiring use only 600V 75℃ rated copper wire with the cable dimension specified in this document.

For control terminal wiring use only 600 V 75℃ rated copper wire with the cable dimension specified in this document.

Risk of overheating or fire.

Never connect the input line power cables to the output terminals (U/T1,V/T2,W/T3) of the AC drive.

Pay attention to the marks of the wiring terminals and ensure correct wiring.

Risk of damage to equipment.

Ensure that the input phase wiring sequence (R/L1, S/L3, T/L3)) is identical to the output phase sequence (U/T1,V/T2,W/T3.

Failure to do so may cause the motor to rotate in the opposite direction.

Risk of damage to equipment.

The ground loop impedance must conform to the requirements of local safety regulations.

The Clean Power VFD must be grounded by a connection capable of carrying the prospective fault current until the protective device (fuse, etc.) disconnects the AC supply.

The ground connections must be inspected and tested at appropriate intervals.

Do not connect power to the Clean Power VFD until the installation has been fully completed and the Clean Power VFD is ready to be operated.

Failure to do so may cause an electrical shock and result in personal injury or even death.

The AC supply to the Clean Power VFD must be installed with fuses to provide protection against overloads and short-circuits.

Nominal fuse ratings are shown in this document.

Failure to install properly rated fuses may result in fire.

Lock out and tag out all potential energy sources before working on the Clean Power VFD.

Do not share the ground wire with other devices, such as welding machines or electrical equipment using high current.

Improper equipment grounding may cause the VFD to malfunction due to electrical interference.

Risk of equipment malfunction.

When using multiple Clean Power VFD, ground each drive according to instructions.

Do not share a common ground between devices.

Improper grounding of equipment could result in abnormal operation of the drive.

Risk of equipment malfunction.

Ensure that input and output power cables are kept remote from the control cables in order to avoid interference with the latter.

If this is not possible, ensure that all crossovers occur at a right angle in order to minimize signal noise interference.

Risk of equipment malfunction.

Do not start or stop the Clean Power VFD with a magnetic contactor.

Risk of damage to equipment.

High levels of current drawn during power-on can affect the system.

Ensure that correctly rated circuit breakers are installed to operate safely during power-on.

Risk of nuisance breaker trip.

High impulse voltages, like lightning, may cause damage to the VFD.

While SmartD drives have built-in surge protection, they do not have sufficient protection to mitigate a lightning strike or similar high-energy event.

SmartD recommends the use of specialized surge protectors in areas prone to frequent lightning strikes.

Always mount the VFD before carrying out wiring connections.

Moving or mounting the VFD when wires are already connected may damage the wires and/or terminals, loosen the terminal connections or cause complete cable disconnection.

Do not connect more than one wire to a terminal position when wiring the power.

The power supply must be connected to the R/L1, S/L2, and T/L3 terminals.

Connecting them to the U/T1, V/T2, W/T3 terminals will damage the Clean Power VFD.

Shielded cables must be used for control terminal wiring.

Failure to do so may cause malfunction due to interference.

When grounding is needed, use shielded twisted pair cables.
