Foreword

Thank you for purchasing and using SCOV SV800 series intelligent vector frequency inverter.

The SV800 series inverter is a kind of high-performance intelligent frequency inverter. We have

made great breakthrough in dynamic response, speed-stabilizing precision, torque precision,

intelligent start-up, weak magnetic control features and so on and made them reach international

top technology level. After combined with the application characteristics of some new industries,

the applicability and the industry design of the products are further strengthened, so it can better

meet the requirements of all kinds of transmission applications.

After careful study, SCOV found that if we want to achieve a breakthrough in the core

algorithm, we must systematically study the solution, especially perform algorithmically

accurate calculations for the nuances of the theoretical model of the motor and the actual motor

parameters, the nonlinear loss of the drive circuit and the loss of the connecting wire.

The practice has proved that the implementation of these methods has achieved a surprising

result and has reached even surpassed the level of international first-class brands on a number of

core indicators, which indicates that the era of truly cost-effective and high-performance

frequency inverter has arrived.

No professional parameter adjustment required, a high-performance drive can be realized only

after self-learning or auto-tuning , so we re-define SV800 series inverter as the intelligent vector

frequency inverter.

Born for intelligence, SCOV will work with you to move forward!

SV800/SV800A User Manual 1 Safety information and precautions

1 Safety information and precautions

1.1 Safety precautions

Users should familiar with the manual and other related technical materials and be sure to

follow the safety precautions required in this chapter when installing, operating, and

maintaining the product. At the same time, you should also know about the mechanical

knowledge, safety information, precautions and so on.

In the manual, safety precautions are classified into <Danger> and <Warning> two categories:

DANGER: Failure to comply with the notice will result in fire, serious injury or even

death.

WARNING: Failure to comply with the notice will result in personal injury or devices and

property damage, even accidents.

Both marks which used in the manual indicate that there is an important content of safety.

Failure to comply with those notices may lead to death, serious injury, damage to the products

and related machines and systems. SCOV will assume no liability or responsibility for any

injury, damage or loss caused by improper operation.

1.1.1 Safety precautions before installation

DANGER

To avoid damage expanding and injury, please don't install the frequency inverter if you find water

seepage, component missing or damaged.

Do not install it if the packing list not conform to the product.

WARNING

Do not touch the components with your hands. Electrostatic may cause damages.

The withstand voltage test has been done before leaving the factory. The users do not need to perform

the test on the inverter again. It may cause damage to the inverter insulation and internal components.

Do not use the product when the rated value in the nameplate is inconsistent with the order

requirements.

1.1.2 Safety precautions for transporting and installation

DANGER

Install the equipment longitudinally on incombustible objects such as metal, and keep it away from

combustible materials. Otherwise it may result in a fire.

Install the equipment in the place that can bear the weight to avoid danger of injury due to falling.

Do not install the equipment in an environment containing explosive gas. It may has danger of

explosion.

1 Safety information and precautions SV800/SV800A User Manual

WARNING

Lift and handle the inverter gently when carrying, do not hold the front cover with one hand only. It

may hurt your feet or damage the inverter if it falls off.

Prevent conductive objects such as screws and metal shavings from falling into the inverter during

installation. It may cause the inverter to malfunction or be damaged.

Avoid places with harsh environments such as oil mist, dust suspension, vibration, etc. When

installing in a cabinet, please ensure that the ambient temperature in the cabinet is within the allowed

temperature range of the inverter. Otherwise it may cause the inverter to malfunction or be damaged.

1.1.3 Safety precautions for wiring

DANGER

Do not perform wiring work expect for electrical construction professionals. Otherwise it has risk of

electric shock and fire.

Before wiring the inverter terminals, you must cut off all power connected to the inverter. The waiting

time after the power is cut off is not shorter than the time marked on the inverter. Also ensure the DC

voltage between +1 ~- or + 2 ~- is less than 30V. What's more, the inverter must properly regulate

the ground wire. Otherwise it has a danger of electric shock.

Please connect the input power cable and the motor cable correctly. Never connect the input power to

the output terminals (U, V, W) of the inverter. Pay attention to the marks on the terminals and do not

connect the wrong wires. Otherwise it has risk of damage to the inverter.

Never connect the braking resistor directly between the DC bus positive terminal +1 or +2 and the

negative terminal -. Otherwise it has risk of fire and damage to the inverter.

The main circuit terminal wiring screws must be tightened well. For the wire diameter, please refer to

the recommendations in this manual. Otherwise it has risk of fire and damage to the inverter.

It is forbidden to connect AC220V voltage level signals to terminals except for the control terminals

TA, TB, TC and MA, MB, and MG. Otherwise is has risk of damage to the inverter.

WARNING

Ensure that the rated voltage of the inverter is consistent with the voltage of the AC power supply.

Otherwise it may cause damage to the inverter.

The encoder signal line should uses shielded wire, and the single end of the shield layer should

reliably grounded. Otherwise it may cause the inverter to malfunction.

1.1.4 Safety precautions for debugging and operation

DANGER

Ensure the front cover installed well before connect the input power supply. After power-on, do not

open the cover and operate it as there is a high voltage inside. Otherwise it has a danger of electric

shock.

Please ensure the safety and reliability around the motor and mechanical load during motor electric

parameters auto-tuning and the inverter operation. Otherwise it has risk of injury.

Non-professional technicians are prohibited from testing signals during power-on. Otherwise it has

risk of electric shock and damage to the inverter.

Forbidden to repair the motor and mechanical equipment during power-on. Otherwise it has risk of

electric shock and personal injury.
