1 Precautions

1.1 Safety precautions

I. Installation

 Do not install the inverter at a place with or near inflammable objects, otherwise there may be a

risk of fire.

 Install the inverter on flat, smooth and solid surface and keep it away from moist, heat and

condensation environment.

II. Wiring

 Make sure the high-voltage indicator is off and the DC link voltage is lower than 36V, otherwise

there may be a risk of electric shock.

 Make sure that the input power is completely cut off before the wiring is conducted, otherwise

there may be a risk of electric shock.

 Do not connect a braking resistor between the DC+ terminals DC- to avoid fire.

 The voltage of the input power terminals should not be out of the rated voltage range to avoid

damages to the inverter.

 The grounding terminal(PE) of the inverter must be securely connected to earth (resistance to

earth≤10), otherwise there may be a risk of electric fire.

III. Check before switching on the power

 Close the door of the inverter before turning on the power, otherwise there may be a risk of

electric shock or explosion.

 Before trying to run the motor at a frequency over the rated motor frequency, make sure that the

motor and the mechanical devices can endure such a high speed.

IV. Precautions on power and operation

 Check if parameters are appropriately set before commissioning.

 Do not open the front cover while the input power is switched on, for the high voltage inside

may cause electric shock.

 Do not handle the inverter with wet hands. That may lead to electric shock.

 “Power-on auto start”is enabled before shipment from the factory. When the terminal control

and the run signal are valid, the inverter will start automatically once the power is on.

 Do not control the run and stop of the inverter by switching on and off the input power.

 Related parameters should be reset after parameter initialization.

 If the function of restart has been set (such as auto-reset or restart after momentary power failure),

do not approach the motor or mechanical load while the inverter is waiting to restart.

V. Precautions on transport and package

 Do not place more inverters than specified in the packaging box.

 Do not put any heavy object on the inverter.

 Do not open the cover board during transportation.

 Do not apply any force on the keypad and the cover board while handling the inverter, otherwise

there may be a risk of injury to people or damage to equipment.

1 Precautions

VI. Disposal

 Dispose the inverter as industrial waste.

 The electrolytic capacitors inside the inverter may explode while burned.

 Plastic components of the inverter will generate poisonous gases while burned.

1.2 Other precautions

I. About motor and mechanical load

Comparison with commercial power operation

Hope800 inverter is a voltage-type PWM motor drive. Its output voltage contains some harmonics.

Compared with the commercial power, it creates more loss and noise and leads to largrer temperature rise of

the motor.

The insulation withstands voltage of the cables and motor should be taken into account when the input

voltage is high or the motor cables are long.

Constant-torque, low-speed operation

When a common motor runs at low speed for a long time, the motor temperature will rise due to the

weakened cooling effect. So if a motor is required to operate at low speed and constant torque for a long period

of time, an inverter or the forced air cooling method must be applied.

Overload protection

If the rated capacity of the motor does not match that of the inverter, regulate the overload protection level

or adopt other protective measures so that the motor can operate safely.

Running above 50Hz

If you plan to run the motor over 50Hz, be aware that the vibration and noise will increase and make sure

that the motor bearings and mechanical devices can withstand such a high speed.

Lubrication of mechanical devices

While running at low speed for a long time, such mechanical devices as gearbox and gears may be

damaged due to weakened lubricating effect. Before you run them, check the lubrication conditions.

Load of regulative torque

Regulative torque often occurs while a load is hoisted, and the inverter often stops due to overvoltage

protection. In this case, an appropriate braking unit should be installed.

Mechanical resonant point

Certain output frequencies of the inverter may be the mechanical resonant points. To avoid these points,

place anti-vibration rubber under the base of the motor or setting the jump frequencies.

Motor insulation check before connected to the inverter

When the motor is used for the first time or reused after it has not been used for a long time, the motor

insulation must be inspected to prevent the damage to the inverter caused by the failed insulation of the motor

windings. Use a 500V voltage-type megaohm meter to measure the insulation resistance, which should be no

less than 5MΩ.

II. About inverter

Capacitor or voltage-dependent resistor for power factor improvement

1 Precautions

As the inverter output is of PWM voltage type, the capacitor or voltage-dependent resistor (for improving

the power factor) installed on the output side of the inverter will lead to inverter trip or damage to

components. Do remove the capacitor or the voltage-dependent resistor before using the inverter.

Installation of switching devices (e.g. contactor) on inverter output side

If a switching device like contactor is required to be installed between the inverter and the motor, make

sure the on/off operation is performed while the inverter has no output, otherwise the inverter may be

destroyed.

Frequent start and stop

For applications where frequent start and stop are needed, terminals are recommended for the control of

the start/stop of the inverter. Using the switching device (such as contactor) on the inverter input side to start or

stop the inverter frequently is prohibited. That may destroy the inverter.

Using the inverter beyond the rated value

It is not recommended to operate the inverter beyond the range of the allowable input voltage. If the

inverter has to be used beyond the range, raise or reduce the voltage via a voltage regulator.

Lightning protection

With the built-in protection of overvoltage from lightning, the inverter has certain self-protection ability

against lightning strike.

Leakage protector

The high-speed switching operation during the running of the inverter will generate high-frequency

current which sometimes causes the mis-operation of the leakage protection circuit. To address this issue,

moderately lower the carrier frequency, shorten the wires or install a leakage protector.

Observe the following points while installing the leakage protector.

1) The leakage protector should be installed on the inverter input side, preferably behind the air switch

(non-fuse circuit breaker).

2) The leakage protector should be one that is insensitive to higher harmonics or specially designed for

the inverter (sensitivity above 30mA). If a common leakage protector is selected, its sensitivity and action time

should be greater than 200mA and 0.2s respectively.

Derating of inverter

1) If the ambient temperature exceeds 40℃, the inverter should be derated as per figure 1 and external

forced cooling should be provided.

2) If the altitude is above 1000 meters, heat dissipation effect of the inverter will be poor due to thin air

thus it should be derated, with derated output and input current value shown in figure B and C;

3) If the carrier frequency is greater than the factory setting, the inverter should be derated by 5% for

every 1kHz increase.
