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
5
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
6
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.

3.3 Wiring
DANGER
1. Wiring of the inverter can be performed only by qualified professionals.
2. Before opening the cover board of the inverter, cut the power supply and wait
for at least five minutes after all indicators on the keypad go out.
3. The wiring inside the inverter can only begin after the internal high-voltage
indicator of the inverter goes out or the voltage between terminals DC＋and
DC- (measured with voltmeter) is less than 36V.
4. The inverter must be earthed reliably, otherwise there may be a risk of electric
shock or fire.
5．Shorting DC＋and DC- is prohibited. That may cause fire or damage to
properties.
6．Connecting the power line with U, V or W is prohibited.
7．The inverter has passed the voltage resistance test before it is shipped from the
factory; the users need not do this test again.
8. Major loop terminals and conductor cold-pressed terminal shall be firmly
connected. Attachment DC electric reactor shall be installed if power is over
90kW.
9. All terminals must be securely connected.
10. Connecting surge absorbing capacitors or voltage-dependent resistors on the
output side of the inverter is prohibited.
