1.2 About Motor and Load
Compared to the industrial frequency running
The HD31 series inverters are voltage-type frequency inverters and their output is PWM wave with
certain harmonic wave. Therefore, the temperature, noise and vibration of the motor will be a little
higher than that at industrial frequency running.
Constant torque at low-speed running
When HD31 drives a standard motor at low-speed running for a long time, the output torque ratings
will become worse due to the motor cooling is less effective. In that case, we suggest that you should
choose variable frequency motor.
Thermal protection of motor
When choose the adaptive motor, HD31 can effectively implement thermal protection of motor.
Otherwise it must adjust the motor protection parameters or other protection measures to ensure that
the motor is at a safe and reliable running.
Running above the rated frequency of motor
If the motor runs exceeding its rated frequency, the noise will increase. Pay attention to the motor
vibration as well as ensure the motor bearings and mechanical devices to meet the requirement of
running speed range.
Lubrication of mechanical devices
At long time low-speed running, provide periodical lubrication maintenance for the mechanical
devices such as gear box and geared motor etc. to make sure the drive results meet the site need.

HD31 Series User Manual V1.1 ―1―
Chapter 1 Safety Information and Precautions Shenzhen Hpmont Technology Co., Ltd.
Mechanical resonance point of load
Set the skip frequency (F05.17 - F05.19) to avoid the load device or the motor mechanical resonance
point.
Start and stop HD31
User should use the control terminal to start and stop HD31.
It is strictly forbidden to use contactor or other switches on the input side of HD31 to start and stop
directly, or it will damage the device.
Check the insulation of the motor
For the first time using of the motor or after long time storage, it needs checking the insulation of the
motor. Worse insulation can cause damage to HD31.
Note:
Use a 500V Mega-Ohm-Meter to test and the insulation resistance must be higher than 5Mohm.
Load and negative torque
For the occasion to boost load and the like, negative torque often occurs. Consider setting proper
parameters of the braking unit if HD31 is prone to overcurrent or overvoltage fault trip.
Requirement for leakage current protector RCD
Since the device generates high leakage current which goes through the protective grounding
conductor, please install B type leakage current protector RCD on one side of the power supply.
For the selection of RCD, users need to consider the possible problems of ground leakage current in
both transient status and steady status at start and during running. It is recommended to choose
either special RCD that can suppress the higher harmonics, or general RCD that has more aftercurrent.
Warning for ground mass leakage current
The device generates mass leakage current, so users need to confirm the reliable grounding before
connect to the power supply. The grounding should comply with the local relative IEC standard.
1.3 About HD31
No capacitor or varistor on the output side
Since HD31 output is PWM wave, it is strictly forbidden to connect capacitor for improving the power
factor or varistor for lightning protection to the output terminals so as to avoid HD31 fault trip or
component damage.
Contactors and circuit breakers connected to the output of HD31
If circuit breaker or contactor needs to be connected between HD31 and the motor, be sure to operate
these circuit breakers or contactor when HD31 has no output, so as to avoid any damage to HD31.
Running voltage
HD31 is prohibited to be used beyond the specified range of running voltage. If needed, please use
suitable voltage regulation device to change the voltage.
―2― HD31 Series User Manual V1.1
Shenzhen Hpmont Technology Co., Ltd. Chapter 1 Safety Information and Precautions
Capacitor energy storage
When the AC power supply is cut off, capacitor of HD31 sustains deadly power for a while. So to
disassemble HD31 that is powered, please cut off the AC power supply for more than 10 minutes,
confirm the internal charge indicator is off and the voltage between (+) and (-) of the main circuit
terminals is below 36V.
Generally, the internal circuit enables the capacitor to discharge. However, the discharging may fail in
some exceptions. In these cases, users need to consult Hpmont or our regional distributor.
Lightning surge protection
HD31 internal design has lightning surge overcurrent protection circuit, and has certain self-protection
capacity against the lightning.
Altitude and derating
In area where altitude exceeds 1000 meters, HD31 should be derating since the heatsink efficiency will
be reduced because of the tenuous air.
The rated value of output current derates by 1% for each 100m increase of the altitude. I.e. for the
altitude of 4000m, derated rate is 30% for rated current of HD31. Figure 1–1 is the derating curve of
rated current and the altitude.

• You can’t open the inverter cover to do wiring operation until the power is cut-off 10 minutes later. Do not wire or
detach the inverter internal devices at power-on situation.
• Do not do wiring operation until the internal charge indicator of the inverter is off and the voltage between (+)
and (-) of the main circuit terminals is below 36V.
• Check the wiring carefully before connecting emergency stop or safety circuit.
• The earth terminal PE of the inverters must be reliable earthing. It must use t wo separate earth wire due to the
leakage current from the inverter to ground.
• It must use Type B mode when utilize earth leakage protection devices(ELCB/RCD).
• Do not touch the wire terminals of the inverter when it is live. The main circuit terminals is neither allowed
connecting to the enclosure nor short-circuiting.
• Do not do dielectric strength test on the inverter.
• Do wiring connection of the braking resistor or the braking unit according to the wiring figure.
• Make sure the terminals are fixed tightly.
• Do not connect the AC supply cable to the output terminals U, V, W of the inverter.
• Do not connect the phase-shifting capacitors to the output circuit.
• Be sure the inverter has ceased output before switching motor or change-over switches.
• The inverter DC bus terminals must not be short-circuited.

4.2 Peripheral Accessories Selection
4.2.1 Wiring specifications of input and output
The AC supply to HD31 must be installed with suitable protection against overload and short-circuits,
i.e. MCCB (molded case circuit breaker) or equivalent device.
The recommended specification of MCCB, contactor & cables are shown as Table 4-2.
The size of ground wire should accord with the requirement in 4.3.5.4 of IEC61800-5-1, as shown in
Table 4-1.

During trial running, make sure HD31 runs forward when the forward command is enabled.
If not, switch any two of the output terminals (U/V/W) or modify parameter F00.17 to change the
motor direction.
The supply and motor connection are shown as Figure 4–1.

4.4 Control Board and I/O Board
Danger
arning
• The control circuit is basically isolated with the power circuit. Do not touch HD31 after it is powered.
• If the control circuit is connected to the external devices with live touchable port, it should increase an additional
isolating barrier to ensure that classification of external devices not be changed
• If connect the communication terminal of the control circuit to the PC, choose RS485/232 isolating converter
which meets the safety requirement.
• Only connect the relay terminal to AC 220V voltage signal. Other control terminal are strictly forbiden for this
connection.
HD31 includes control board and I/O board, as shown in Figure 4–2.
