1.7 Designed Standards for Implementation
IEC/EN 61800-5-1: 2007 Adjustable speed electrical power drive systems safety
requirements.
IEC/EN 61800-3: 2004/+A1: 2012 Adjustable speed electrical power drive systems-Part 3:
EMC product standard including specific test methods.
1.8 Safe Instructions and Precautions
Please check the model in the nameplate of the inverter and the rated value of the
inverter. Please do not use the damaged inverter in transit.
Installation and application environment should be free of rain, drips, steam, dust
and oily dirt; without corrosive or flammable gases or liquids, metal particles or
metal powder. Environment temperature within the scope of -10℃～+40℃.
Please install inverter away from combustibles.
Do not drop anything into the inverter.
The reliability of inverters relies heavily on the temperature. The around temperature
increases by 10℃, inverter life will be halved. Because of the wrong installation or
fixing, the temperature of inverter will increase and inverter will be damaged.
Inverter is installed in a control cabinet, and smooth ventilation should be ensured
and inverter should be installed vertically. If there are several inverters in one
cabinet, in order to ensure ventilation, please install inverters side by side. If it is
necessary to install several inverters up and down, please add heat-insulation plate.

EM30
·7·
Never touch the internal elements within 15 minutes after power off. Wait till it is
completely discharged.
Input terminals L1/R, L2/S and L3/T are connected to power supply of 400V/230V
(L1, L2 are connected to 230V) while output terminals U, V and W are connected to
motor.
Proper grounding should be ensured with grounding resistance not exceeding 4Ω;
separate grounding is required for motor and inverter. Grounding with series
connection is forbidden.
There should be separate wiring between control loop and power loop to avoid any
possible interference.
Signal line should not be too long(less than 3m) to avoid any increase with common
mode interference.
If circuit breaker or contactor needs to be connected between the drive and the motor,
be sure to operate these circuit breakers or contactor when the drive has no output,
to avoid damaging of drive.
Meet the environmental requirements of EM30 series technical specifications in
table 1-1.
Before using the drive, the insulation of the motors must be checked, especially, if it is
used for the first time or if it has been stored for a long time. This is to reduce the risk of
the drive from being damaged by the poor insulation of the motor.
Do not connect any varistor or capacitor to the output terminals of the drive, because the
drive‘s output voltage waveform is pulse wave, otherwise tripping or damaging of
components may occur; in addition, do not install circuit breaker or contactor at the
output side of the drive as shown in Fig 1-4.
Fig 1-4 Capacitors are prohibited to be used.
Derating must be considered when the drive is installed at high altitude, greater than
1000m. This is because the cooling effect of drive is deteriorated due to the thin air,
as shown in Fig. 1-5 that indicates the relationship between the elevation and rated
current of the drive.

EM30
·8·
Fig 1-5 Derating drive‘s output current with altitude
Never touch high-voltage terminals inside the inverter to avoid any electric shock.
Before inverter is powered on, please be sure that input voltage is correct.
Please do not connect input power supplyonto U,V,W or terminals.
Please do not install inverter directly under sunshine, do notblock upthe cooling hole.
All safety covers should be well fixed before inverter is power connected, to avoid
any electric shock.
Only professional personnel are allowed for any maintenance, checking or
replacement of parts.
No live-line work is allowed.
1.9 Examination and Maintenance
1.9.1 Periodic checking
Cooling fan and wind channel should be cleaned regularly to check whether it is
normal; remove the dust accumulated in the inverter on a regular basis.
Check inverter‘s input and output wiring and wiring terminals regularly and check if
wirings are ageing.
Check whether screws on each terminals are fastened.
Check whether inverter is corrosive.
1.9.2 Storage
Please put the inverter in the packing case of manufacture.
If inverter is stored for long time, please charge the inverter every half a year to
prevent the electrolytic capacitors damaged. The charging time should be longer
than 5 hours.
1.9.3 Daily Maintenance
Environment temperature, humidity, dust and vibration would decrease the life of inverter.
Daily maintenance is necessary to inverters.
Daily inspecting:
Inspecting for noise of motor when it is working.
Inspecting for abnormal vibration of motor when it is working.
Inspecting for the installing environment of inverter.
Inspecting for the fan and inverter temperature.
Daily cleaning:
Keep the inverter clean. Clean surface dust of inverter to prevent dust, metal powder,
oily dirt and water from dropping into the inverter.
