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·

Inverter

 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.

 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.

Fig 1-4 Capacitors are prohibited to be used.

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 supply onto U,V,W or terminals.  Please do not install inverter directly under sunshine, do not block up the 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.

2.4 Parameters Setting

This inverter has numerous function parameters, user can modify to effect different modes of operation control. User needs to realize that if user sets password valid (F107=1), user‘s password must be entered firstly if parameters need to set after power off or protection is effected, i.e., to call F100 as per the mode in Table 2-2 and enter the correct code. User‘s password is invalid when leaving factory and user could set corresponding parameters without entering password.

3.4 Functions of control terminals

The key to operate the inverter is to operate the control terminals correctly and flexibly. The control terminals are not operated separately, and they should match corresponding settings of parameters. This chapter describes basic functions of the control terminals. The users may operate the control terminals by combining relevant contents hereafter about ―Defined Functions of the Terminals‖.

Wiring for digital input terminals:

Generally, shield cable is adopted and wiring distance should be as short as possible. When active signal is adopted, it is necessary to take filter measures to prevent power supply interference. Mode of contact control is recommended. Digital input terminals are only connected by common source electrode (NPN mode) or by common drain electrode (PNP mode). If NPN mode is adopted, please turn the toggle switch to the end of ―NPN‖. Wiring for control terminals as follows:

1. Wiring for positive source electrode (NPN mode).

2. Wiring for active source electrode(NPN mode)

3. Wiring for positive drain electrode (PNP mode)

4. Wiring for active drain electrode (PNP mode)

Wiring by source electrode is a mode in common use at present. As factory defaults of control terminals, wiring for control terminal is connected by source electrode, user should choose wiring mode according to requirement. Instructions of choosing NPN mode or PNP mode:

1. There is a toggle switch J7 near to control terminals. Please refer to Fig 3-5.

2. When turning J7 to ―NPN‖, DI terminal is connected to CM. When turning J7 to ―PNP‖, DI terminal is connected to 24V.

3.5 Measurement of main circuit(voltages, currents and powers)

Since the voltages and currents on the inverter power supply and output sides include high-frequency components, measurement data depends on the instruments used and circuits measured. When commercial frequency instruments are used for measurement, measure the following circuits(Fig3-6) with the recommended instruments(Table 3-3).
