Solar Power and Irrigation

For the purpose of this manual and the product the following symbols are used.

Overview:

The system operates on power generated using solar PV (photovoltaic) system. The

photovoltaic array converts the solar energy into electricity, which is used for running

the motor pump set. The pumping system draws water from the open well, bore well,

stream, pond, canal etc.

The system requires a shadow-free area for installation of the Solar Panel.

Of all the ways solar electricity benefits the people on Earth, none makes as much

difference in the daily lives as pumping water. By providing water for irrigation or

potable water have obvious benefits for people in rural areas and especially for those

in developing nations. The proper choice is determined by application specific factors

like how much water is required and whether the water should be available at night

or just during high sun hours.

Solar Power and Irrigation:

 Irrigation is best utilisation of Solar power

 Usually area which require more water have high solar irradiation

 During summer time when more water is require, there is more sun light

 Water need not be available at night

 Maintenance facilities are lacking, Solar pump run maintenance free.

 Solar tracking can use.

 Definitions and Symbols

 HAZARDOUS HIGH VOLTAGE: Motor control equipment and electronic

controllers are connected to hazardous line voltages. When servicing drives and

electronic controllers, there may be exposed components with housing or protrusions at

or above line potential. Extreme care should be taken to protect against shock. Stand on

an insulating pad and make it a habit to use only one hand when checking components.

Always work with another person in case an emergency occurs. Disconnect power before

checking controllers or performing maintenance. Be sure equipment is properly

grounded. Wear safety glasses whenever working on electronic controllers or rotating

machinery.

 WARNING: This equipment should be installed, adjusted, and serviced by qualified

electrical maintenance personnel familiar with the construction and operation of the

equipment and the hazards involved. Failure to observe this precaution could result in

bodily injury.

 WARNING: For equipment protection, install a ground leakage type breaker with a

fast response circuit capable of handling large currents. The ground fault protection

circuit is not designed to protect against personal injury.

 WARNING: HAZARDOUS OF ELECTRICAL SHOCK. DISCONNECT INCOMING

POWER BEFORE WORKING ON THIS CONTROL.

 WARNING: Wait at least five (5) minutes after turning OFF the input power supply

before performing maintenance or an inspection. Otherwise, there is the danger of

electric shock.

 CAUTION: Proper grounds, disconnecting devices and other safety devices and

their location are the responsibility of the user and are not provided by Hitachi Industrial

Equipment Systems Co., Ltd.

 HIGH VOLTAGE: Dangerous voltage exists until power light is OFF. Wait at least

five (5) minutes after input power is disconnected before performing maintenance

Ii

 WARNING: This equipment has high leakage current and must be permanently

(fixed) hard-wire to earth ground via two independent cables.

 WARNING: Rotating shafts and above-ground electrical potentials can be

hazardous. Therefore, it is strongly recommended that all electrical work conform to

the National Electrical Codes and local regulations. Installation, alignment and

maintenance should be performed only by qualified personnel.

 CAUTION:



 b) Any motor used must be of a suitable rating.

 c) Motors may have hazardous moving path. In this event suitable protection must be

provided.

 CAUTION: Hazardous (main) terminals for any interconnection (motor, contact

breaker, filter, etc.) must be inaccessible in the final installation.

 CAUTION: This equipment should be installed in IP54 or equivalent enclosure.

 CAUTION: Connection to field wiring terminals must be reliably fixed having

two independent means of mechanical support. Use a termination with cable support

(figure below), or strain relief, cable clamp, etc.

Ii

 General Warnings and Cautions

 WARNING: Never modify the unit. Otherwise, there is a danger of electric shock and/or injury.

 CAUTION: Withstand voltage test and insulation resistance tests (HIPOT) are executed before

the units are shipped, so there is no need to conduct these tests before operation.

 CAUTION: Do not attach or remove wiring or connectors when power is applied. Also, do not

check signals during operation.

 CAUTION: Be sure to connect the grounding terminal to earth ground.

 CAUTION: When inspecting the unit, be sure to wait five minutes after turning OFF the power

supply before opening the cover.

 UL Cautions, Warnings and Instructions

 Warnings and Cautions for Troubleshooting and Maintenance The warnings and instructions in

this section summarizes the procedures necessary to ensure an inverter installation complies with

delines.

 Mounting location

Hardware installation

Study the following caution messages associated with mounting the inverter. This is the

time when mistakes are most likely to occur that will result in expensive rework, equipment

damage, or personal injury.

CAUTION: Be sure to install the unit on flame-resistant material such as steel plate.

Otherwise, there is the danger of fire.

CAUTION: Be sure not to place any flammable materials near the inverter.

Otherwise, there is the danger of fire.

CAUTION: Be sure not to let the foreign matter enter vent openings in the inverter

housing, such as wire clippings, spatter from welding, metal shavings, dust, etc. Otherwise,

there is the danger of fire.

CAUTION: Be sure to install the inverter in a place that can bear the weight according

to the specifications in the text. Otherwise, it may fall and cause injury to personnel.

CAUTION: Be sure to install the unit on a perpendicular wall that is not subject to

vibration. Otherwise, it may fall and cause injury to personnel.

CAUTION: Be sure not to install or operate an inverter that is damaged or has

missing parts. Otherwise, it may cause injury to personnel.

CAUTION: Be sure to install the inverter in a well-ventilated room that does not have

direct exposure to sunlight, a tendency for high temperature, high humidity or dew

condensation, high levels of dust, corrosive gas, explosive gas, inflammable gas, grinding-

fluid mist, salt damage, etc. Otherwise, there is the danger of fire.

Ensure Adequate Ventilation

To summarize the caution messages – you will need to find a solid, non-flammable, vertical

surface that is in a relatively clean and dry environment. In order to ensure enough room

for air circulation around the inverter to aid in cooling, it is recommended to maintain the

specified clearance and the inverter specified in the below diagram.

CAUTION: Be sure to maintain the specified clearance area around the inverter and

to provide adequate ventilation. Otherwise, the inverter may overheat and cause equipment

damage or fire.

provide adequate ventilation. Otherwise, the inverter may overheat and cause equipment

damage or fire.

 Electrical Wiring

You will connect wiring to the input of the inverter. First, you must determine whether the

inverter model you have required three-phase power only, or single-phase power only. All

models have the same power connection terminals [R/L1], [S/L2], and [T/L3]. So you must

refer to the specifications label (on the side of the inverter) for the acceptable power

source types! For inverters that can accept single-phase power and are connected that

way, terminal [S/L2] will remain unconnected. Note the use of ring lug connectors for a

secure connection.
