CHAPTER 1 : SAFETY INSTRUCTIONS
WARNING! Ignoring the following instructions can cause physical injury or
damage to the equipment or death.
1.1 Pre-Installation Safety Measures
1. Before using the unit, read all instructions and cautionary markings
on the unit and all the sections of this manual.
2. The gross weight of the equipment is close to 20 Kg. Kindly lift the
USPC carefully to avoid any physical injury.
3. Please check the package for any sign of damage to ensure personal
safety. Don't use the damaged or incomplete USPC .
4. Customers are NOT authorized to open the USPC or to do any kind of
modification, or repair; otherwise, there is a danger of shock and loss
of warranty.
5. To store the USPC, kindly follow instructions given in Chapter 2
"INTRODUCTION".
1.2 Installation Safety Measures
1. Installation should be done in presence of a professional technician.
Safety equipment like safety shoes, helmets, and gloves should be
used by the technician. Only licensed person, who has been trained
in design, installation, commissioning, and operation of USPC is
permitted to operate this equipment.
2. To prevent risk of shock during installation and maintenance, please
make sure that all AC and DC terminals are plugged out.
3. Installation of the universal controller should be carried out on a
solar structure with proper ground clearance & specified nuts & bolts.
4. Install the USPC on metal or other non-flammable
material, and keep it away from any combustible material.
5. The USPC should not be installed inside a closed chamber. Ventilation
is required to ensure proper heat dissipation. Ignoring this will result
in malfunctioning of the unit and loss of warranty.
6. Before starting wiring and connections make sure that PV panels,
USPC , motor and all other accessories are properly fitted on their
designated place.
7. Ensure that the USPC, motor, and adjoining equipment are properly
earthed to reduce electromagnetic emission and interference.
8. Unit must be earthed using appropriate wire size diameter and its
diameter should be equal to or higher than that input power supply
wires (refer regional safety standard specific to your location).
9. Make sure that the voltage grade of the power supply is consistent
with the USPC 's voltage. Also, note that all PV panels are connected in
series or parallel as per system's requirement in order to have
required voltage fed to the drive.
10. There must not be any loose connection. Make sure that all
insulations are proper in order to prevent any damage/injury. Also
periodically inspect insulation in case of a bad weather.
11. Check whether the wiring is correct and firm, there should not be any
short circuit in the peripheral equipment's circuit.
12. Ensure that the output of the USPC is turned off while
setting all the required parameters.
13. Ensure that no unauthorized filter is connected to the output of the
USPC It may cause loss of warranty.
1.3 Safety during Operation
1. Make sure that the ratings of the pump, motor, PV panels, and
USPC comply with each other.
2. The heat sink should not be touched otherwise there is a danger of
getting burnt.
3. Do not operate or touch the USPC with the wet hand.
4. Do not put any of your belongings like mobile etc. on the USPC .
5. Disconnect PV power from the USPC under the
supervision or presence of a trained electrician.
6. Before opening the housing, the USPC must be disconnected from
PV.
7. After the input is disconnected from the USPC , wait for
at least five minutes so as to allow the internal capacitors to get
discharged for the safety of operation.
8. Ensure polarity, tightness and wire size are correct, before energizing
the USPC.
