Qualification
of skilled person
This grid-tied inverter system operates only when properly connected to the AC -distribution network.
Before connecting the SP Series to the power distribution grid, contact the local power distribution grid
company. This connection must be made only by qualified technical personnel to connect, and only
after receiving appropriate approvals, as required by the local authority having jurisdiction.
2.3
Safety instruction
The SP Series Inverters is designed and tested according to international safety requirements; however,
certain safety precautions must be observed when installing and operating this inverter. Read and follow
all instructions, cautions and warnings in this installation manual. Any questions, please contact the
supplier .
2.4
Assembly Warnings
warning
Before installation, inspect the unit to ensure absence of any transport or handling
damage, which could affect insulation integrity or safety clearances; otherwise it
could result in safety hazards.
Assemble each inverter the instructions in this manual. Be Careful when choosing
installation location and according to specified cooling requirements. Unauthorized
remove the necessary protections, improper use, incorrect installation and operation
may result the serious safety and shock hazards or equipment damage.
In order to minimize the potential of a shock hazard due to hazardous voltages, cover
the entire solar array with dark material prior to connecting the array to any
equipment.
caution
Grounding the PV modules:The SP Series is a high frequency inverter(without
transformer). That is why it has no galvanic separation. Do not ground the DC circuits
of the PV modules when connected to the SP Series. Only ground the mounting frame
of the PV modules.If you connect grounded PV modules to the SP Series, that will
show error message "PV ISO Low".
Follow the local requirements for grounding the PV modules and the PV generator.
We recommend connecting the generator frame and other electrically conductive
surfaces in a manner which ensures continuous conduction with ground in order to
have optimal protection of the system and personnel.
2.5
Electrical Connection Warnings
The components in the inverter are mobilizable. Touching mobilizable
components can result in serious injury or death.
Do not open the
inverter except the wire box by qualified persons.
Electrical installation, repairs and conversions may only be carried out by
electrically qualified persons.
Do not touch damaged inverter.
Danger to life due to high voltages in the inverter.
There has residual voltage in the inverter. The inverter takes 20 minutes to
discharge.
Wait 20 minutes before you open the wire box.
Persons with limited physical or mental abilities may only work with the SP Series
inverter following proper instruction and under constant supervision. Children are
forbidden to play with the SP Series inverter. Must keep the SP Series inverter away
from children.
