1 Notes on this Manual
General Notes
The KSY series is a transformerless solar inverter with indenpendent MPP tracker.
It converts the direct current (DC) from a photovoltaic (PV) array to grid-compliant
altent (AC) and feeds it into the ulity grid.

Danger to life due to high voltages of the PV array
When exposed to sunlight, the PV array generates dangerous DC voltage
which is present in the DC conductors and the live components of the
inverter. Touching the DC conductors or the live components can lead to
lethal electric shocks. If you disconnect the DC connectors from the inverter
under load, an electric arc may occur leading to electric shock and burns.
• Do not touch non-insulated cable ends.
• Do not touch the DC conductors.
• Do not touch any live components of the inverter.
• Have the inverter mounted, installed, commissioned and maintained only
by qualied persons with the appropriate skills.
• Prior to performing any work on the inverter, disconnect it from all voltage
sources as described in this document then wait 5 minutes at least.
Risk of injury due to electric shock and re caused by high leakage current
• The inverter must be reliably grounded in order to protect property and
personal safety.
Risk of injury due to hot heat sink
• The heat sink may get hot during operon. Do not touch!

Possible damage to health as a result of the eects of electromagnetic
radiation
• Please maintain a distance of at least 20cm from the inverter when it is in

Grounding the PV array
• Comply with local regons for grounding the PV array. We suggest the
frames of PV modules must be reliably grounded.
• Do not ground any of the terminals of the strings.
Damage to the seal of the cover in sub-zero conditions
• If you open the cover in sub-zero condion,the sealing of the cover can be
damaged.This can lead moisture entering the inverter.
• Do not open the cover at ambient temperatures lower than -5 .
• If a layer of ice has formed on the seal of the cover in sub-zero
comdions,remove it prior to opening the inverter(e.g. by mel the ice
with warm air). Observe the applicable safety regulaon.

10
Damage to the inverter due to electrostatic discharge
•Touching electronic components can cause damage to or destroy the
inverter through electrostac discharge.
• Ground yourself before touching any component.

4 Mounting
4.1 Ambien
1. Be sure the inverter is installed out of the reach of children.
2. Mount the inverter in areas where it cannot be touched inadvertently.
3. Ensure good access to the inverter for installaon and possible service.
4. To make sure that heat can dissipate, observe the following minimum clearance to
walls, other inverters, or objects:
C
5. The ambient temperature should be below 40°C to ensure opmal operaon.
6. Recommend to mount the inverter under the shaded site of the building or mount an
awning above the inverter.
7. Avoid exposing the inverter to direct sunlight, rain and snow to ensure opmal
operaon and extend service life.
8. The mounng method, locaon and surface must be suitable for the inverter's weight
and dimensions.

9. If mounted in a residenal area, we recommend mounng the inverter on a solid
surface. Plasterboard and similar materials are not recommended due to audible
vibraons when in use.
10. Do not put any objects on the inverter.
11. Do not cover the inverter.
