1. SAFETY
1.1. General Safety Information
This device should only be used in accordance o instructions within this manual and
in compliance with local, regional and national laws and regulations. Only allow this
device to be installed, operated, maintained, repaired by other persons who have also
read and understood this manual. Ensure the manual is included with this device
should it be passed to a third party.
DO NOT allow minors, untrained personnel, or person(s) suffering from a physical or
mental impairment that would affect their ability to follow this manual, install, maintain
or repair this device.
Any untrained personnel who might get near this device while it is in operation MUST
be informed that it is dangerous and instructed carefully on how to avoid injury.
1.2. Symbols
This symbol indicates information that if ignored, could result in personal
injury or even death due to incorrect handling.
This symbol indicates information that if ignored, could result in personal
injury or physical damage due to incorrect handling.
Indicates information that is considered important, but not hazard-related.

1.3. Safety Instructions
Be sure to read this manual thoroughly before installation.
Do not attempt to install the inverter by yourself. Installation work must be carried out
in compliance with national wiring standards and by suitably qualified personnel only.
Do not turn on the power until all installation work is complete.
Do not disassemble the inverter. If you need repair or maintenance, contact a
professional service centre.
Always use an individual power supply line protected by a circuit breaker and operating
on all wires with a distance between contacts of at least 3mm for this unit.
The unit must be correctly grounded and the supply line must be equipped with a
suitable breaker and RCD to protect people.
Disconnect all wires/cables before performing any maintenance or cleaning to reduce
the risk of electrical shock.
The unit is not explosion-proof, so it should not be installed in an explosive
atmosphere.
Never touch electrical components immediately after the power supply has been
turned off since the system can still have residual energy, so electric shock may occur.
Therefore, after turning off the power, always wait 5 minutes before touching electrical
components.
This unit contains no user-serviceable parts. Always consult an authorised contractor
for repairs.
1.4. Disposal Remarks
DO NOT dispose this product with domestic waste!
Electrical devices should be disposed of in accordance with regional directives on
electronic and/ or electronic-waste disposal. In case of further questions, please consult
your supplier. In some cases, the supplier can take care of proper disposal.
HIGH LIFE RISK DUE TO FIRE OR ELECTROCUTION.
The Sunsynk Single-Phase Hybrid Inverter can only be installed by a qualified
licensed electrical contractor. This is not a DIY product.
