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.
