Warranty on products in the SUNSYS B series
Sicon S.r.l., which is part of the SOCOMEC group with registered headquarters at Via Sila 1/3 – Z. I. Scovizze, 36033 Isola Vicentina
(Vicenza), guarantees that itsSUNSYS B series products are compliant with technical specifications and applicable quality standards.
1) Conditions of Warranty
Sicon S.r.l. guaranteesSUNSYS B series products for a period of 5 years following purchase for manufacturing or material defects only.
The warranty commences on the date the new product was purchased by the end user at the showroom of an official dealer
(date as shown on the receipt).
This warranty applies only to products installed in Italy.
The warranty covers:
a) the repair or replacement of the defective product or component free of charge, whereas the cost of installing the replacement
product or component is the responsibility of the customer or end user;
b) the shipment of the defective product to Sicon S.r.l. (or to an authorised centre), with the cost of dismantling and transport
and related expenses borne by the customer or end user.
The decision to repair or replace the defective product or component will be taken at the complete discretion of Sicon S.r.l.
Replacement or repair of parts and any modifications to the product or components during the warranty period shall not extend
the duration of the warranty.
This standard warranty supplements, but does not replace, all other rights of the consumer or purchaser of the product and, in
particular, does not affect statutory consumer rights under Italian Legislative Decree no. 206 of 06/09/2005 (Consumer Code).
Sicon S.r.l. reserves the right to extend this warranty, which must be agreed in writing
2) Procedure
I. Defects must be reported to Sicon S.r.l., SOCOMEC after sales service (via Sila 1/3 – Zona Industriale Scovizze – 36033 Isola
Vicentina - VI), in writing by registered post or electronic mail ([email protected]), or fax [phone]).
In all cases the report submitted to the above Department must be accompanied by a brief description indicating the type
of fault, product serial number, and all details on the ID plate.
A copy of the proof-of-purchase document must be attached to the written report (delivery note, invoice, till receipt, stating
the purchase date and product ID information — model, serial number etc.). If it is not possible to provide proof of purchase,
the serial number and date of manufacture will be used to calculate the probable warranty expiry date.
The defective product can only be returned to Sicon S.r.l. after the acceptance number has been received; this will be issued
by the service centre on receipt of the written report.
II.
The defective product must be returned to Sicon S.r.l. in the original packaging, or equivalent, attaching the return acceptance number.
III. If the goods are acknowledged as being defective and under warranty, Sicon S.r.l. will send the new or repaired product
and/or component to the end user at the address provided in the fault report or, if no address was provided, to the location
where the goods were delivered originally when new, as specified in the sales contract.
IV. Sicon S.r.l will cover the cost of shipping the replacement product and/or component.
V. Installation of the replacement product and/or component must be carried out by a skilled person or authorised service
centre and the relative cost borne by the customer or end user.
VI. Sicon S.r.l. shall be reimbursed for all activities carried out on products and/or components not covered by the warranty, in
accordance with standard company rates and conditions.
VII. Sicon S.r.l. reserves the right to supply a different product and/or component model provided it offers equivalent performance,
if the original defective model under warranty is out of production.
VIII. If on-site assistance from qualified Sicon S.r.l. personnel is requested, labour costs and travel expenses will be borne by the
customer/end user, applying current Sicon S.r.l. rates.

3) Warranty Exclusions
a) The warranty does not cover product and/or component defects consisting of and/or resulting from:
I. accidental damage.
II. negligent, improper or inadequate use of the product or component (for example, use outside tolerance limits: temperature,
humidity, poor ventilation).
III. failure to comply with instructions for installation, use and maintenance described in the Installation and Operating Manuals.
IV. modifications or repairs attempted by persons not authorised by the Sicon S.r.l. After Sales Service.
V. damage due to atmospheric discharges, floods, fires, earthquakes, uprisings, wars or other instances of force majeure or
resulting from any circumstances other than normal inverter operating conditions and beyond the control of Sicon S.r.l..
VI. damage caused by overvoltages.
VII. damage due to corrosion.
VIII. inadequate transport.
IX. failure of the user to comply with current regulations and standards.
b) Similarly, the warranty will be invalidated:
I. if the defective product and/or component is not returned to Sicon S.r.l. in its original packaging or equivalent.
II.
if the serial number identifying the products has been tampered with or is not clearly identifiable.
III. if the defect concerns aesthetic or construction aspects that do not affect normal product operation.
c) The warranty does not cover claims not included under warranty conditions, and in particular, claims for the refund of damages
due to loss of production, loss of earnings, or attributable to product defects or installation/dismantling costs.

This user manual specifies installation and maintenance procedures, technical data and safety instructions for SOCOMEC solar
inverters. For further information visit the Socomec website: www.socomec.com.
Any work carried out on the equipment must be performed by skilled, qualified technicians.
1.1. SAFETY SYMBOLS AND INSTRUCTIONS
WARNING!
Failure to observe safety standards could result in fatal accidents or serious injury, and damage equipment or the
environment.
WARNING! RISK OF ELECTRIC SHOCK!
The equipment includes capacitors that store energy. After disconnecting all power sources wait for the capacitors
to discharge.
WARNING! RISK OF BURNS!
During operation the temperature of the casing may exceed 70 °C. Do not touch the surfaces!
Keep this manual safe for future reference.
Before carrying out any operations on the inverter read the Installation and Operating Manual carefully.
The following precautions must be taken in order to avoid risks of overheating, fire. electric shock, mechanical shock, and collateral
damage (persons and/or property):
• Do not cover or obstruct the air outlet vents.
• Do not install the inverter inside a cabinet in an enclosed, non-ventilated area.
• When installing the inverter comply the recommended clearances (see chapter 4.2).
• Only use accessories recommended or sold by the manufacturer.
• Ensure the wiring is in good condition and not undersized.
• Do not operate the inverter with damaged or substandard wiring.
• Do not operate the inverter if it has suffered a violent mechanical shock of any kind (fall, impact, etc.)
• Before cleaning or performing maintenance work on the inverter or connected appliances, disconnect the power sources. After
disconnecting wait for the internal capacitors to discharge completely (15 minutes approx).
• Inverter earth connection. See Chapter 5.
