DLS 300 / 450 / 600
Disclaimer
Warranty claims and responsibilities for direct or indirect damages are excluded if caused by:
• transport or storage damages
• incorrect installation and/or commissioning
• modications, changes or attempted repairs carried out by untrained and unauthorised staff
• incorrect use or inappropriate operation
• inadequate device ventilation
• failure to comply with applicable safety standards
• force majeure (such as lightening, overvoltages, storms, res)
• aesthetic imperfections not affecting the system operation
• damages caused by humidity and/or other environmental conditions
The installer/retailer who installed the DLS must return the faulty system to DELIOS s.r.l. Customer Support
Service, who reserves the right to replace the unit with another unit of equal or higher technical specica-
tions, at their own discretion.

racy of this manual. However, DELIOS s.r.l. cannot accept responsibility for any errors or omissions in this
manual, nor for any damages caused by or associated with its use. No information published in this manual

2 CAUTIONS
These instructions are provided for qualied engineers.
Before carrying out any operations, make sure to have read and understood this manual.
Do not make changes and do not carry out maintenance operations not described in this manual.
The manufacturer does not accept responsibility for injuries to people and damages to things occurred
because the information within this manual has not been read and followed.
The installation procedure must be carried out only by qualied staff.
The operations described herein must be carried out only by qualied engineers.
The customer is civilly liable for the qualications and mental and physical condition of members of staff
who operate this equipment. They must always use personal protective equipment required by the legisla-
tion enforced in the destination country and anything else provided by their employer.
The DLS system can also operate without being connected to the mains (off-grid). In these conditions,
default factory setting requires the inverter output to be automatically connected to ground by an internal
device before starting the off-grid operation. However, should the factory setting need to be changed for
specic requirements, the inverter output will be oating.
When exposed to the sun, PV panels can produce dangerous voltages. We recommend that the proce-
dures required to make the working area safe are carried out.
