User Guide DLX Series L00410623-1 13

3.1.2. Operation

The inverter must only be operated in accordance with the information in this User Manual.

NOTICE

The DLX is a grid interactive inverter and must be used exclusively for its designed

purpose, which is to convert PV-generated DC electricity into AC electricity to feed

into the grid

• The inverter must be operated in its original and technically intact condition without any

unauthorized modifications.

• Always keep the values of operation within the limits given in the technical

specifications, due to the risk of possible inverter damage.

CAUTION

Keep the voltage and current within the specified limits! The open circuit voltage,

, must never exceed 600 V

under any conditions. The voltage generated by

the PV modules is inversely proportional to the temperature: at lower

temperatures the PV voltage increases from the product label rating and at higher

temperatures the PV voltage decreases from the product label rating.

• Unintended use may damage the inverter or other electrical equipment, may interfere

with the operation of the inverter, or it can, at worst, cause injury or death to persons

operating and maintaining the inverter.

• Ignoring the instructions and guidelines in this User Manual and not performing regular

maintenance is considered as misuse of the inverter.

3.1.3. Maintenance

Prior to service and maintenance the inverter must always be disconnected on both the

AC and the DC side and be fully discharged. Refer to 8.1. Switch-Off.

NOTICE

Accessing the upper inverter section invalidates the warranty. The inverter covers

are to be opened only by qualified persons due to danger of damage to internal

components.

• The inverter lower cover must only be taken off during electrical connection and

maintenance or repairs.

• No unauthorized modifications may be done to the inverter. Contact the system installer

or the distributor in case of failure.

• Regular maintenance must be performed to maximize the life expectancy of the inverter.

Refer to 8.2. Regularly System Inspection.

• A safety component must always be replaced with the same type and rating.
