2.1 Exterior Size and Mounting Size (See Appendix 1)

2.2 Mounting Place Requirement and Management

Attention

· Don’t carry the inverter by its cover. The cover cannot support the weight of the

inverter and may drop.

· Please install the inverter on a strong support, failing which the inverter may fall off.

· Don’t install the inverter in places where water pipes may leak onto it.

· Don’t allow screws, washers and other metal foreign matters to fall inside the

inverter, otherwise there is a danger of fire or damage.

· Don’t operate the inverter if parts are not complete, otherwise there is a danger of

fire or human injury.

· Don’t install the inverter under direct sunshine; otherwise, it may be damaged.

· Don’t short circuit PB, + and -, otherwise there is a danger of fire or the inverter may

be damaged.

· Cable lugs must be connected to main terminals firmly.

· Don’t apply supply voltage (AC 220V or higher) to control terminals except

terminals TA,TB,TC.

Please mount the inverter as following application occasions and maintain appropriate

condition.

2.2.1 Installation Location

The installation location should meet the following conditions:

●Good indoor ventilation;

●Ambient temperature: -10 ℃ ~ 40 ℃. If the temperature is higher than 40 ℃, the

inverter should be derating used and forced ventilation is required;

●

Humidity should be lower than 95%, no condensing;

●Do not mount the inverter on the timber or other combustible matters;

●Avoid direct sunlight;

●Mount in the location free of dust, metal powder, corrosive gas or combustible gas;

●The installation foundation should be solid and free of vibration;

●No electromagnetic interference, away from source of interference;

●Derating use must be considered when the inverter is installed at high altitude, greater

than 1000 m. This is because the cooling effect of inverter is deteriorated because of the

thin air. Derating 6% per 1000 m higher of the altitude.
