1 Safety Precautions
You must carefully read the following contents before installation, wiring, operation and maintenance of the
product, and operate strictly according to notes.
1.1 Installation
Install the inverter on a nonflammable object such as metal etc. Otherwise, there may be a risk of fire.
Do not install the inverter in an environment with inflammable gases which may cause explosion.
Install the inverter firmly on an object capable of bearing its weight. Otherwise, the falling of the inverter may cause injury or
damage of human or equipment..
Do not drop any metal foreign matter in the inverter. Otherwise, accident may occur.
Do not install or run the inverter if it is damaged. Otherwise, accident may occur.
1.2 Wiring
Connect a proper circuit-breaker which matches capacity of the inverter on the input power side of the inverter. Otherwise,
human injury, equipment damage or other accident may occur.
The PE terminal of the inverter must be grounded securely. Otherwise, electric shock or fire may occur.
Tighten up power input terminal of power supply and motor input terminal screw. Otherwise, there may be a fire accident.
The wiring must be done by a qualified personnel.
The wiring must be done after the power is cut off and the high-voltage indicator extinguishes.
The input power must conform to the specifications on the nameplate. Otherwise, the inverter may be damaged.
Never connect the output terminals (U, V, W) to the input power. Otherwise it may destroy the inverter.
1.3 Operation

1 Safety Precautions
2
Only when the cover board has been attached, the power can be switched on. Otherwise, there may be a risk
of electric shock.
Do not touch main circuit terminal of the inverter when electrical power is going to the inverter even if the
inverter is in stop state. Otherwise, there may be a risk of electric shock.
Us operation panel ―STOP/RESET‖ key and external controlled terminal to stop the inverter, but not break the main power
supply. otherwise, the inverter may be damaged.
1.4 Maintenance
10 minutes after power is switched off, the inverter can be inspected and repaired. Otherwise, there may be a risk of electric
shock or injury.
Only professional person can maintain the inverter. Otherwise, electric shock or injury may occur.
Do not leave any conductor such as metals in the inverter after repairing it. Otherwise, the inverter may be damaged.
While an inverter which has not been used for a long period is used again, use a voltage regulator to charge the input voltage
gradually until it reaches the rated value, and wait for a while and confirm it is safe. Otherwise, accident may occur.
1.5 Disposal
When the product is discarded, dispose it as an industrial waste. Otherwise, accident may occur.
1.6 Applicable scope of product
Not apply to the machine or system which may cause life danger of human .
If this product is expected to abnormality of this product will occur a major accident or loss, please be sure to add safety device.

2.1 Check upon delivery
Please check the following items when the inverter is firstly packed:
◆ Whether the product is damaged during shipping.
◆ Read data on the nameplate conform whether type and specification of the product are in accordance with
your order.
◆ Check whether the accessories shipped together with the inverter are complete.
The company strictly develops and manufactures the inverter according to ISO9001, if found to have some
unusual, please contact and agent or agent as soon as possible.

2.4 Installation of inverter
2.4.1 Ambient condition
Environment temperature range of inverter: －10℃～50℃. When the ambient temperature is higher than
50℃, please choose well ventilated place and decrease the inverter by 10% for every 5℃ increment.
2.4.2 Installation site
◆No corrosive, flammable or explosive gases or liquids.
◆Humidity: less than 90% RH, no condensation.
◆Vibration: less than 5.9m/s2 (0.6g)
◆Avoid installing it at a place with much dust and metal powder
If users have special installation requirements, please consult and confirm with manufacturer in advance.
2.4.3 Installation space and heat dissipation
The inverter will create heat during operating. In order to ensure good cooling effect, it must be installed
vertically. The converter cooling duct export is available at the base for cold air entrance, to facilitate the
cooling air circulation flow, top and bottom of converter adjacent to the object must meet the minimum
requirements of the distance, as shown below: D6B/L/P series converter can be installed without clearance
side by side direction .
When several inverters are installed in one equipment or control box, horizontal arrangement is
recommended to minimize the mutual thermal influence. If the inverters have to be installed in a vertical row, a
separating board should be provided to prevent the heat from the lower inverter affecting the upper one. If the
cabinet has exhaust fans on its top, the air flow of the fans must be greater than the total out flow of all
inverters. For cabinets without exhaust fans, the top should be left open if possible, if not possible, the area of
the air vents (inlets & outlets) on the top and bottom of the cabinet must be greater than the total area of the
up & down surfaces of individual inverters, and the wind resistance at air vents should be kept as small as
possible.
If the inverter is installed on the wall of a control room, the room should have good ventilation. Installation
methods are shown as following:
