2 Installation and Wiring

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.
2
◆Vibration: less than 5.9m/s (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:
