Requirements for Mounting
Requirements for the mounting location:
WARNING
Danger to life due to fire or explosion
Despite careful construction, electrical devices can cause fires. This can result in death or serious injury.
- Do not mount the product in areas containing highly flammable materials or gases.
- Do not mount the product in potentially explosive atmospheres.
Requirements:
-
Do not mount the inverter in living areas.
-
The installation site can be exposed to direct solar irradiation. There is, however, the possibility that the product reduces its power output to avoid overheating due to high temperatures.
-
All ambient conditions must be met ( > Technical Data).
-
At least two profile rails must be available for mounting.
-
The support surface of the frame to which the profile rails are attached should be firm and level (e.g. concrete). Non-fulfillment of these criteria may restrict servicing.
Requirements for the profile rails:
-
The profile rails must be designed for the load and orientation of the inverters in the PV system. The profile rails might need to be reinforced.
-
The spacing of the profile rails must be designed for the spacing of the holes in the bracket parts for the mounting bracket.
-
The profile rails must be designed for the clamping range of the mounting bracket.
Dimensions of the profile rails and the clamping range of the mounting bracket (dimensions in mm (in))
Center of gravity:
Dimensions of the center of gravity of the product (dimensions in mm (in))
Permitted and prohibited mounting positions:
-
The product may only be mounted in a permitted position. This will ensure that no moisture can penetrate the product.
-
The product should be mounted such that the LED signals can be read off without difficulty.
Permitted and prohibited mounting positions
Recommended clearances:
To guarantee optimal operation and adequate heat dissipation for the inverter, the following requirements for clearances should be observed. This will prevent the inverter power output from being reduced due to excessive temperatures. However, smaller clearances are permitted without causing any risk.
Prescribed clearances in accordance with the National Electrical Code® or Canadian Electrical Code® CSA C22.1
Under certain conditions, the National Electrical Code® or the Canadian Electrical Code® CSA C22.1 specify greater clearances.
- Ensure that the prescribed clearances in accordance with the National Electrical Code® or Canadian Electrical Code® CSA C22.1 are adhered to.
-
Maintain the recommended clearances to walls as well as to other inverters or objects.
