Assembly Site Requirements
DANGER
Danger to life due to fire or explosion.
Do not install inverter in areas with risk of explosion.
Do not install inverter on flammable materials. Uphold fire protection class
according to NFPA regulation.
Do not install inverter in areas where easily flammable materials are stored.
Under no circumstances are the cooling fins of the heat sink to be covered.
WARNING
Danger of accident
When installing and servicing, unrestricted and safe access to the devices
must be ensured.
The following requirements of the installation site must be upheld:
Only vertical installation is permitted as otherwise the cooling of the device cannot be guaranteed
(convection cooling).
Prolonged exposure to direct sunlight can cause an internal temperature rise, leading to power
derating of the device. It is recommended to especially avoid easterly or westerly installation
orientations, or to install a sunshade to mitigate the thermal impact of irradiation.
A fixed wall or a metal construction is necessary for installation. The weight of an inverter amounts
up to 75.6 kg (166 lbs). Relevant construction regulations must be observed.
The device is to be mounted at an appropriate distance from combustible materials.
Installation in non-ventilated ended cabinets and enclosures is not allowed because the unit in
operation emits heat.
To allow for the heat dissipation required, keep the following minimum distances from the ceiling
and wall as well as from neighbouring devices:
