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.
☐ The mounting location must be inaccessible to children.
☐ The mounting location must be suitable for the weight and dimensions of the product (see
Section13 "Technical Data", page106).
☐ 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.
☐ The mounting location should be freely and safely accessible at all times without the need for
any auxiliary equipment (such as scaffolding or lifting platforms). Non-fulfillment of these
criteria may restrict servicing.
☐ The DC load-break switch of the product must always be freely accessible.
☐ All ambient conditions must be met (see Section13, page106).
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.
