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.
☐ A solid support surface must be available (e.g., concrete or masonry). When mounted on
drywall or similar materials, the product emits audible vibrations during operation which could
be perceived as annoying.
☐ The mounting location must be inaccessible to children.
☐ The mounting location must be suitable for the weight and dimensions of the product (see
Section 13 "Technical Data", page 97).
☐ The mounting location must not be exposed to direct solar irradiation. If the product is
exposed to direct solar irradiation, the exterior plastic parts might age prematurely and
overheating might occur. When becoming too hot, the product reduces its power output to
avoid overheating.
☐ 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 Section 13, page 97).
☐ To ensure optimum operation, the ambient temperature should be between -25°C and
+40°C.
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.
