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.
WARNING
Danger to life due to explosive gases
Explosive gases may escape from the battery and cause an explosion.
• Protect the battery environment from open flames, embers and sparks.
• Install, operate and maintain the battery in accordance with the manufacturer’s specifications.
• Do not burn the battery and do not heat it beyond the permitted temperature.
• Additional measures for lead-acid batteries: Ensure that the battery room is sufficiently ventilated.
☐ 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 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 must be less than 3000 m m above Mean Sea Level (MSL). From altitudes of 2000 m m
above MSL, the power decreases by 0.5% per 100 m.
☐ The mounting location must not hinder access to disconnection devices.
☐ 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.
☐ All ambient conditions must be met (see Section 16, page 175).
☐ The ambient temperature should be below 40°C to ensure optimum operation.
☐ The mounting location of the battery must meet all requirements of the battery manufacturer.
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 in such way that display messages or LED signals can be read without difficulty
and buttons operated.
