3.5.1 Installation Locations to Avoid
Although Ericsson declares this product designed for outdoor environments, avoid installing the unit in a potential
microclimate location. Typical examples of microclimate locations are sites where the product is not only exposed to the
surrounding temperature, but additional temperature as heat from dark-colored planes, for example, reflections from the
street asphalt or walls. The additional temperature can generate heat traps with temperatures up to 10°C higher than
expected.
Avoid installing equipment in the following locations:
– Near the exhaust of building ventilation systems
– Near the exhaust of chimneys
– Opposite large surfaces made of glass or new concrete
If the unit is to be located in an environment subjected to lightning strike, an external Surge Protection Device (SPD) is
needed.
3.5.2 Other Considerations
Installing the radio near other electronic equipment can cause interference.
For sites with risk of ground fire, the recommended minimum installation height is 3 m.
3.5.3 Painting Disclaimer
Ericsson recommends to not paint the product as it can affect performance of the product.
Ericsson applies limitations to the warranty and service contract if the product is painted.
If the product is painted, the following commercial limitations apply:
– Failure modes directly related to overheating because of painting are not valid for repair within the scope of the
warranty or standard service contract.
– Product failures related to paint contamination of components of the unit are not valid for repair within the scope of
warranty or standard service contract.
– When a painted unit is repaired, it might be restored to the standard color before being returned to the market. It is
not possible to guarantee that the same unit is sent back to the same place. This is also valid for units repaired under
a service contract.
– For repairs within the warranty period or a standard service contract, the customer is charged the additional costs for
replacing all painted parts of the unit or the complete unit.
If adaptations are required, contact Ericsson for information.
