The devices should be assembled such that they are not imposed to direct solar radiation or abrubt change in temperature which
might cause condensation.
Commissioning at temperatures v0 _C is permissible only if the site conditions ensure that no command output can be activated
unless the device temperature has reached 0 _C.
