The devices can operate continuously in closed rooms and in conditions according to
paragraph 7.4.1 of this Operating Manual . The devices should not be directly exposed
to sunlight. Ventilation slots must not be plugged. We do not recommend to put the devices on
heat sources, although they can be placed on another device of the same type or installed
in a rack together with other devices. However, such an arrangement requires a free air flow or,
if necessary, forced ventilation.
