νUnits in a closed or multi-unit rack assembly may have an operating ambient temperature higher than the ambient temperature of the room. The ambient temperature of an operating switch must not exceed 40oC. If the operating ambient temperature cannot be lowered before this maximum is reached, turn off the switch and let it cool.
