REX062 shall be mounted close to the IED. It is recommended that REX060 and REX062 are
mounted in the same cubicle as the IED.
The surface of REX062 unit may be temporarily very hot due to heat dissipation, up
to about 65° C above the ambient temperature. It must be installed to get a open
air convection and prevent contact with combustible material to the surface.
