REX061 shall be mounted close to the generator in order to
limit the exposure of the field circuit. Alternatively it can be
located in the excitation cubicle.
The surface of REX061 unit may be
temporarily very hot due to heat
dissipation, up to about 50° C above the
ambient temperature. It must be installed
to get a open air convection and prevent
contact with combustible material to the
surface.
