Mounting Points, Seals
and Connectors
Other features illustrated in Figure 2.1 are the mounting points for the
radio, the seal between the control head and radio body, and the
connectors at the rear. The last-named are:
■ RF connector
■ power connector
■ auxiliary connector
■ external options connector (optional)
A bung seals the access to the auxiliary connector when this connector
is not used. A second bung seals the aperture provided for the external
options connector when there is no internal options board with such a
connector. If an options board with a connector is installed, a cover seal
is supplied instead. Whenever the connector is not in use, the cover seal
is fitted over the connector as shown in the figure. The bungs and seals
ensure that the radio is sealed to IP54 standards.
Separation of Control
Head and Radio Body
Figure 2.2 shows the control head detached from the radio body, the
control-head loom between them, and the control-head seal. The seal is
fitted to the front face of the radio body. The loom is shown still
connected to the control-head connector on the radio body. The two
points where the control head is levered off the radio body are indicated
by dot-dash-dot marks on the underside. These lever points are shown
in Figure 2.1. The control head may be attached to the radio body with
the underside of the radio body facing either up or down. Which
orientation is appropriate depends on the installation.
