IP54 Protection Class Considerations
A dual-radio system fulfils the requirements of the IP54 protection class.
Notice
However, do not mount the radio in areas where it can be tem-
porarily submerged from an accumulation of water or other liquids (e.g.
when using a high-pressure cleaning device).
The IP54 protection class does not apply when:
■
a remote interface is removed from the radio body or control head.
■
the bungs are removed from the auxiliary connector or the cavity for the
external options connector (fitting an auxiliary connector or external
options connector will not restore the IP54 protection class)
■
a grommet is not installed. For example, grommets on the radio
connecting cable, control-head remote cable, and microphone cord.
■
adding an accessory that is not rated to IP54, for example, a control-
head interface box, or hand-held control-head remote interface box.
Negative Earth Supply
The radios are designed to operate only in a negative earth system.
