1.2.7 6270 Optional Equipment Unit (OEU)
The G4 EX unit is designed to be located in DIV 1 Hazardous areas; therefore,
many features and requirements of the unit are housed in a separate enclosure
that is located in DIV 2 or General Purpose areas.
Space is provided inside the enclosure to house a variety of remote
communication devices: transceiver, cellular phone, battery, changing source and
additional I/O (see Figure 1–18).
