Hazardous locations
Check that the ODUs will not be exposed to hazardous gases, as defined by HAZLOC (USA) and
ATEX (Europe) regulations. If there is a risk of such exposure, then order the PTP/PMP 450i
ATEX/Hazloc product variants, as these are intended for operation in locations with gas hazards.
The ATEX and HAZLOC standards limit the EIRP as shown in Table 66.
