3.1 Hazardous Area Installation
For hazardous area designation, the Ex installation is described on a separate 'HazLoc' label mounted on
the transmitter body – see Section 3.4.5, page 23.
For protection in Ex d / explosion-proof installations, turn the 2 security screws (located beneath the covers
on front and rear of the housing body) until they prevent both covers from being rotated (unscrewed)
therefore preventing removal of the covers.
3.2 Non-hazardous Area installation
Fig. 3.2 shows a general purpose non-hazardous installation and is for reference only.
