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.
