The equipment is intrinsically safe only if all mounting instructions in Section 9.11.2
are followed. If the instrument has been in any way damaged during transportation,
return it to your nearest K-Patents service point for checkup before installation. Never
install a damaged instrument into the process line.
The intrinsically safe sensor PR-23-...-IA/-IF is identified by the nameplate, see Fig-
