Quick Start Guide
Special Conditions for Safe Use (X):
1. Cable entries must be used which maintain the ingress protection of the enclosure to at
least IP66/68.
2. Unused cable entries must be filled with suitable blanking plugs which maintain the
ingress protection of the enclosure to at least IP66/68.
3. Cable entries and blanking plugs must be suitable for the ambient range of the
apparatus and capable of withstanding a 7J impact test.

Special Conditions for Safe Use (X):
1. This device contains a thin wall diaphragm. Installation, maintenance and use shall take
into account the environmental conditions to which the diaphragm will be subjected.
The manufacturer's instructions for installation and maintenance shall be followed in
detail to assure safety during its expected lifetime.
2. In case of repair, contact the manufacturer for information on the dimensions of the
flameproof joints.
3. Appropriate cable, glands, and plugs need to be suitable for a temperature of 5 °C
greater than the maximum specified temperature for the location where it is installed.
4. The transmitter can be installed in the boundary wall between an area of EPL Ga and the
less hazardous area, EPL Gb. In this configuration, the process connection is installed in
EPL Ga, while the transmitter housing is installed in EPL Gb.
5. The applicable temperature class, ambient temperature range and process temperature
range of the equipment is as follows:
