3.3 Installation specifications Install the device only when depressurised and without power! For installation the respective regulations for explosion protection have to be fulfilled. For installations outdoor and in damp areas, the following points must be observed: • To ensure that no moisture can get into the connector, the device should be connected electrically immediately after installation. Otherwise a moisture admission has to be prevented e.g. by using a suitable protection cap. • Install the device so it is protected from direct sunlight. In the worst case scenario, the...

3.4 Mounting • Prior to installing the transmitter, it is essential to verify whether the version of the device on hand completely fulfils the technical and safety requirements of the measuring point. This applies in particular to the measuring range, overpressure resistance, temperature, explosion protection and operating voltage. • The device must not be heated by radiated heat (e.g. exposure to the sun) to an electronics housing surface temperature above the maximum permissible ambient temperature. If it is necessary to prevent damage from heat sources, a heat protection (e.g. sun shade)...
