• Modifications to the device can affect the explosion protection and must be carried out by staff authorized to perform such work by Endress+Hauser. • When replacing the probe electronics or opening the connection between the remote cable and the probe, a jumper plug must be used or a short-circuit must be established between the probe contact and the potential equalization conductor to avoid electrostatically charging the probe.
• Observe the pertinent guidelines when interconnecting intrinsically safe circuits (GB3836.13, GB3836.15, GB3836.16). • The device can be connected to the Endress+Hauser FXA291 service tool: refer to the Operating Instructions. • When the intrinsically safe Ex ia circuits of the device are connected to certified intrinsically safe circuits of Category Ex ib for Equipment Groups IIC or IIB, the type of protection changes to Ex ib[ia] IIC or Ex ib[ia] IIB.
