H.2.4 FISCO (Fieldbus intrinsically safe concept)
The XMT1000 Fieldbus is certified as a FISCO connection for
both entity and FISCO parameters:
•
FISCO Parameters

Note: The XMT1000 FISCO control drawing is Panametrics
drawing #752-584. Please consult the factory for a copy of
the drawing.
Attention!
The FISCO cover must be installed to comply
with FISCO guidelines.
IMPORTANT:
The FISCO cover on the XMT1000 terminal PCB is required to
provide a barrier between IS and non-IS connections. This
cover must be installed if the Fieldbus application is FISCO.
The FISCO cover should come installed from the factory, as
shown in Figure 128 below. The Fieldbus cables should be
installed through the XMT1000 upper right port for direct
entry into the FISCO zone on the terminal PCB.
