This instruction manual shall only be used for the first installation of the valve coupler
FD0-VC-Ex4.FF. The data sheet containing the electrical data from the EU prototype
test certificate and additional technical information is effectively a part of this opera-
ting instruction. You can find this data sheet under www.pepperl-fuchs.com.
Intended use
The valve coupler FD0-VC-Ex4.FF is used to operate up to four intrinsically safe low
power auxiliary valves and their final position feedback contacts (PFCs; sensors or
mechanical switches) via an intrinsically safe segment of the F
FF-H1.
The valve coupler FD0-VC-Ex4.FF is used in ignition protection II (1) 2G EEx ia IIC
T4.
In case that the valve coupler was used with non-intrinsically safe sig-
nals it must not be used in hazardous area afterwards and/or be
switched with intrinsically safe circuits.
Mounting
The housing of the valve coupler with protection degree IP65 is provided for wall
mounting. For mounting use two screws (max. thread diameter 6 mm) for the through
bores in the housing. The r.h. through bore for mounting the device is provided with a
grounding plate at the side of the screw head so that the device can be grounded di-
rectly via the fixing screw when selecting a suitable place of installation.
When grounding the device via the fixing screw, ensure low-resistance
connection with ground. Otherwise ground via a separate grounding
cable.
Subject to reasonable modifications due to technical advances.
