NEPSI Approvals

Page 3, 4, and 5 of this errata sheet contain
instructions for safe use in in hazardous locations
and nameplates (see figure 1) for NEPSI approvals.
Refer to the DVC6000f Series FIELDVUE
Valve Controller Instruction Manual − Form 5774,
dated March 2006 or the DVC6000f Series
FIELDVUE R Digital Valve Controller Quick Start
Guide − Form 5778, dated December 2005, for all
other information and instructions pertaining to the
DVC6000f digital valve controller.
Special Instructions for Safe Use and
Installations in Hazardous Locations
Certain nameplates may carry more than one
approval, and each approval may have unique
installation requirements and/or conditions of safe
use.
After reading and understanding these special
special conditions of use, proceed with standard
installation procedures as found in the quick start
guide or instruction manual.
WARNING
Failure to follow these conditions of
safe use could result in personal injury
or property damage from fire or
explosion, or area re-classification.

NEPSI Intrinsic Safety

Notes for Safe Use of the Certified Product
DVC6000f series digital valve controllers
(designated as controller hereafter) have been
proved to be in conformity with the requirements
specified in the national standards GB3836.1-2000
and GB3836.4-2000 through inspections conducted
by National Supervision and Inspection Centre for
Explosion Protection and Safety of Instrumentation
(NEPSI). The Ex marking for the products is Ex ia II
CT6/T5/T4, and their Ex certificate number is
GYJ06280. When using the product, the user should
pay attention to the items stated below:
1. The correlation of approved DVC6000f Series
digital valve controllers in specific product type, Ex
marking and operating ambient temperature this
time is as follows:
R Digital
Mounting Style
Integral Mounting
Separate
Mounting
2. The enclosure of the controller provides a
grounding terminal, and the user should install a
reliable grounding wire connected to it when
mounting and using the controller.
3. The values for intrinsically safe parameters and
maximum internal equivalent parameters of the
controller are as follow:
Max Input
Voltage
4. As a main unit of a separate design product, the
values for intrinsically safe output parameters of
DVC6005f are as follows:
Max Output
Voltage
5. While the controller forms an intrinsically safe
explosion protection system together with an
associated equipment, the following requirements
must be met: Uo vUi, Io vIi, Po vPi, Co wCi + Cc,
Lo wLi + Lc.
6. The connection cable between the product and
associated equipment should be a cable with
