Installation
8 308778U
Intrinsically Safe Installation
Requirements
See FIG. 2.
1. The non-intrinsically safe terminals must not be con-
nected to any device which uses or generates more
than 250 Vrms or dc unless it has been determined
that the voltage has been adequately isolated.
2. The installation must meet the requirements of the
National Electric Code, Canadian Electrical Code
Part I, NFPA 70, Article 504 Resp., Article 505 and
ANSI/ISA 12.06.01.
3. Multiple earthing of components is allowed only if
high integrity equipotential system is realized
between the points of bonding.
4. Do not operate system with safety barrier cover
removed.
5. For ATEX, install per EN 60079-14 and applicable
local and national codes.
6. Cable used to connect sensor and safety barrier
must take capacitance and inductance into account.
The maximum capacitance of the barrier is to be
greater than the cable capacitance plus the sensor
capacitance (Ci). The maximum inductance of the
barrier is to be greater than the cable inductance
plus the sensor inductance (Li).
Find cable capacitance and inductance by:
a. Using the most exacting electrical parameters
provided by the cable manufacturer.
b. Using the electrical parameters determined by
measurement of a sample.
7. Product meets 500 Vac isolation test between the
intrinsically safe circuits and earth ground.
