Ordinary Location - Non-Hazardous Area
The Use in Hazardous Locations is only allowed for MACH1040-Family model No´s which are individually labelled “FOR
USE IN CLASS I, DIVISION 2 HAZARDOUS LOCATIONS”
Notes:
The nonincendive field wiring circuit concept allows interconnection of nonincendive field wiring apparatus and associated
nonincendive field wiring apparatus using any of the wiring methods permitted for unclassified locations when certain
parametric conditions are met.

The lower value of (a) and (b) is to apply.
Cable
L
: inductance per unit length of used cable.
Cable
C
: capacitance per unit length of used cable.
Other C-parameters and L-parameters are according to ANSI / ISA 12.12.01 2007 section 7.
Where cable capacitance and inductance values are unavailable, use the following default values: 60pF/foot (200pF/m),
0.2uH/foot (0,7uH/m)
Nonincendive field wiring circuits must be wired in accordance with the National Electrical Code (NEC), NFPA 70 , article
501.

Parameters:
30V 90mA 50pF 2µH
The MACH1040-Family is an open type which must be installed within an enclosure appropriate for
environmental protection.
WARNING - Explosion Hazard – Do not disconnect Equipment while the circuit is live or unless the area
is known to be free of ignitable concentrations.
WARNING – Explosion Hazard – Substitution of any component may impair suitability for Class I,
Division 2.
Do not open when energized.
