Instruction Manual

2
• Receivab le signals are only from isolated
secondary source.
• All interface ports (except for Front USB
Connector (Type A) ) are not intended to
be directly connected to a signal source
greater than 30 volts and available current
greater tha
n 5mA.
<ANSI/ISA-12.12.01-2007 - Compliance and
Handling Cautions>
• Suitable for use in Class I, Division 2,
Groups A, B, C, and D Hazardous Loca-
tions only.
• WARNING: Explosion hazard - substitu-
tion of components may impair suitability
for Class I, Division 2.
• WARNING: Explosion hazard - do not dis-
connect equipment while the circuit is live
or unless the area is known to be free of
ignitable concentrations.
<Control Drawing of USB I/F on FP's Front
Module>
The information below concerns the use of
the USB I/F located on the FP unit's front
modules used in Class I, Division 2 Groups
A, B, C, and D hazardous locations (from
Doc No. 35016429).
FP's Front Module
Notes:
(1) Nonincendive Circuit Parameters:
Front USB I/F:
Voc = 5.0 V, Isc = 1.25 A,
Ca = 10 µF, La = 16 µH
(2) Selected Associated Nonincendive Field
Wiring Apparatus shall satisfy the fol-
lowing:
(3) If the electrical parameters of the cable
are unknown, the following values may
be used:
Capacitance = 60pF/ft,
Inductive = 0.20 µH/ft
(4) Nonincendive Field Wiring must be
installed in accordance with article
501.10(B) of the National Electrical
Code ANSI/NFPA 70.
(5) Nonincendive Field Wiring Apparatus
shall not contain or be connected to
another source of power.
