CERTIFIED PRODUCT
This is a controlled 'Related' or 'Schedule'
drawing. No modifications are permitted
without the notification and final approval
of the Certification Engineer (related dwgs.)
or the Certifying Agency (schedule dwgs.).
(1)
- Apparatus which is unspecified except that it
must not
be supplied from, or contain under normal or abnormal conditions a source of potential with respect to earth in excess of 250
V
RMS or 250 VD
C
which is considered to be the Safe Area's maximum voltage.
(2)
- The Barrier or other Associated Apparatus
must
be agency-approved (CSA/FM/SAA/SIRA/UL, etc..) per the
"specific"
installation area for Intrinsically Safe connections (Zones 0/1, Class I / Div. 1)
.
US barriers for USA, Canadian barriers for Canada, ATEX bariers for Europe, IECEx barriers where applicable. The outpu
t voltage
(Voc, Vt or Vo)
must no
t exceed
30 VD
C
& the output
current
(Isc, It or Io)
must not
exceed
110 mA
. Also, it
must
be installed per the manufacturer's guidelines.
A Shunt Zener Barrier is NOT required for Non-Incendive / Type N installations
.
(3)
- The combined Capacitance and Inductance of the inter-connecting cables of the device (hazardous area)
must no
t exceed the values indicated on the Associated Apparatus (safe area).
4- For US applications, installation
must
be in accordance to
'ANSI-P12.6'
(Installation of I.S. Systems for Hazardous 'Classified' Locations) and the National Electric Code
'ANSI/NFPA 70
'. Also,
a
dust-tight conduit seal
must
be used when installed in Class II and Class III environments. For applications in Canada, adhere to the 'Canadian Electric
C
ode C22.1' most current publication on I.S.
installationguidelines. For CENELEC/ATEX and IECEx applications, adhere to 'EN 60079-14:1997' or any equivalent IEC-b
ased, most current and pertaining publication on I.S. installation guidelines.
5-
Warning:
Substitution of components is
NOT
allowed as it may impair the Intrinsic Safety of the unit and/or the Non-Incendive circuit.
DO NO
T
open the unit when either energized or if an explosiv
e
gas/dust atmosphere is present. Disconnect power before servicing. Also read, understand and adhere to the manufactur
er's installation and operating procedures.
6- The maximum power parameters of the COM port (to be used only
in safe/non-hazardous areas) are:
