Notes:
1.
Intrinsically safe apparatus shall be switches or an Approved
System or Entity device connected in accordance with the
manufacturer´s installation instructions.

The values of La and Ca in the tables on the right side are the
maximum values for combined inductance and capacitance
(including cable inductance and capacitance). The values for La
and Ca marked in grey are the values determined according to
curves and tables of IEC 60079-11, Annex A. These grey marked
values may be used for assessment as per IEC 60079-14,
intrinsically safe circuits with only one source of power.
3.
Suitable separation must be maintained between wiring of each
I.S. input channel.
4.
For Installation in Division 2 or Zone 2 see Certification drawing
for IS1 resp. IS1+ Remote I/O System No. 9400 6 031 004 1 or
9400 6 031 006 1 as part of the documentation of the CPU &
Power Modules.
The Type 9470 Digital Input Output Module is designed to receive up
to 16 discrete input signals from dry contacts and NAMUR proximity
sensors etc. and transfer them to the IS1 CPU & Power Module. It is
also possible to drive low power valves. The module is nonincendive
for installation in a Class I, II, III, Division 2, Group A-G or Class I,
Zone 2, Group IIC/IIB hazardous location according to NEC Article
504/505 or Canadian Electrical Code, CSA C22; Providing intrinsically
safe connections for Class I, Division 1, Groups A-G or Class I, Zone
0, Group IIC/IIB hazardous locations listed below.
Entity parameters for wiring configuration to the left are as follows:
