The Isolating Switching Amplifiers Model N-132/1-E-10 and
N-132/2-E-10 are associated apparatuses as well as a nonincendive
apparatuses for installation in non-hazardous, Class I, Division 2 or
Zone 2 hazardous (Classified) Locations and provides intrinsically
safe connections for one (or two) field devices located in Class I, II,
III, Division 1, Group A-G or Class I, Zone 0 [AEx ia] Group IIC,
hazardous locations according to NEC Article 504/505 as listed
below.

3. Electrical apparatus connected to an intrinsically safe system should not use or generate voltages > 250 V (U
max
).
4. Installation should be in accordance with Article 504/505 of the National Electrical Code , ANSI/NFPA 70 and
ANSI/ISA RP 12.06.01
5. Use a general purpose enclosure meeting the requirements of ANSI/ISA S82.02.01 for use in non-hazardous or
Class I, Division 2, hazardous (Classified) locations.
6. Use an FM Approved Dust-ignition proof enclosure appropriate for environmental protection in Class II, Division 1,
Groups E,F and G; and Class III, hazardous (Classified) locations.
7. Each channel shall be installed within a separately shielded cable or a single cable with a separate shield for each channel.
8. These modules are to be mounted on DIN rail, DIN rail with pac-Bus.
The field wiring in any case is connected to the device terminals.
9. Ambient temperature: -
20 °C … +70 °C (any mounting position)
