Notes:
1. Installation to be in accordance with the national electric code, NFPA
70, article 504, and ANSI/ISA RP 12.6.
2. Apparatus connected to the system shall not use or generate voltage
greater than 250 VDC.
3. Install intrinsically safe barriers in accordance with barrier instructions.
4. Factory Mutual approved as intrinsically safe for class I, II, and III,
Division 1, Groups C, D, E, F and G, when installed with barriers
shown.
5. Factory Mutual approved as nonincendive for Class I, Division 2,
Groups A, B, C, and D, and suitable for Class II, Division 2, Groups F

nonincendive rating. Max. V = 29.9 VDC.
6. CAUTION: Substitution of components may void Factory Mutual
approval.
7. Ambient temperature range: -30˚ C to 60˚ C.
8. Factory Mutual approved as intrinsically safe for Class I, II and III,
Division 1, Groups C, D, E, F and G when used with an apparatus
meeting the following entity requirements:
Vmax=29.9 VDC Cl=0 Cl is capacitance by the transducer
Imax=65 mA Li= 35 mH Li is inductance contributed by the transducer
9. For DIN connector option, add D to the model number.
