The Type 9440/15-01-11 CPU & Power Module is an nonincendive
module for installation in Class I, Division 2, Group A-D or Class I,
Zone 2, Group IIC/IIB hazardous location; Providing intrinsically safe
BusRail and nonincendive RS485 interfaces according to NEC Article
504/505 or Canadian Electrical Code, CSA C22.
Safety data for wiring configurations to the left are as follows:

Electrical Apparatus connected to an intrinsically safe system
must not use or generate voltages > 250 V (Umax)
3.
Do not connect or disconnect non I.S. power supply to X5 unless
area is known to be non-hazardous.
4.
Do not detach from or plug the CPU & Power Module to the
BusRail when energized, unless area is known to be non-
hazardous.
