Installation of Quantum Intrinsically Safe Modules
Quantum Intrinsically Safe modules are designed to fit into a standard
140XBPOXX00 Quantum backplane. The modules can be installed in any slot
position in the backplane. (The first slot is normally reserved for the power supply
module.)
Hot Swapping
Hot swapping Quantum Intrinsically Safe modules is not allowed per intrinsic safety
standards.
Safe Area Wiring Practices
Intrinsically safe wiring between Quantum Intrinsically Safe modules and the field
devices located in the hazardous area must be separated from all other wiring. This
can be accomplished by the following methods:
z Separate blue wire ducts, raceways or conduits
z Grounded metal or insulated partitions between the intrinsically safe and non-
intrinsically safe wiring
z a separation of two inches (50 mm) of air space between the intrinsically safe
and non-intrinsically safe wiring. With this method, the intrinsically safe and non-
intrinsically safe wires must be tied down in separate bundles to maintain the
required separation.
Identification and Labeling
Intrinsically safe wiring must be properly identified and labeled. Light blue color
coding should be used for all intrinsically safe wiring. The terminal strip wiring
connector on all Quantum Intrinsically Safe modules is colored blue to distinguish it
from all non-intrinsically safe modules.
All wire ducts, raceways, cable trays, and open wiring must be labeled "Intrinsically
Safe Wiring" with a maximum spacing of 25 ft. between labels.
WARNING
Hot Swap
Do not attempt to hot swap a Quantum Intrinsically Safe module.
Failure to follow these instructions can result in death, serious injury, or
equipment damage.
