Hot Insertion and Removal of I/O Modules
If external power to an I/O module’s field devices is removed, the module itself
can be removed/inserted in an operating system (backplane power and CPU or
NIU active) without affecting the rest of the system. Communications modules
are not hot-insertable or removable.
For hot insertion, the I/O module must be properly seated on the carrier with all
pins connected within 2 seconds. For removal, the module must be completely
disengaged from the carrier within 2 seconds. If hot insertion or removal takes
longer than 2 seconds, a System Misconfiguration fault may be generated,
which may shut down the I/O Station.
CAUTION
Operating equipment may be very hot, especially at higher ambient
temperatures. If the equipment is hot, do not touch it directly.
Such “hot insertion” and removal should not be attempted in hazardous
locations. Personal injury, system malfunction and/or damage to the equipment
may occur.
VersaMax equipment is suitable for use in non-hazardous locations or in Class
1, Div. 2, Groups A, B, C, and D, and Class 1 Zone 2 locations.
Explosion hazard: Substitution of components may impair suitability for Class 1,
Division 2 and Class 1 Zone 2.
NOTE
The VersaMax power supply is not hot-swappable. Hot inserting or extracting
the power supply is an improper method to power down or power up. Hot
inserting the power supply can cause a “Corrupted User Memory Fault”
condition. Power-cycling should only be accomplished by switching the main
power going into the power supply.
