10.2 Replacing the Electronic Unit
Explosion Risk - Prior to starting work, ensure that there is not a potentially
explosive atmosphere.
Warning
Pulling or inserting of an electronic unit might bring the inputs and outputs of
all other modules temporaryly into an undefined condition.
If the machine/system might be put into a dangerous state as a result of the
removal of an electronic unit, a replacement can only be made once the
machine/system is disconnected from the power.
Caution
Only one electronic unit may be removed from the station at any one time. If
multiple electronic units have to be replaced, this must be done consecutively.
The components in the RSTi-EP series can be destroyed by electrostatic
discharge. Ensure that personnel and work equipment are adequately
grounded.
Caution
Note: Once an electronic unit is removed from a power-feed module, the inputs and outputs of the
subsequent modules are no longer supplied with power. For EP-19xx modules, this is
equivalent to triggering the connected safety equipment.
