Module Installation
You will need to rotate the keyswitch (1) to the correct position depending on
the module. Refer to the module’s installation instructions for more
information. Do not change the position of the keyswitch after wiring the
terminal base unit.
Make certain that you only connect terminal base units to other intrinsically
safe system modules or adapters to maintain the integrity of the
intrinsically-safe backplane.
Installation in Division 1/
