General Rules for Attaching Discrete and Analog Input/Output Modules Terminal Blocks
Original instructions
About us
At a glance
Attaching a terminal block to a discrete/analog module is decribed below.
Discrete Modules
DANGER
HAZARD OF ELECTRIC SHOCK, EXPLOSION OR ARC FLASH
Before mounting/removing a discrete module,
  • remove the power to the module (sensors and pre-actuators), and
  • disconnect the terminal block.
  • Always use a properly rated voltage sensing device at all line and load fuse clips to confirm power is off.
Failure to follow these instructions will result in death or serious injury.
Analog Modules
DANGER
HAZARD OF ELECTRIC SHOCK, EXPLOSION OR ARC FLASH
Before mounting/removing an analog module,
  • make sure that the terminal block is still connected to the ground, and
  • remove the power to the module (sensors and pre-actuators).
  • Always use a properly rated voltage sensing device at all line and load fuse clips to confirm power is off.
Failure to follow these instructions will result in death or serious injury.
