About us
Introduction
In order to protect the signal from outside interference induced in series mode and interference in common mode, we recommend that you take the following precautions.
Cable Shielding
Connect the cable shielding to the grounding bar. Clamp the shielding to the shield bar on the module side. Use the shielding connection kit BMXXSP•••• to connect the shielding.
DANGER
HAZARD OF ELECTRIC SHOCK, EXPLOSION, OR ARC FLASH
While mounting / removing the modules:
  • make sure that each terminal block is still connected to the shield bar and
  • disconnect voltage supplying sensors and pre-actuators.
Failure to follow these instructions will result in death or serious injury.

Using Pre-Actuators Referenced in Relation to the Ground
There are no specific technical constraints for referencing pre-actuators to the ground. It is nevertheless preferable to avoid returning a remote ground potential to the terminal that may be different to the ground potential close by.
NOTE: Sensors and other peripherals may be connected to a grounding point some distance from the module. Such remote ground references may carry considerable potential differences with respect to local ground. Induced currents do not affect the measurement or integrity of the system.
DANGER
HAZARD OF ELECTRIC SHOCK
Ensure that sensors and others peripherals are not exposed through grounding points to voltage potential greater than acceptable limits.
Failure to follow these instructions will result in death or serious injury.
Electromagnetic hazard instructions
CAUTION
UNEXPECTED BEHAVIOR OF APPLICATION
Follow those instructions to reduce electromagnetic perturbations:
Electromagnetic perturbations may lead to an unexpected behavior of the application.
Failure to follow these instructions can result in injury or equipment damage.
