BME AHO 0412 HART Analog Output Module
Using EMC Kits
Introduction
To help shield the BME AHO 0412 signals from outside interference induced in series mode and
interference in common mode, use EMC kits to ground the shielded cables connected to the
module.
Cable Shielding
Connect the cable shielding to the grounding bar. Clamp the shielding to the shield bar on the
module side. Use the BMX XSP 0400/0800/1200 EMC kit to connect the shielding.
DANGER
HAZARD OF ELECTRIC SHOCK, EXPLOSION, OR ARC FLASH
While mounting / removing the modules:
confirm that each terminal block is 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.
