6.2 HANDLING OF ELECTROSTATIC SENSITIVE DEVICES
Some components on the ST150M PCB are sensitive to electrostatic discharge (ESD). The following general guidelines can help
reduce damage due to ESD.
1. Use a grounding bracelet if possible, to minimize charge build-up on personnel.
2. Handle the ST150M PCB by the edges without touching components or printed circuit paths.
3. Store the ST150M PCB in static sensitive packaging whenever possible.
NOTE: Failure to adhere to ESD guidelines will void the product warranty.
6.3 WIRING
Proper installation and field wiring practices are important to follow. Users and installers should familiarize themselves with the
requirements of all applicable codes, laws, and standards.
6.4 NOISE SOURCES
Electrical noise is an important consideration in any installation of the ST150M. When possible, sufficient physical separation
should be maintained between electrical noise sources and the ST150M.
