Effective Grounding Methods
Trident Planning and Installation Guide
Connecting Baseplates to Protective Earth
!
WARNING
Do not operate a Trident system without connecting each baseplate to a protective
earth (AC safety ground) with a low-impedance cable. Improper grounding creates
the potential for dangerous electrical shock—the Trident controller can produce
significant leakage currents which must be shunted to earth.
To ensure that your Trident controller and the equipment connected to it operate
safely, you should follow all applicable local and national codes and standards. At
a minimum, these include national fire and electrical codes. Since codes and
standards vary geographically and change over time, it is your responsibility to
determine which standards apply to your specific case and to comply with them. If
necessary, contact your local Fire Marshall and Electrical Inspector for assistance.
Connect each baseplate in your system to a common tie point, such as a copper bar,
according to the applicable electrical codes. You may use the same copper bar to
provide a protective earth connection for the Trident controller’s field devices and
wiring.
The wire should be:
• Heavy
• Solid or stranded
• Bare or insulated
A 12 AWG (3.3 mm
2
) wire should be adequate in most environments.
