What it represents
Identifies a device that performs several separately described protection or control functions.
In a drafting package, connect this reference to the device's enabled-function list. The associated drawing should trace the function-specific outputs and terminal references; the number identifies the role and does not specify the terminal arrangement, ratings or operating settings.
How to read it
- Identify the device's enabled-function list.
- Trace the function-specific outputs and terminal references.
Information to show or reference
- Label the device's enabled-function list.
- Cross-reference the function-specific outputs and terminal references.
- Identify the device tag, manual revision and logic drawing that define this implementation.
A distinction that matters
The number 11 does not reveal which protection elements are enabled; show their individual codes as well.
