What this block does
Groups the documented integrated primary functions within a selected hybrid switching module.
A simple example
In a switchyard equipment diagram, the primary reference identifies the electrical role of an installed component while the linked equipment schedule and manufacturer drawing supply its exact construction and dimensions. For this reference, the drawing identifies “Module primary connections” at the input and “Integrated switching functions” at the output. Internal boundaries follow the manufacturer configuration.
What the drawings help you do
Start at the named input: Module primary connections. Identify its source device or document and the state represented on the drawing. Follow the named output: Integrated switching functions. Cross-reference its destination and separate the command from confirmation that the equipment responded.

Schematic · HSMR
What it represents
Groups the documented integrated primary functions within a selected hybrid switching module. High-voltage primary equipment carries, interrupts, measures or conditions the main power circuit. Its function, insulation arrangement and equipment boundaries need to be distinguished from the secondary signals used to control it.
In a switchyard equipment diagram, the primary reference identifies the electrical role of an installed component while the linked equipment schedule and manufacturer drawing supply its exact construction and dimensions. For this reference, the drawing identifies “Module primary connections” at the input and “Integrated switching functions” at the output. Internal boundaries follow the manufacturer configuration.
Read the connected power path before interpreting a secondary output or alarm. These original educational component references provide no product dimensions, dielectric rating, installation clearance or construction approval. The functional block is an independent explanation of this named application. Equipment-specific ratings, terminal connections and operating conditions must be established in the project documentation.
How to read it
- Start at the named input: Module primary connections. Identify its source device or document and the state represented on the drawing.
- Follow the named output: Integrated switching functions. Cross-reference its destination and separate the command from confirmation that the equipment responded.
- Internal boundaries follow the manufacturer configuration.
- Read the connected power path before interpreting a secondary output or alarm. These original educational component references provide no product dimensions, dielectric rating, installation clearance or construction approval.
Information to show or reference
- Label the source and connection reference for module primary connections.
- Identify the destination and defined state of integrated switching functions.
- Record the equipment or control-document revision supporting this functional block.
- Check this application limit in the project design: Internal boundaries follow the manufacturer configuration.
A distinction that matters
Internal boundaries follow the manufacturer configuration. This reference describes the named application; it does not establish a new IEC graphical symbol, an ANSI device-function number or an exact manufacturer connection diagram.
