  • Page 7: Installing The Capacitor Control

    . The S&C IntelliCap Plus Automatic Capacitor Control is connected to switchgear operating at primary voltage levels . High voltage may be present in the wiring to the switch control or the switch control itself during certain failures of the switchgear wiring or grounding system, or because of a failure of the switch itself .

  • Page 8: Meter Base Mounting

    Install the control on the meter base, pole, or panel in a location with minimum traffic exposure. All IntelliCap Plus controls have an internal terminal strip; the terminal strip configuration is shown on a label inside the enclosure below the faceplate. The terminal strip wires connect to the meter base or cable connectors.
