  • Page 5: Safety Precautions

    Safety Precautions DANGER The S&C IntelliCap Plus Automatic Capacitor Control line voltage input range is 93 to 276 Vac. Failure to observe the precautions below will result in serious personal injury or death. Some of these precautions may differ from your company’s operating procedures and rules .
  • Page 6: Pre-Installation Instructions

    S&C Electric Company. Pre-Installation Before installing the IntelliCap Plus control, carry out the following steps in the shop: Checklist STEP 1. Inspect the control for visible damage.
  • 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.

  • Page 18: Harness Wiring

    The IntelliCap Plus relay contacts are rated at 20 A at 250 Vac, 1 HP 120/250 Vac. In addition they have been tested to operate three Joslyn Vacuum Switches (36 A). If you need 125 Vdc to operate the capacitor switches, install interposing relays rated for 125 Vdc.
  • Page 19: 220-Volt Wiring

    240-volt output that has the center tap referenced to ground, connect the center tap to the Ac Neutral input and the high line to the Ac Line input of the IntelliCap Plus control. Use two auxiliary relays with 120-volt coils and 240-volt contacts rated to meet the requirements of the capacitor switch, and connect as indicated in Figure 20.
  • Page 20: Connecting Sensors

    Installing the Capacitor Control Connecting Sensors Some controls have var and/or neutral current or neutral voltage sensing connected in the meter socket. Other controls use connector(s) on the bottom of the control enclosure or terminal block J6. See Figure 11 on page 12 and Figure 19 on page 17, respectively. NOTICE Do not ground sensor cable shields at the top of the pole .

  • Page 22: Energize And Test The Control

    (a) Observe that the LCD screen shows: **UnitOK**. If it shows: **ACTIVE ALARMS**, check the capacitor bank for a problem. The alarm condition must be corrected before the IntelliCap Plus control will operate correctly. (b) Check that the LCD screen is scrolling through the real-time and setpoint data. If the display is blank or if there is an error message, see Instruction Sheet 1023-550, “S&C IntelliCap Plus Automatic Capacitor Control: Troubleshooting.”...
  • Page 23: Communication Equipment

    A UtiliNet Radio should have a blinking pilot light. For most installations, the radio is installed in the enclosure door. The IntelliCap Plus control has two remote communication ports. When used with suitable communication equipment and protocols, you can remotely monitor and control the capacitor control installation.
  • Page 24: Connecting Communication Hardware

    For more information, see the appropriate communication points list, or contact S&C Electric Company. Connecting All IntelliCap Plus controls are radio ready.
