AC Input Power Source Requirements<\/h2>\n\n\n\n
    \n
  1. Either of two AC input voltages are acceptable:
    \n
      \n
    1. 110 – 120 VAC (nominal) (+\/- 10%), 1 Phase, 50\/60 Hz, 30 A<\/li>\n\n\n\n
    2. 208 – 230 VAC (nominal) (+\/- 10%), 1 Phase, 50\/60 Hz, 30 A<\/li>\n<\/ol>\n<\/li>\n\n\n\n
    3. A separate circuit breaker should be used for each Seakeeper<\/span><\/span> drive in multiple Seakeeper<\/span><\/span> installations.<\/li>\n<\/ol>\n\n\n\n
      \n\n\n\n

      Spool-Up Power Modes<\/h2>\n\n\n\n

      The Seakeeper<\/span> 7.5 is factory-configured for Default Spool mode, which accelerates the flywheel to operating speed (9700 RPM) in 24 minutes. This mode requires a higher AC power draw during startup (4000 W) but reduces the overall startup duration. For vessels with limited generator capacity or where minimizing peak electrical load is preferred, an optional Low-Power Spool mode can be selected on the display’s Settings page. This mode reduces the startup power demand to only 2300 W, which increases the time required for the flywheel to reach operating speed. Select the spool mode appropriate for the vessel’s electrical system to ensure reliable operation without overloading the AC power source.<\/p>\n\n\n\n

      Drive Box AC Power Input Connection Instructions<\/h2>\n\n\n\n
        \n
      1. Cable: 3 x 10 AWG (3 x 6mm2<\/sup> CSA), 10 ft (3 m) length, Seakeeper<\/span><\/span> supplied pre-installed.
        \n
          \n
        1. Locate AC Power Input Cable to the Drive at the outward of two cable glands per Figure 17.<\/li>\n\n\n\n
        2. Connect AC wires to a 230 V, 30 A (or<\/strong> 110 V, 30 A), double-pole Circuit Breaker at an AC power distribution panel.
