3.2 Motor Power Connections

AC Input Power Source Requirements

1. Either of two AC input voltages are acceptable:
   
   1. 110 – 120 VAC (nominal) (+/- 10%), 1 Phase, 50/60 Hz, 30 A
   2. 208 – 230 VAC (nominal) (+/- 10%), 1 Phase, 50/60 Hz, 20 A
      
2. A separate circuit breaker should be used for each Seakeeper Drive Box in multiple Seakeeper installations.
   
3. The AC power source used must sustain 3500 W power for the spool-up operation of the Seakeeper 5.

Spool-Up Power Modes

The Seakeeper 5 is factory-configured for Default Spool mode, which accelerates the flywheel to operating speed (10,350 RPM) in 24 minutes. This mode requires a higher AC power draw during startup (3500 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.

AC Power Input Connection Instructions

AC Input Cable (3 X 10 AWG or 3X 0.6mm² CSA), 10 ft (3 m) length, Seakeeper supplied pre-installed.

1. Locate AC Input Cable for AC power input to the Drive Box.

2. Connect AC wires in to a 230 V, 20 A (or 110 V, 30 A), double-pole Circuit Breaker at an AC power distribution panel.
