11 ELECTRICAL INFORMATION
11.1 ELECTRICAL REQUIREMENTS
The Electric Motors within the Horizon Seafari
systems start in series with time delay between each
motor starting. First, the Booster Pump starts, then
the main High Pressure Pump Electric Motor starts.
For a normal Marine Ship installation, the current
surges with the Booster Pump starting, then drop
down to Booster Pump Electric Motor running
Amperes. At the instant of the High Pressure Pump
starting, the current surges up again then drop down
to normal system running amperage.
Therefore, the Maximum surge current equals the
Booster Pump Running Amperage plus the High
Pressure Pump Starting Amperage. The normal
running Amperage equals both the Booster Pump
Motor and High pressure Pump Motor combined
running Amperage.

After unpacking, check for damage. Be sure that the
shaft rotates freely.
Check line voltage, frequency and phase, ensure that
it agrees with system nameplate. Grounding and
circuit protection should be done in accordance with
National Electrical Code. See connection diagram
on nameplate of motor or refer to the diagrams on
pages 11-4 through 11-9.
