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.
AC INDUCTION MOTORS
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 Appendix – 7 – 12.
