3.1 ELECTRICAL REQUIREMENTS &
INFORMATION
Following are general electrical requirements and
information for
Coral Sea .
CAUTION: DO NOT PERFORM
INSTALLATION UNLESS:
1. The System Feed Water Sea Cock Valve is closed.
2. The system main electrical disconnect switch is
switched “OFF”, LOCKED, and TAGGED.
WARNING: ELECTRICAL SHOCK HAZARD.
A Volt / Ohm Meter will be necessary. The
following installation procedures expose
the installer to High Voltage and electrical
shock hazard. Only attempt this if you are a
qualifi ed electrician and only if surrounding
conditions are safe.
CAUTION: Always allow slack in electrical
cables. Allow the cable to enter or leave
from the strain relief in a straight manner
for several inches to ensure proper
connection, to relieve stress to the cable
and fi tting, and to allow ease of detachment
and reattachment for maintenance or
replacement. If electrical cables are pulled
tight causing them to bend at the strain relief,
they will pull out of the strain relief causing
a dangerous electrical shock condition, the
wire may break, and the strain relief will lose
its water-tight integrity.
A. AMPERAGE NOTES
The Electric Motors within the Systems start in series with
time delay between each motor starting after the Touch
Screen “Start” Switch is pressed. First, the Booster Pump
starts, then the main High Pressure Pump Electric Motor
starts. Alternatively, the Booster Pump and High Pressure
Pump may be started manually by accessing the manual
operation mode from the Touch Screen.
During start up, the current of the Booster Pump Electric
Motor surges to “Locked Rotor” amperage for a fraction of
a second after which the current drops to normal running
load. Then the High Pressure Pump Electric Motor starts
and surges to “locked Rotor” amperage for a fraction of
a second after which the current drops to normal running
load.
Therefore, the maximum surge current equals the Booster
Pump Electric Motor normal running amperage plus the
High Pressure Pump Electric Motor starting amperage.
Normal operational amperage equals the normal operating
amperage of the Booster Pump Electric Motor plus the
normal operating amperage of the High Pressure Pump
Electric Motor.
B. POWER SOURCE REQUIREMENTS
Check line voltage and frequency to 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 within this manual.
C. MOTOR ROTATION
Refer to Booster Pump and High Pressure Pump markings
to determine proper rotation.
Three Phase Systems: Ensure proper rotation by jogging
each motor from the manual operation mode.
