Electrical Specifications
Electrical Requirements and Specs
The topics within this chapter address electrical requirements, safety information and specifications for the Aqua
Matic RO Desalination System. For electrical schematics, please refer to the following diagrams in the Appendix:
• Single-Phase Electrical Motor Wiring on page 95
• Three-Phase Electrical Motor Wiring on page 96
• Three Phase Transformer Wiring on page 97
System Safety Check
Danger: Do not perform installation, maintenance or troubleshooting procedures until you have verified the
following conditions:
• The System's Feed Water Sea Cock Valve is closed.
• The System's main electrical disconnect switch is OFF, LOCKED and TAGGED.
Hazard Warning
Danger: ELECTRICAL SHOCK HAZARD The Aqua Matic RO Desalination System installation procedures
expose the installer to high voltage and potential electrical hazards. Technicians should only attempt installation
if (1) they are qualified electricians and (2) surrounding conditions are safe.
Danger: Always allow slack in electrical cables. The cable must be able to enter and leave the strain relief
in a straight manner to ensure proper connection; relieve stress on the cable and fitting; and to allow ease
of detachment and re-attachment (for maintenance and/or replacement). If electrical cables are pulled tight
and bent at the strain relief, then they may detach [from the strain relief]. The result is (1) a dangerous
electrical-shock condition; wire breakage; and loss of the strain relief's water-tight integrity.
Amperage Notes
The electric motors within the Aqua Matic RO Desalination System start in series, with the time delay between
each motor starting after the Touch Screen “Start” Switch is pressed.
1. First, the Booster Pump starts, then the main High Pressure Pump Electric Motor. Alternatively, the Booster
Pump and High Pressure Pump may be started manually by accessing manual operation mode from the Touch
Screen.
2. During start up, the Booster Pump Electric Motor's current surges to “Locked Rotor” amperage for a fraction of
a second, after which, the current drops to a 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.
Thus, the maximum surge current equals the Booster Pump Electric Motor's normal-running amperage plus the
High Pressure Pump Electric Motor's starting amperage. Normal-operational amperage equals the Booster
