Product Overview
The E-SPD TT 11000 Ebara inverter is designed for electric pumps to pressurize hydraulic systems by measuring pressure and flow. This inverter maintains constant pressure in a hydraulic circuit by varying the pump's revolutions per minute. It automatically starts and stops based on hydraulic demand through integrated sensors. Its versatile operating modes and configurable input/output contacts allow adaptation to various system requirements.
Key Features:
- Constant pressure control for optimal comfort.
- Energy consumption reduction through inverter technology.
- Integrated pressure sensor, flow switch, and non-return valve, eliminating the need for external components.
- User-friendly OLED display for intuitive parameter viewing and modification.
- Assisted installation for simplified setup.
- Air-cooled design, directly installable on the electric pump's terminal board.

Applications
This inverter is suitable for a wide range of applications requiring constant pressure in hydraulic systems:
- Residential buildings
- Water supply from wells
- Condominiums
- Irrigation for greenhouses, gardens, and agriculture
- Campsites
- Rainwater harvesting systems
- Swimming pools
- Industrial plants
- Farms
Setup
1. Unpacking and Inspection
- Carefully remove the inverter from its packaging.
- Inspect the unit for any signs of damage during transit. If damage is found, do not proceed with installation and contact your supplier.
- Verify that all components listed in the packing list are present.
2. Mounting
The E-SPD TT 11000 Ebara inverter is designed for direct installation on the electric pump's terminal board. Ensure the mounting location is:
- Protected from direct sunlight and extreme temperatures.
- Free from excessive vibration.
- Well-ventilated to allow for proper air cooling.
- Accessible for maintenance and operation.
If using a wall mounting kit (available separately for some variants), follow the instructions provided with the kit for secure installation.

3. Electrical Connections
All electrical connections must be performed by a qualified electrician in accordance with local regulations and safety standards.
- Ensure the main power supply is disconnected before making any connections.
- Connect the power supply cables to the designated terminals on the inverter. Refer to the wiring diagram provided with the product for specific terminal identification.
- Connect the electric pump cables to the inverter's output terminals.
- Ensure proper grounding of the inverter and the pump.
- If external sensors or control signals are used, connect them to the configurable input/output contacts as per the system design.

Operating Instructions
1. Initial Start-up
- After all electrical connections are secure, restore power to the inverter.
- The OLED display will illuminate. The inverter features an assisted installation process. Follow the on-screen prompts to configure essential parameters such as desired pressure, pump type, and motor characteristics.
- Confirm all settings before proceeding.
2. Parameter Settings
The OLED display provides an intuitive interface for adjusting operating parameters. Navigate through the menus using the control buttons (refer to the product's specific button layout for details).
- Set Pressure: Adjust the desired system pressure. The inverter will work to maintain this value.
- Minimum Frequency: Set the lowest operating frequency for the pump.
- Maximum Frequency: Set the highest operating frequency for the pump.
- Dry Run Protection: Configure settings to protect the pump from operating without water.
- Overcurrent Protection: Adjust limits to prevent motor damage from excessive current.
3. Normal Operation
Once configured, the inverter will automatically manage the pump's operation to maintain the set pressure. The pump will start when pressure drops below the set point and modulate its speed to meet demand. When demand ceases, the pump will stop after a short delay or when a minimum flow is detected.
Maintenance
Regular maintenance ensures optimal performance and extends the lifespan of your inverter and pump system.
- Periodic Cleaning: Keep the inverter's cooling fins and ventilation openings free from dust and debris to ensure efficient air cooling. Use a soft, dry cloth for cleaning.
- Connection Checks: Periodically inspect all electrical connections for tightness and signs of corrosion. Tighten any loose connections.
- System Monitoring: Regularly check the OLED display for any error messages or unusual operating parameters.
- Water Quality: Ensure the water being pumped is free from excessive sediment or corrosive elements that could affect the pump or internal sensors.
Always disconnect power before performing any maintenance or inspection.
