Possible Causes
Pump wired for 230 V but supplied with 400 V, Pump configured for 400 V but supplied with 230 V, Misplaced jumpers in terminal box, Wrong tap selection on autotransformer (if used)
How to Fix / Troubleshooting
Safety first: Immediately disconnect power. Overvoltage can destroy the motor and electronics.
- 1. Check nameplate: Read the Espa pump nameplate to confirm the correct voltage and wiring configuration (e.g., 230 V single-phase, 230/400 V three-phase).
- 2. Inspect terminal wiring: Open the motor terminal box and verify that jumpers and connections match the wiring diagram inside the cover or in the Espa manual.
- 3. Measure supply voltage: Have a qualified electrician measure the actual supply voltage at the pump terminals and confirm it matches the required rating.
- 4. Correct wiring: Adjust jumpers or reconnect windings as per Espa's diagram for the available supply. If the pump has already been exposed to incorrect voltage, the motor or drive may be damaged and require replacement.
