Charger displays E08 and will not initiate charging; often associated with communication issues with smart meter or CT clamp.

Safety first: CT clamps are installed on live mains conductors. Only a qualified electrician should adjust or install them.

• Check CT clamp placement: Confirm that the CT clamp is installed around the correct conductor (usually the incoming live to the property) and oriented according to the arrow marking.
• Inspect CT cable: Trace the CT cable from the clamp to the Rolec charger. Look for cuts, pinches, or loose terminations at the CT input terminals on the control PCB.
• Verify configuration: In the Rolec app or installer menu, ensure that dynamic load management is enabled only if a CT is installed, and that the CT ratio and phase are correctly set.
• Test with CT disabled (installer mode): Temporarily disable load management in the configuration (if permitted by Rolec) to see if E08 clears. Do not leave permanently disabled if required by installation design.
• Replace CT or PCB if needed: If wiring and configuration are correct but E08 persists, replace the CT clamp first. If the fault remains, the CT input circuit on the control PCB may be defective.
