N/A | 230V system inoperative | No site power | Check site supply | DIY Safe |
N/A | 230V system inoperative | RCD/MCB switches tripped out | Reset circuit breakers | DIY Safe |
N/A | RCD/MCB keeps tripping out | Fault on 230V supply | Check supply including polarity | DIY Safe |
N/A | RCD/MCB keeps tripping out | Faulty appliance | Switch every appliance off, reset the circuit breakers, then switch appliances back on one at a time until the fault reappears - that identifies and isolates the faulty one. | DIY Safe |
N/A | RCD/MCB keeps tripping out | Overload on current consumption by appliance | 10A maximum available; do not use appliance | Professional Intervention Required |
N/A | Battery charger does not operate | Charger switched off | Switch on at control box/check MCB is on | DIY Safe |
N/A | No 230V output from the PSU | The lead linking the site supply to the vehicle isn't plugged in | Check the lead is connected correctly at both ends. | DIY Safe |
N/A | No 230V output from the PSU | RCD switched off | Reset the RCD. | DIY Safe |
N/A | No 230V output from the PSU | RCD not operating | Check the supply polarity; if the RCD keeps failing, contact your dealer, as there's likely an equipment or wiring fault. | DIY Check / Tech Fallback |
N/A | No 230V output from the PSU | MCB switched off | Reset the MCB by switching it off (down) then back on (up); if it keeps tripping, contact your dealer, as there's likely an equipment or wiring fault. | DIY Check / Tech Fallback |
N/A | No 230V output from the PSU | No or deficient supply from the site | Contact the site warden for assistance. | Professional Intervention Required |
N/A | Reverse polarity warning light is illuminated on the PSU | — | This light is designed to catch a reversed/crossed live and neutral supply on UK-wired sites - if it comes on, suspect a fault with the site's own supply, or its connecting cable (outside the UK it can light up with no actual fault present, so check with the site warden). It can also light up quite normally when running from certain generators, since some centre-tap their earth connection rather than earthing the neutral directly, leaving both conductors roughly 110V above earth - usually still safe to keep using in that case, but check the generator's own handbook. | DIY Check / Tech Fallback |
N/A | Control Panel has no display | — | The screen's backlight might have simply turned itself off - tap select to wake it again. If that's not it, work through the batteries and fuses, confirm both the shutdown switch and the charger switch on the PSU are set to on, and that mains is plugged in. Also check the lead running between the PSU and the back of the panel.
Still nothing? Get in touch with your dealer. | DIY Check / Tech Fallback |
N/A | 12V power turns off unexpectedly | — | Usually the battery-protect feature has stepped in to protect the vehicle and/or leisure battery, or the engine's been started, in which case equipment is disconnected automatically to meet EMC requirements while driving. | DIY Safe |
N/A | Control panel is locked or behaves erratically | — | Check you're following the control panel's own handling instructions. If the panel's software has crashed, reboot it by turning off the PSU's isolator switch, waiting 30 seconds, then switching it back on. | DIY Safe |
N/A | No 12 volt output from the PSU | No 230V supply | Work through the 230V checks above first. | DIY Safe |
N/A | No 12 volt output from the PSU | Charger not switched on | Turn the charger switch on - it will illuminate when active. | DIY Safe |
N/A | No 12 volt output from the PSU | Battery not connected and/or not charged | Fit a charged battery. | DIY Safe |
Recommended partAffiliate linksView partHideOnly if your leisure battery needs replacing - check the size, type and terminal layout of the one fitted now, and that your charger supports it, before ordering: Leisure batteries vary by vehicle (size, capacity and type - lead-acid, AGM, EFB or lithium). This is a widely used 100Ah EFB battery, not a documented exact match for your vehicle.
