What you will see
- A cooling, temperature-control or auxiliary-system warning.
- Reduced charging or discharging alongside the warning.
- A change in the cabinet’s usual operating sound.
- Liquid visible near a cabinet or its cooling equipment.
Why it happens
Sunwoda’s Oasis-L344 manual, for example, describes a temperature-control system involving a liquid cooler, piping and cooling plates under battery-management control. This illustrates why cabinet cooling is a separate subsystem requiring model-specific diagnosis.
The service team should establish which component reports the alarm and whether the battery has entered a protective state. External conditions, maintenance history and auxiliary-system status belong in the review.
Do not assume that room air-conditioning repairs a fault inside the cabinet’s own cooling system. Likewise, a visible liquid cannot safely be identified or handled from appearance alone.
The cabinet has its own cooling
Room air-conditioning does not repair a fault in the cabinet’s own cooling.
What you can check yourself
- Save the alarm from a remote or safely accessible display.
- Record when it appeared and the operating state beforehand.
- Gather cabinet details and maintenance records.
- Report nearby building work or environmental changes.
- Observe only from a safe position. If there is smoke, unusual odour, hissing or a fire alert, follow the emergency plan rather than approaching for more information.
What not to do
- Do not open the cabinet, add coolant, bypass a sensor or reset protective limits. Do not direct water at the equipment or run an improvised fan through an open enclosure.
When to call us
- Report persistent cooling alarms promptly and follow the model-specific operating instructions. Signs of an active incident require emergency assistance.
