1. Introduction
This manual provides essential information for the safe and effective use of your UpBright 27V AC/DC Adapter. This power supply is designed to provide reliable charging for compatible INSE cordless vacuum cleaners. Please read this manual thoroughly before use and retain it for future reference.
2. Safety Information
To ensure safe operation and prevent damage, observe the following precautions:
- Over Voltage Protection (OVP): The adapter is designed to prevent damage from excessive output voltage.
- Over Current Protection (OCP): Protects against damage from excessive output current.
- Short Circuit Protection (SCP): Automatically shuts down in case of a short circuit to prevent damage.
- Temperature Protection: Built-in mechanisms to prevent overheating.
- Ensure the adapter is used only with compatible devices as specified.
- Do not expose the adapter to water, moisture, or extreme temperatures.
- Avoid dropping or subjecting the adapter to strong impacts.
- This charger is designed for direct charging of the vacuum cleaner and may NOT fit dock charging stations.
- If the vacuum's rechargeable battery is old or dead (typically lasts 1 to 3 years), it may not accept a charge. This is a battery issue, not a charger malfunction. A voltmeter can be used to verify charger functionality.
