Setup

1. Placement:

Place the Back-UPS in a location that protects it from excessive dust, temperature, and humidity. Avoid placing it near heat sources or in direct sunlight. Ensure adequate airflow around the unit.

2. Connecting to Power:

1. Ensure the UPS is turned off.
2. Plug the UPS power cord directly into a grounded 110V AC wall outlet. Do not use extension cords or surge protectors.

3. Connecting Equipment:

The Back-UPS CS 500VA has six outlets.

• Battery Backup & Surge Protected Outlets (3 outlets): Connect critical equipment such as your computer, monitor, and external hard drives to these outlets. These devices will receive power from the battery during an outage.
• Surge Only Outlets (3 outlets): Connect non-critical equipment such as printers, scanners, or speakers to these outlets. These devices are protected from surges but will not receive battery power during an outage.

4. Initial Battery Charge:

Allow the Back-UPS to charge for at least 8 hours before connecting any equipment. This ensures maximum battery runtime. The unit will charge whether it is turned on or off, as long as it is connected to utility power.

Operation

Turning On/Off:

• To Turn On: Press the power button firmly until you hear a short beep. The "On Line" indicator will illuminate.
• To Turn Off: Press the power button firmly until you hear a long beep. All indicators will turn off.

Understanding Indicators:

Refer to the "Product Overview" section for a description of each indicator light.

Battery Runtime:

The Back-UPS CS 500VA provides approximately 3 minutes of standby power at full load (300W). Runtime will vary based on the connected load.

Self-Test:

The UPS performs an automatic self-test periodically. You can also initiate a manual self-test by briefly pressing the power button while the unit is online. The UPS will switch to battery power for a few seconds and then return to utility power.

Maintenance

Battery Replacement:

The battery in your Back-UPS is a sealed lead-acid battery and is not user-serviceable beyond replacement. When the "Replace Battery" indicator illuminates, the battery needs to be replaced. Contact APC support or an authorized service center for replacement battery information.

Note: After replacing the battery, allow the new battery to charge for 8 hours to ensure full capacity.

Cleaning:

Clean the exterior of the UPS with a soft, dry cloth. Do not use liquid or aerosol cleaners.

Storage:

If storing the UPS for an extended period, charge the battery every three months to prevent battery degradation. Store in a cool, dry place.
