What is the Wiring-Fault Indicator?

The LED indicator will illuminate red to warn the user that a wiring problem exists, such as bad ground, missing ground or reversed wiring.

What is bad ground?

If your CyberPower unit shorts out or there is a surge/spike in power, it can become a fire hazard by not properly grounding the wire to the earth ground that is connected to your house.

What is missing ground?

A missing ground can cause electrical shock.

What is reversed wiring?

This is caused by the hot and neutral wires being reversed in the wall outlet.

Solutions to try and diagnose the problem:

Try connecting the CyberPower unit into another outlet. If the wiring-fault light indicator is still illuminated contact an electrician to correct the problem with the faulty wall outlet.

Reasons why your CyberPower product might beep:
UPS systems are designed to make beeping noises to alert users that the UPS is having difficulties by providing quick responses to specific issues.

Types of beeping noises:

1. Beeping twice every 15-45 seconds: The problem with beeping twice noise is usually an indicator that the CyberPower unit is running on battery power only.
2. Long solid beep: This is usually an indicator that you have overloaded your CyberPower unit.
3. Rapidly beeping: This is usually an indicator that your CyberPower product’s battery is almost out of charge.

How to fix each of these beeping noises:

Beep twice every 15-45 seconds:

1. Check to ensure that the unit is correctly plugged into the wall outlet.
2. Ensure the wall outlet is functioning properly by unplugging your CyberPower unit and then plugging it into a different outlet.
3. If the other wall outlet works, then you should still contact an electrician to repair the broke wall outlet.

Long solid beep:

1. Unplug low priority electronics and plug them into the Surge-only outlets on your CyberPower product.
2. If this doesn’t work, unplug the unit from the wall outlet after all the equipment have been unplugged from the unit.
3. Note: this might be an indication that you need a new CyberPower unit that can keep up with the demand that is required.

Rapidly beeping:

1. Turn off the UPS because it’s at about 25% battery and it’s going to shut off soon.
2. Note: turning off the UPS means that the power is out and none of the outlets will work if you turn the UPS off.

Mute beeping:

1. The devices user manual will contain the explicit instructions on which steps to take to mute beeping on your UPS.  Search for your model number in the search box in the navigation to find the product detail page. Locate the “Downloads” tab on the product detail page.  In the “Downloads” tab, you will find a link to the PDF user manual.

Applies to the following CyberPower UPS product lines:
PFC Sinewave, Intelligent LCD, Ecologic, AVR, Standby, PC Battery Backup

The UPS will charge the battery whether the unit is turned on or turned off.

CyberPower Systems encourages environmentally sound methods for disposal and recycling of its UPS products. Please dispose of and/or recycle your UPS and batteries in accordance to the local regulations of your state.

A UPS contains batteries that have battery posts, terminals and related accessories that contain lead and/or lead compounds as well as other chemicals known to the state of California to cause cancer and birth defects or other reproductive harm.

Any device which exceeds the unit’s VA/Watt rating should not be plugged into the outlets. High drain devices, medical equipment, and aquatic equipment also void the unit’s warranty. Below is a list of other devices that also void the warranty.

• Laser printers
• Space heaters
• Copiers
• Paper shredders
• Vacuums
• Curling irons

PowerPanel software is not required for the UPS to provide surge suppression and battery backup. However, installing the PowerPanel software provides additional features and control for the UPS, along with the ability to automatically shut down your computer in event of a power outage.

The USB port can be used with Windows, 2000, XP, Server 2003, Vista, 7, and Server 2008.

Your CyberPower product serial number (S/N) is located on a small white rectangle label located on the bottom or back panel of your UPS system. The serial number will appear in various places depending on the product you are referencing.

The label will have a barcode with a 12-character code right below it–this is your serial number. It may include your product’s model number and the words Made in China.

Many CyberPower UPS units have two sets of outlets. One set is labeled “Battery/Surge” and one set is labeled “Surge”. The outlets labeled “Battery/Surge” are the outlets that will receive battery power during a power failure. You should plug your computer and monitor into these outlets and any externally powered critical data storage device.

Items such as printers, speakers, scanners, and faxes should be plugged into the outlets labeled “Surge.” These outlets are intended for low priority electronics that are not essential to the PC’s main operation.

This is normal operation of the UPS. All CyberPower units perform a self-test routine when they are turned on.

Surge strips cannot be installed before OR after the UPS unit. Doing so will void the UPS’ warranty. If you require additional units, please upgrade your UPS to a unit that has more outlets.

Most of the time this is due to a malfunctioning/dead battery. Feel free to contact our technical support specialists, and they will properly diagnose the problem for you.
