  Your CyberPower UPS might not be turning on because it is not connected to a 220-240V outlet. Ensure the unit is properly connected. If that's not the issue, the battery might be worn out, or there could be a mechanical problem. In both of these cases, you should contact CyberPower Systems Technical Support.

  If the outlets on your CyberPower UPS are not providing power, it could be due to a blown fuse or tripped breaker because of an overload, or discharged batteries. First, turn off the UPS and unplug at least one connected device. Then, unplug the UPS power cord and replace the blown fuse with a spare or press the circuit breaker knob. After that, connect the power cord and turn the UPS back on. If the batteries are discharged, allow the unit to recharge for at least 4 hours.

  If the outlets on your CyberPower UPS aren't providing power, the fuse might be blown, or the breaker tripped due to an overload. Turn the UPS off, unplug at least one connected device, and unplug the UPS power cord. Replace the blown fuse with a spare that meets the specifications or press the circuit breaker knob. Then, connect the power cord and turn the UPS back on. Alternatively, the batteries may be discharged. In this case, allow the unit to recharge for at least 4 hours.

DEFINITIONS FOR ILLUMINATED LED INDICATORS

The CyberPower UT650EG, UT800EG, and UT1050EG are uninterruptible power supply (UPS) systems designed to provide temporary backup power and surge protection for connected electronic equipment. These devices are intended for indoor use in temperature and humidity-controlled environments, protecting against power failures, surges, and spikes.

Function Description

The primary function of these UPS units is to safeguard electronic devices, such as computers, monitors, and external data storage, from power disturbances. When utility power is normal, the UPS operates in an energy-saving "ECO Mode" or charges its internal battery. In the event of a power outage, the UPS automatically switches to battery power, providing a continuous power supply to connected equipment for a limited duration, allowing users to safely shut down their systems and prevent data loss. The units also offer protection against voltage surges and spikes, ensuring the longevity of connected electronics.

Important Technical Specifications

The series includes three models with varying capacities:

UT650EG: 650VA / 360W
UT800EG: 800VA / 400W
UT1050EG: 1050VA / 630W

All models operate within an input voltage range of 165-290Vac and support nominal frequencies of 50/60Hz +/-5Hz. The output voltage on battery power is 220/230/240Vac with a frequency of 50/60Hz +/-1%.

For overload protection, the UT650EG and UT800EG models utilize a fuse, while the UT1050EG employs a circuit breaker.

Physical dimensions and weight vary by model:

UT650EG: 84 x 174 x 280 mm (W x H x D), 3.8 kg
UT800EG: 84 x 174 x 280 mm (W x H x D), 4.0 kg
UT1050EG: 95 x 220 x 307 mm (W x H x D), 6.9 kg

The UPS units are equipped with sealed, maintenance-free lead-acid batteries. The UT650EG uses one RBP0119 battery, the UT800EG uses one RBP0143 battery, and the UT1050EG uses two RBP0119 batteries. The typical recharge time to reach 90% of total discharge capacity is approximately 6 hours for all models.

The operating environment for these UPS systems is specified at 0°C to 40°C with a relative humidity of 0% to 90%.

Usage Features

Power Switch: A single power switch controls the ON/OFF state of the UPS. Pressing it for 2 seconds turns the unit ON or OFF.
Alarm Setting: The audible alarm can be toggled ON or OFF by quickly pressing the POWER button twice. Two short beeps indicate the alarm is off, while a single short beep indicates it's on. The default setting is "Alarm On."
LED Indicators: The front panel features LED indicators that provide visual feedback on the UPS status:
- Green ON: Utility is normal, and the UPS is in energy-saving (ECO) mode.
- Green Slowly Flashing: Utility is normal, and the UPS is charging the battery.
- Yellow ON: The UPS is providing battery power.
- Yellow Flash (Rapid Beeping): Low battery, indicating the UPS will soon run out of power.
- Yellow ON, Flash once every 5 seconds (Constant Tone): Battery output short fault.
- Red ON, Flash twice every 5 seconds (Constant Tone): Overload fault, meaning connected equipment exceeds the unit's rating.
- Red ON, Flash 3 times every 5 seconds (Constant Tone): Charger fault.
- Red ON, Flash 4 times every 5 seconds (Constant Tone): Hardware fault.
- Red Flash (Constant Tone): Overload warning.
AC Outlets: The UT650EG and UT800EG models feature three universal AC receptacles, while the UT1050EG has four. These outlets provide temporary uninterrupted power during outages and protection against surges and spikes. It is crucial not to connect high-power devices like laser printers, copiers, space heaters, or vacuum cleaners to these outlets, as this can overload and damage the unit.
Input Power Cord: A fixed input power cord connects the UPS to utility power via a 2-pole, 3-wire grounded wall receptacle. Extension cords should be avoided.

Maintenance Features

Battery Recharging: Upon initial receipt, it is recommended to recharge the battery for at least 8 hours to ensure maximum charge capacity. The unit charges whether it is ON or OFF, as long as it is plugged into an AC outlet. To maintain optimal battery charge, the UPS should remain plugged into an AC outlet at all times.
Overload Protection: The units include either a replaceable fuse or a circuit breaker to protect against overloads. If an overload occurs, an audible alarm will sound, and the unit will emit a long beep. To correct this, the UPS should be turned off, and at least one piece of equipment should be unplugged from the battery-supplied outlets. After waiting 10 seconds, the fuse or circuit breaker should be checked and reset (if applicable) before turning the UPS back on.
Battery Maintenance: Servicing of batteries should only be performed or supervised by personnel knowledgeable of batteries and the necessary precautions. Unauthorized personnel should be kept away from the batteries. For extended storage, the UPS should be covered and stored with a fully charged battery, with recharging recommended every three months to ensure battery life.
Troubleshooting Guide: The manual provides a comprehensive troubleshooting section to address common issues such as unexpected runtime, failure to turn on, or outlets not providing power. Solutions range from recharging the battery and checking connections to contacting CyberPower Systems Technical Support for more complex problems like worn-out batteries, mechanical issues, or damage from surges/spikes.
Cleaning: The UPS should be unplugged prior to cleaning. Liquid or spray detergents should not be used.
Safety Precautions: The manual emphasizes several safety precautions, including installation in a temperature and humidity-controlled indoor area, avoiding obstruction of cooling vents, not exposing the unit to direct sunlight or heat sources, and not connecting non-computer-related or life-support equipment. Liquids or foreign objects should not enter the UPS, and in an emergency, the unit should be turned off and disconnected from the AC power supply.
