Frequently Asked Questions - OLS1.5KERT2U CyberPower
How do I connect the CyberPower OLS1.5KERT2U to my server?
Connect the input plug to a grounded wall outlet, then plug your server into the UPS outlets. Press the power button to turn on the UPS. The online double-conversion design ensures clean continuous power.
What is the battery runtime at half load?
At 50% load (approx. 675W), the OLS1.5KERT2U typically provides around 10-15 minutes of backup time. Actual runtime depends on battery age, efficiency, and connected equipment.
Can this UPS be mounted in a standard server rack?
Yes, the OLS1.5KERT2U is designed for 2U rackmount installation. It includes rackmount ears and can also be used as a tower unit with the included stand.
What type of output waveform does this UPS provide?
The UPS provides a pure sine wave output, which is compatible with active PFC (power factor correcting) power supplies and sensitive electronic equipment.
How do I replace the battery?
The battery is user-replaceable and hot-swappable. Remove the front faceplate, disconnect the battery connector, slide out the old battery, and install a replacement. Refer to the manual for safety precautions.
What communication options are available?
The UPS features USB and RS-232 ports for connection to a computer, plus an optional SNMP/EMB slot for network management. CyberPower PowerPanel software enables monitoring and automated shutdown.
How do I check the load level on the LCD?
The built-in LCD display shows output load as a percentage, battery capacity, input/output voltage, and fault messages. Use the navigation buttons to cycle through information screens.
What maintenance does the UPS require?
Keep the unit clean and dust-free, ensure adequate ventilation, and perform a battery test periodically. Replace the battery every 3-5 years or when the runtime noticeably decreases.
Can the OLS1.5KERT2U work with a generator?
Yes, the UPS is compatible with generators due to its wide input voltage range and frequency regulation. The online double-conversion produces stable output even when the generator frequency fluctuates.
What is the transfer time to battery power?
This is an online double-conversion UPS, meaning the inverter continuously powers the load. Therefore, the transfer time from utility to battery is zero milliseconds.
