Apc back ups 1250 manual

The unit is being charged whenever it is connected to utility power, whether the unit is turned ON or OFF. If the red Building Wiring Fault indicator located on the end near the power cord is lit, your building wiring presents a shock hazard that should be corrected by a qualified electrician. Low Battery Warning - UPS is supplying battery power to the load connected to the Battery outlets and the battery is near exhaustion. Overload Shutdown - During On Battery operation a battery power supplied outlet overload was detected.

Sleep Mode - During On Battery operation the battery power has been completely exhausted and the UPS is waiting for utility power to return to normal. This will force the UPS to oper. Inspect the UPS upon receipt. Notify the carrier and dealer if there is damage. The packaging is recyclable; save it for reuse or dispose of it properly.

Install the UPS in a protected area that is free of excessive dust and has adequate air flow. Do not operate the UPS where the temperature and humidity is outside the specified limits. The UPS charges its battery whenever it is connected to utility power.

The battery will charge fully during the first 4 hours of normal operation. Do not expect full runtime during this initial charge period. Power management software and interface kits can be used with this UPS.

Use only kits supplied or approved by the manufacturer. If used, connect the interface cable to the 9-pin computer interface port on the back panel of the UPS. Tighten the screw to secure the lead. The UPS detects line voltage distortions such as spikes, notches, dips, and swells, as well as distortions caused by operation with inexpensive fuel-powered generators.

By default, the UPS reacts to distortions by transferring to on-battery operation to protect the loads. Where power quality is poor, the UPS may frequently transfer to on-battery operation. If the loads can operate normally under such conditions, battery capacity and service life may be conserved by reducing the sensitivity of the UPS. Use a pointed object such as a pen to press the button. Press it again to set the sensitivity to low. Press the button a third time to reset normal sensitivity.

When it is set to reduced sensitivity, the LED is dimly lit. When it is set to low sensitivity, the LED is off. By default, the low battery warning occurs when there are approximately two minutes of on-battery run time remaining.

This may not be enough time to gracefully shut down some protected computer systems. Press the configuration button once to set the low battery warning interval to approximately five minutes.

Press it again to set the interval to approximately seven minutes. Press the button a third time to reset the interval to two minutes. The loads are immediately powered while the UPS performs a. Nominal Output Voltage V. Nominal Input Voltage V. Cord Length 6ft 1. Preserves battery life and maximizes runtime by correcting low voltages without discharging the battery.

Product Distribution Canada, United States. Technical Specifications Print. Efficiency at Full Load Topology Line interactive. Waveform type Stepped approximation to a sinewave. Transfer Time 8 ms typical : 12 ms maximum. Bypass Built-in bypass. Number of Power Cords 1. Battery type Lead-acid battery. Included Battery Modules 1. Typical recharge time 16hour s. Product Support. Product Overview Technical Specifications. Run time for load Min-max. Run time for load. Enter the total load power draw of all devices to be protected by the UPS here.

Based on the value entered we will estimate the run time that you will have during a total power outage. Adding run time increases availability by allowing the system to operate through longer outages without shutting down. Capacity Used. The maximum percentage of UPS capacity used to support your specified load. Nominal Output Voltage V. Nominal Input Voltage V. Cord Length 6ft 1. Maximum Input Current Maximizes useful battery life by widening the input voltage window or tightening the output voltage regulation.

Provides notification of changing utility power and UPS power conditions. Periodic battery self-test ensures early detection of a battery that needs to be replaced. Reserves power capacity and run time for connected equipment that require UPS battery back-up while providing surge only protection for less critical equipment.
