Rack Mounting

The UPS comes with standard 46.5 cm (19") rack mount brackets. It is supplied with four (4) screws to attach the mounting brackets (ears) to the chassis.

Wall Mounting

The brackets on the UPS can be rotated 90° for wall mounting. Remove the screws, rotate the brackets, and insert the screws in the appropriate holes.

Warning!

Do not mount the unit on the wall as shown in the illustrations at left. Doing so could result in a safety hazard.

The interface port is used for factory test and calibration.

Charge the battery pack

The UPS charges its battery pack whenever it is connected to utility power. The battery pack will charge fully during the first 4 hours of normal operation. Do not expect full battery back-up runtime during this initial charge period.

Once the UPS is mounted, please follow the installation instructions in the BayStack Quick Reference Guide.

Operating Instructions

	I/O

With the UPS plugged in, press and release the on/off/test button to supply power to the loads.

The loads are immediately powered while the UPS performs a self-test. Press and release the button again to turn off power to the loads. It may be convenient to use the UPS as a master on/off switch for the protected equipment.

The green on-line LED illuminates when the UPS is supplying utility power to the loads.

Self-test

The UPS performs a self-test automatically when turned on, and every two weeks thereafter. Automatic self-test eases maintenance requirements by eliminating the need for periodic manual self- tests.

During the self-test, the UPS briefly powers the loads on-battery. If the UPS passes the self-test, it returns to on-line operation.

If the UPS turns off during the self-test and emits a fading tone, the batteries are not connected properly.

The loads are not affected by a failed test. Recharge the battery pack overnight and perform the self-test again. If the replace battery LED is still on, replace the battery pack using the Replacing the Battery Pack procedure.

On Battery

During on-battery operation, the yellow on-battery LED illuminates and the UPS sounds an audible alarm consisting of 4 beeps every 30 seconds. The alarm stops when the UPS returns to on-line operation.

Overload

When loads exceed the UPS’s capacity, the red overload LED illuminates and the UPS emits a sustained tone. The alarm remains on until the overload is removed. Disconnect nonessential load equipment from the UPS to eliminate the overload.

If the overload is severe, the input circuit breaker may trip (the resettable center plunger of the circuit breaker pops out). Disconnect nonessential load equipment from the UPS to eliminate the overload and press the plunger back in.

If there is AC power and the circuit breaker does not trip during overload, the loads are still powered. If the circuit breaker trips or the UPS attempts to transfer to battery, the loads’power will be shut off. Turn the UPS off then back on to power the loads.

Replace Battery

If the battery pack fails a self-test, the UPS emits short beeps for one minute and the red replace battery LED illuminates.

The UPS repeats the alarm every five hours. Perform the self-test procedure to confirm replace battery conditions. The alarm stops when the battery pack passes the self-test.

Low Battery

When the UPS is operating on-battery and the energy reserve of the battery pack runs low, the UPS beeps continuously until the UPS shuts down from battery pack exhaustion or returns to on-line operation, if the utility power returns before the battery pack is exhausted.

Cold Start

Note: Cold start is not a normal operating condition.

When the UPS is off and there is no utility power, it is possible to cold start the UPS to power the loads from the UPS’s battery pack.

· Press and hold the on/off/test button until the UPS emits a constant tone.

·Release the on/off/test button during the tone to start the UPS.

Storage

Storage Conditions

Before storing, charge the UPS for at least 8 hours. Cover the UPS and store it lying flat in a cool, dry location, with its battery pack fully charged.

Extended Storage

At -15 to +30 ° C (+5 to +86 ° F), charge the UPS’s battery pack every 6 months.

At +30 to +45 ° C (+86 to +113 ° F), charge the UPS’s battery pack every 3 months.
