Basic Connection and Start-Up

EPO Port Connection

This optional feature is only for those applications that require

connection to a facility’s Emergency Power Off (EPO) circuit.

When the UPS is connected to this circuit, it enables

emergency shutdown of the UPS’s inverter and inhibits transfer

to internal bypass. Using the cable provided, connect the EPO

port of your UPS (see

) to a user-supplied normally closed or

normally open switch according to the circuit diagram (see

Note:

1. If using a cable other than what is supplied, the cable should not exceed

350 feet or have a resistance of greater than 10 ohms.

2. If a non-latching EPO switch is used, the EPO must be held for a minimum of

1 second. This does not apply to a latching EPO switch.

CAUTION: The EPO port is not a phone line surge

suppressor; do not connect a phone line to this port.

UPS Unit State when asserting EPO with AC line present:

LEDs Output Fans Serial SNMP USB LCD Screen

OFF OFF ON ON ON ON

“EMERGENCY

POWER OFF”

To restart the UPS unit after asserting EPO with AC line present:

Option 1:

1. Verify that the EPO assertion has been removed or cleared.

2. Press ON button until unit beeps, then release.

3. UPS output will turn back on after it completes diagnostics.

Option 2:

1. Verify that the EPO assertion has been removed or cleared.

2. Remove AC line power to the UPS unit, wait until the LCD is

completely off.

CAUTION: Do not open or mutilate batteries. Released material is harmful to the skin and eyes. It may be toxic. The following

precautions should be observed when working on batteries: Determine if the battery is inadvertently grounded. If inadvertently

grounded, remove the source from ground connection. Contact with any part of a grounded battery can result in electrical shock. The

likelihood of such a shock can be reduced if grounds are removed during installation and maintenance. (This is applicable to

equipment and remote battery supplies that do not have a grounded supply circuit.)

3. Reapply AC line power. Now the UPS will start back up in normal operation mode.

UPS Unit State when asserting EPO without AC line power:

LEDs Output Fans Serial SNMP USB LCD Screen

OFF OFF OFF OFF OFF OFF “EMERGENCY POWER OFF”

To restart the UPS unit after asserting EPO without AC line present:

1. Verify that the EPO assertion has been removed or cleared.

2. Reapply AC line power to the UPS unit. Now the UPS will start back up in normal operation mode.

External Battery Connection

Check the Unit Specific Accessories section under Overview for

compatible battery packs and maximum quantities for your UPS

system. Ensure that your battery pack matches the voltage

listed on your UPS battery connector. Adding external batteries

will increase recharge time as well as runtime. See the battery

pack owner’s manual for complete installation and setup

instructions. Make sure cables are fully inserted into their

connectors.Smallsparksmayresultduringbatteryconnection;

this is normal. Do not connect or disconnect battery packs when

the UPS is running on battery power.

IMPORTANT! To calibrate your UPS so that the runtime-

remaining LCD and software information screens

accurately predict runtime with external battery packs

connected, see page 23 for more information if connecting

external batteries to this UPS.
