The communications port is a standard DB9 female with both RS232 and simulated contact

closure capability. The Enterprise series units will poll the port and activate the port for

RS232 or contact closure in accordance with the type of cable it finds connected to the

port. To change the port configuration requires the unit be turned off and restarted with the

desired cable connected. The pinout for the port is depicted per the chart below.

Pin 1: Instant off ( pull and hold this pin low to turn off output receptacles)

Pin 2: /TXD

Pin 3: /RXD and receive ups shutdown command

Pin 4: Simulated contact closure AC fail, NO

Pin 5: Ground

Pin 6: Simulated contact closure low battery warning, NO

Pin 7: Simulated contact closure AC fail, NC

Pin 8: AC fail signal (high to low signal)

Pin 9: Not Used

COMMUNICATIONS PORT

ALARMS

ON BATTERY

When the UPS is operating on the batteries, the On-Line LED will blink and the audible alarm

will sound every 10 seconds. The alarm will stop once the UPS returns to On-Line operation.

UPS FAULT

When the UPS detects a hardware fault, the Fault LED will illuminate and the UPS will emit a

sustained tone. The fault condition can be reset by turning the UPS OFF and then ON. (see

section 5 Troubleshooting)

OVERLOAD

When the amount of load attached to the UPS exceeds its power rating, the Overload LED

will illuminate and the UPS will emit a sustained tone. This alarm will remain on until the

excess load is removed or the UPS’s self protection circuit shuts the UPS down.

REPLACE BATTERY

The UPS automatically tests the battery’s condition and will illuminate the Weak/Bad Battery

LED and emit a short beep. This tone will be repeated every hour until the batteries passes a

self test. It is recommended that the UPS be allowed to charge overnight before performing a

battery test to confirm a Weak/Bad Battery condition.

LOW BATTERY WARNING

The UPS will emit two consecutive beeps every five seconds when the battery reserve

runs low. This continues until AC returns or the UPS shuts down from battery exhaustion.

DIP SWITCH SETTINGS

The DIP Switch setting may be changed by the user to set the desired inverter (on battery)

output voltage. The DIP Switch must be set to the desired output voltage and then the unit

must be turned OFF and restarted to reconfigure the microprocessor and save the change.

The setting for the 117Vac units may be 108Vac, 113Vac, or 117Vac. This setting will

adjust the inverter (on battery) output voltage only. The setting for the 225Vac units maybe

215Vac, 225Vac, and 235Vac. All 208Vac applications should be set on 215Vac setting.

Switch #1 Switch #2 Output Voltage in battery mode

OFF OFF 108Vac (215Vac)

OFF ON 108Vac (215Vac)

ON OFF 113Vac (225Vac)

ON ON 117Vac (235Vac)
