3.6.8.1.12Press and hold the On Switch (on the front panel of the UPS) for approximately 3-seconds, then release. The audible alarm will sound 2- beeps. The UPS will perform its normal startup test. Once the startup is complete the UPS will be in the normal On-Line mode.

NOTE: If the Maintenance Bypass Procedure is not followed in the correct order and step-by-step the UPS and/or the connected equipment could be damaged.

4 Communication Port, EPO Port and Option Cards

4.2.EPO (Emergency Power Off) Port

Connect one end of a two-wire cable to the EPO port and the other end of the two-wire cable to an EPO switch, and then short pin1 to pin2 for approximately 1.0-second to shutdown the UPS in the AC or the Battery mode. The LCD display will display EPO and Line OFF every 6-seconds. The UPS must be turned off and then turned back on again to restart the UPS. Connecting to the EPO port is optional the UPS system operates properly without this connection.

AC Mode Operation:

While the UPS is in the normal AC mode apply the short to pin1 and pin2 for approximately 1.0-second. The UPS shuts down, the fans will still be on. In approximately 1-minute the fans will reduce speed.

To restart the UPS: Press the Off switch on the front panel for 2-beeps then release. Turn the UPS’s input circuit breaker (on the rear panel) to the Off position. Wait for approximately 1-minute (until the fans turn off) then turn the input circuit breaker to the On position. The UPS will be in the Bypass mode. Press the On switch on the front panel for 2-beeps to turn the UPS on.

DC Mode Operation:

While the UPS is in the DC mode apply the short to pin1 and pin2 for approximately 1.0-second. The UPS shuts down, the fans will still be on. In approximately 1-minute the fans will reduce speed.

To restart the UPS once the utility power returns: Press the Off switch on the front panel for 2-beeps then release. Turn the UPS’s input circuit breaker (on the rear panel) to the Off position. Wait for approximately 1-minute (until the fans turn off) then turn the input circuit breaker to the On position. The UPS will be in the Bypass mode. Press the On switch on the front panel for 2- beeps to turn the UPS on.

4.3.Option Cards

The optional interfaces cards are ED6/10KVA Programmable Relay Card (Dry Contact Relay) and the SNMP card. When the option cards are used in conjunction with RS232 communications port on the rear panel, the shutdown command from the EPO port will get the highest priority for the control command, then the RS232 port, then the SNMP card, and then the ED6/10KVA Programmable Relay card gets the lowest priority. Also there is ENV PROBE for environmental monitoring.

5 Power Monitoring Software

The SentryPlus software that comes with the UPS is compatible with many operating systems such as Windows NT/2000/XP/2003, Red Hat Linux, Fedora Linux, SuSE Linux, and FreeBSD.

5.1.Hardware Installation

5.1.1Connect one end of the RS232 cable to the UPS communication port.

5.1.2Connect the other end of the cable to the RS232 port on the computer.

5.2.Software Installation

5.2.1Refer to the software user’s manual on the software CD.
