DO NOT PLUG THE UPS INTO EXTENSION CORDS, ADAPTER PLUGS, SURGE STRIPS, OR POWER STRIPS. Do not cut the input plug off and attempt to hardwire the UPS, as doing so will void the warranty.

Checking the Site Wiring Fault:

After plugging the UPS into the AC wall outlet, check the Site Wiring Fault (SWF) icon on the front panel. If the SWF icon is illuminated, the UPS is plugged into an improperly wired AC wall outlet. If the UPS indicates a Site Wiring Fault (SWF), have a Qualified Electrician correct the problem.

Charging the Battery:

The UPS will charge the internal batteries whenever it is connected to an AC source with an acceptable voltage (90-150VAC). It is recommended that the batteries be charged for a minimum of 4 hours before use. If the UPS is going to be stored for a prolonged period, the batteries must be recharged for at least twenty-four hours every ninety days.

The PARA SYSTEMS MINUTEMAN PRO-RT 2U PRO750RT2U uses audible alarms to alert you to different conditions:

• On Battery: When the UPS is operating on batteries, the audible alarm will sound one beep every 10 seconds. The AC mode icon will extinguish, and the On-Battery icon will illuminate.

• Low Battery Warning: When the batteries reach the predetermined low level (approximately two minutes of runtime remaining), the audible alarm will sound two beeps every five seconds. The LCD will display error code E07. This alarm cannot be silenced.

• Weak/Bad Battery: If the battery is weak, bad, or disconnected, the Weak/Bad Battery icon will illuminate, the LCD will display error code E06, and the audible alarm will sound three beeps every five minutes until the battery is reconnected or replaced.

• Overload: When the connected load exceeds the UPS’s power rating, the Overload icon will illuminate, the LCD will display error code E02, and the audible alarm will sound continuously in both AC and Battery modes. This alarm will remain on until the excess load is removed.

• UPS Fault: When the UPS detects an internal fault, the Fault icon will illuminate, an error code will be displayed, the audible alarm will sound continuously, and the output will be turned off. In some cases, this may be cleared by turning the UPS off and then on.

Load Shedding Function:

The output receptacles are electrically wired into two segments (labeled Load 1 & Load 2). You can control these two segments individually or both at the same time using the Power Monitoring Software or an SNMP card. This allows for non-critical loads to be shut down to preserve battery runtime for more critical equipment. The output segment labeled ‘Always On’ does not support the Load Shedding function.

Emergency Power Off (EPO) Function:

Connect one end of an RJ11 cable to the EPO port and the other end to an EPO switch. In either AC or Battery mode, shorting pin 4 to pin 5 for approximately 0.5 seconds will shut down the UPS. The UPS must be turned on to restart. The LCD screen will display ‘EPo’ when this function is active.
