Option 3—USB Communications a. Connect USB cable provided with the UPS to the USB ports on the S2K and your computer. The S2K will work automatically with your built-in power management software on Windows XP and 2000 and Mac OS 10.2 or later (see USB Interface Port section for details).
ONTROLS AND NDICATORS ON/OFF/Alarm Silence Button This button controls output power to the connected load and has three functions: • ON • OFF • Alarm Silence ON/OFF/Alarm Silence When the UPS is off, pressing and releasing the main ON/ OFF button will start the UPS, and an audible alarm sounds briefly.
Status Indicators: Mains, Battery, Fault There are three (3) status indicators on the front of the UPS (Mains, Battery and Fault), as shown in the diagram below. Each indicator illuminates to specify the status of the UPS (see Troubleshooting section for details). Mains Indicator (Green/Amber) The Mains Indicator illuminates when the UPS is operating and sup- plying power to connected loads: green indicates Normal mode, amber...
Transfer Voltage Selectors (DIP Switches) DIP Switches Rear of UPS The two-position DIP switch control on the rear panel, shown above, allows the operator to select the mains transfer voltage at which the UPS will switch to battery power. DIP switch positions for each volt- age setting are as follows: DIP switch settings Left...
When the UPS is in Normal mode, the Mains Indicator illuminates green. Mains Indicator (Green) The S2K unit continuously monitors the batteries to maintain them in a fully charged state. The battery charger operates whenever AC power is present, even if the UPS is switched off. By default, the UPS is set to perform an automatic battery test after it has been operating continuously for two (2) weeks.
Battery Mode The UPS switches to Battery mode in the event of an extreme voltage/ frequency condition or complete mains failure. The battery system supplies power through the Bi-Directional Converter to generate power for connected equipment. When the UPS is in Battery mode, the Battery Indicator illuminates green and an alarm sounds every 10 seconds.
OMMUNICATIONS DB-9 Connector The UPS has a DB-9 (9 pin female) connector on the rear to allow UPS status communications with a computer system running MultiLink™ software. The DB-9 is capable of supplying serial communication, on battery and low battery signals. MultiLink, UPS monitoring and shut- down software, is shipped with the UPS, along with a 3m (10 ft.) DB-9 cable required for running MultiLink.
Remote Shutdown Via the DB-9 Connector The S2K unit can be shut down remotely by shorting Pins 5 and 6 or via Pins 4 and 5 of the DB-9 connector. Shutdown Via Pins 5 & 6 When Pin 6 is shorted to Pin 5, the UPS output is shut off regardless of what mode the UPS is operating in.
AINTENANCE The Sola S2K UPS requires very little maintenance. Follow these practices to prevent problems. Cleaning the UPS The following will help ensure trouble-free operation for years: • Vacuum dust from the ventilation intake occasionally. • Wipe the cover periodically with a dry cloth.
Battery Replacement Procedure Replacement requires removing the battery cover plate on the back or bottom of the UPS. No tools are needed. To replace the batteries: 1. Remove the bat- Figure 1 Figure 2 tery cover plate on the back/bot- tom of the UPS (Figure 1).
ROUBLESHOOTING The information below indicates various symptoms a user may encounter in the event the S2K unit experiences a problem. Use this information to determine whether external factors caused the prob- lem. See Troubleshooting Chart for suggested remedy. 1. The Fault indicator illuminates, indicating the Mains UPS detected a problem.
Troubleshooting Chart If the UPS fails to operate properly, turn off the unit and repeat the steps in the Installation section of this manual. If the problem per- sists, refer to the chart below: Problem Cause Solution Check the circuit protector on the rear of the UPS.
