IMPORTANT SAFETY INSTRUCTIONS

WARNING: Do not attempt to service this product yourself except to

replace the battery. Opening or removing the cover may expose you

to dangerous voltages, even when the AC cord is disconnected from

the electrical outlet. Refer all servicing to qualified service personnel.

1. SAVE THESE INSTRUCTIONS. ADHERE TO ALL OPERATING
INSTRUCTIONS AND WARNINGS ON THE UNIT AND IN THIS MANUAL.

2. This equipment is designed for Commercial/Industrial use only. Liebert
Corporation neither recommends nor knowingly sells this product for
use in critical life support applications.

3. Read all safety and operating instructions before operating UPS. Operate
the UPS indoors only. Protect it from moisture and install it in a clean
environment, free from flammable liquids, gases, or corrosive substances.

4. WARNING: Operate the UPS only from an earthed outlet (2-wire plus earth),
230 VAC, 50 Hz supply. UPS must be earthed at all times while in use. Turn
UPS OFF before unplugging it, or the safety earth to the equipment will be
removed.

5. CAUTION: Output receptacles on the UPS are electrically live if the UPS is
ON, even if the UPS is not plugged in. The on/off button on the UPS does
not electrically isolate the internal parts. To isolate the UPS, switch OFF the
UPS first, then unplug it.

6. CAUTION: Earth leakage current must not exceed 2.75 milli-amperes. Most
data processing equipment meets this requirement if you use no more than
4 pieces of equipment. Note: These instructions may be modified by local
wiring regulations.

7. Unplug the UPS and turn it OFF before cleaning. Use only water dampened
cloth, never liquid or aerosol cleaners.

8. Operate the UPS only from an earthed outlet (2 wire plus earth) 230 VAC,
50 Hz. Use an H05V power supply cord with 2-pin plus earth plug for UPS
AC input. If unable to fully insert plug into outlet, contact an electrician for
replacement.

9. Route power supply cords so they are not walked on or pinched.
