UPS should be completely turned off, otherwise there might be a danger of electric shock because output terminal might be still electrified. 3 . Please use PowerWalker specified appendix devices and accessories. Battery Safety 1 . Battery service lifetime will be shortened as ambient temperature rises. Replace batter- ies periodically to guarantee normal UPS performance and sufficient back-up time.

3 . Replacement of accumulator batteries requires a match of same type and model with equal quantity. 4 . As accumulator batteries may contain potential electric shock and short-circuit current danger, to avoid accidents that might be thus resulted, the following warnings should be observed during battery replacement: A .
PowerWalker VFI 3/3 Series products are also capable of ECO mode. Under ECO mode, UPS is powered by AC supply while in case of abnormal AC supply UPS will be sup- plied by accumulator battery after conversion through inverter.

4.2 Parallel machine operation 1. Redundancy introduction N+X is currently the most reliable power supply structure, in which N indicates the mini- mum UPS number required for the total load and X is the redundant UPS number, namely, the malfunctioning UPS number that the system can simultaneously bear. The larger X is, the higher reliability of system will be.
