Page 9: Introduction
2. INTRODUCTION Congratulations on your choice of the ZY120 uninterruptible power system (UPS), the UPS comes in nominal power ratings of 6000VA,10000VA and 20000VA. It is designed to provide conditioned power to microcomputers and other sensitive electronic equipment. When it is generated, alternating current is clean and stable. However, during transmission and distribution it may be subject to voltage sags, spikes and complete power failure that may interrupt computer operations, cause data loss and even damage equipment. - Page 10 SNMP card slot (option) Dry contactor slot USB port RS232 Parallel ports (option) Fans Reserved customer function External battery connector. 10.
