1 I MPORT A NT S AFETY I NSTRUCTIONS SAVE THESE INSTRUCTIONS This manual co ntains important ins tructions that shou ld be followe d during insta llation and mainte- nance of your Series 610 UPS and batteries. ! WARNING Exercise extreme care when hand ling UPS cabi nets to avoid equipment damage or i njury to personnel.
Introd uction 2 1.0 I NTRODUCTION 1.1 System Description The role of the parallel-redundan t multi-module UPS system is to supply uni nterruptible, clean power to the critical load. The UPS maintains a full -voltage, low -distortion outp ut, even if the ut ility source power sags, becomes distorted or fails.
Introd uction 3 In the unlikely event of a fault wi thin the UPS, the SCC control logic, which continuously monitors all critical circuits within the UPS system, transfers the load to bypa ss without interruption and simul- taneously activates local and remote al arms.
Introd uction 4 Figure 3 System Control Cabinet s T ypes of System Control Cabinet s (SCCs) • SCCT —A stand-alone cabi net containing system contro l logic for up t o six UPS modules, a sta tic bypass switch, manual ly operated disconnects for the stat ic bypass switch and two motor-oper- ated system circuit breakers.
Introd uction 5 Other Factors to Consider Reliability depends on more than just UPS module desig n. Improper installa tion can cause any sys- tem to fail.
Introd uction 6 1.4.3 Recharge After the utility source power is re stored or an alternate power source becomes available, each recti- fier/charger slowly walks-in to once agai n power the inverters and recharge the battery plant .
