Always On UPS Systems INSTALLATION - This bypass is intended for use in a controlled indoor environment free of conductive contaminants and protected against any type of intrusion. Do not install the bypass in an excessively humid environment or near water. Avoid spilling liquids and/or dropping any foreign object(s) onto the bypass. The unit must be placed in a sufficiently ventilated area; the ambient temperature should not exceed 40°C (104°F).
Always On UPS Systems THIS SAFETY NOTICE IS ADDRESSED TO THE ALWAYS ON CUSTOMER ENGINEERS WHO PERFORM MAINTENANCE OF THE UNINTERRUPTIBLE POWER SUPPLY (UPS) SYSTEMS. Electrical Safety • Maintenance work to be preformed by factory trained customer engineers, or qualified personnel. Extremely dangerous voltage levels can exist within the bypass system. Extreme caution must be used. • Ensure system is in maintenance bypass mode or external wrap-around bypass mode before work is started.
Always On UPS Systems 3. UNPACKING 3.1. Transport The bypass is packaged on a pallet, suitable for handling with a forklift. Pay strict attention to the center of gravity. The bypass must be moved in upright position. Do not tilt cabinets more than +/- 10° during handling. Move the bypass in its original package to the final destination site. Do not stack other packages on top. If the bypass must be lifted by crane, use suitable lifting straps and spreader bars. 3.2.
Always On UPS Systems 3.4. Site & Environment Consideration The designed function of the bypass cabinet is to allow the UPS system to be shutdown and removed from the circuit without power interruption to the load. Usually the life expectancy of the Bypass system is 8 to 10 years. The optimal life expectancy of the Bypass system can be achieved by careful consideration of the site and environment.
Always On UPS Systems h. Avoid accumulating litter or trash of any sort in or around the bypass system. The floor area surrounding the bypass should be kept clean, free from metallic powder and/or filings. i. Access to the bypass room should be limited to operation and maintenance personnel. The doors should be kept locked and the keys should be available only to authorized personnel. j. Personnel who operate or maintain the bypass system should be proficient in normal and emergency operational procedures.
Always On UPS Systems 3.6. Cable Selection The cabling of the bypass system has to be sized according to the UPS power rating. Sizing of circuit breakers, fuses and cables for input utility, output load and battery must meet the requirements of local and national electrical codes. WARNING Inadequate cable size and over sized breakers can increase the risk of fire or damage connection cables and internal components.
