Always On UPS Systems 2. IMPORTANT SAFETY INSTRUCTIONS READ AND FOLLOW ALL SAFETY INSTRUCTIONS. SAVE THESE INSTRUCTIONS. This manual contains important safety instructions that should be followed during installation and maintenance of the N Series DC UPS system and optional packages.
Always On UPS Systems INSTALLATION - This DC UPS is intended for use in a controlled indoor environment free of conductive contaminants and protected against any type of intrusion. Do not install the DC UPS in an excessively humid environment or near water. Avoid spilling liquids and/or dropping any foreign object(s) onto the DC UPS. 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 DC UPS system. Extreme caution must be used. • Ensure system is in maintenance DC UPS mode or external wrap-around DC UPS mode before work is started.
Always On UPS Systems 3. UNPACKING 3.1. Transport The DC UPS is packaged on a pallet, suitable for handling with a forklift. Pay strict attention to the center of gravity. The DC UPS must be moved in upright position. Do not tilt cabinets more than +/- 10° during handling. Move the DC UPS in its original package to the final destination site. Do not stack other packages on top. If the DC UPS must be lifted by crane, use suitable lifting straps and spreader bars. 3.2.
Always On UPS Systems 3.3. Storage STORAGE OF THE DC UPS The DC UPS is carefully packed for transport and storage. Never leave a DC UPS outside the building exposed to the elements and do not place other packages on the top of the DC UPS. Storing: It is recommended to store the DC UPS in its original package in a dry, dust-free room, away from chemical substances, and with a temperature range of -25°C (-13°F) to 55°C (131°F). Exceeding this temperature range may cause damage.
Always On UPS Systems 3.4. Site & Environment Consideration Usually the life expectancy of the DC UPS system is 8 to 10 years. The optimal life expectancy of the DC UPS system can be achieved by careful consideration of the site and environment. The following precautions and recommendations should be checked when considering the site and environment for the DC UPS: a. The DC UPS should be located in a place with adequate ventilation (refer to the specification of the heat dissipation of the DC UPS).
Always On UPS Systems h. Avoid accumulating litter or trash of any sort in or around the DC UPS system. The floor area surrounding the DC UPS should be kept clean, free from metallic powder and/or filings. i. Access to the DC UPS 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 DC UPS system should be proficient in normal and emergency operational procedures.
Always On UPS Systems 3.6. Cable Selection The cabling of the DC UPS 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. M1306_GES-242NX-R Operators and Install Manual V1.

Always On UPS Systems A: Metering- The GES-242N-R incorporates 4 digital displays for the user to monitor their Voltages and Currents. 1. Input AC voltage: Detects the input AC, allowing the user to monitor the 480 VAC required to power the UPS. 2. Battery Current: This ammeter detects both charge and discharge current of the batteries. The ammeter has a range of +/- 200 ADC. 3. DC Output Voltage: Detects the DC output voltage supplied to the Load. 4.
Always On UPS Systems C. Rectifier LED: This LED is lit when the rectifier is operating, the supply is within operating parameters, and the input breaker is closed. D. Output LED: This LED is lit when there is DC power present at the output terminals. E: Callback Switch: Is installed to allow the user to silence the buzzer when a fault arises while they are working on the unit.
Always On UPS Systems 10. RELAY CONTACTS AC FAULT: Tells the end user that no AC Voltage is present on the input of the DC UPS. FAULT: Is designed to inform the operator when the charger fails to deliver the necessary voltage to charge the batteries. It is also designed to inform the operator that one or both DC rectifiers have failed and that the DC UPS should be immediately shut down. LOW BATTERY: This alert is designed to inform the operator that the battery voltage is below 22.
