Page 5: Introduction
1. INTRODUCTION Thank you for buying the Mesta Electronics UPS! You are now an owner of a TRULY UNINTERRUPTIBLE POWER SUPPLY. No other system on the market can match your UPS. SAVE THESE INSTRUCTIONS—This manual contains important instructions that should be followed during installation and maintenance of the UPS and its batteries.
Page 6: General Description
The Mesta UPS system provides this kind of comprehensive protection by maintaining a clean, well- regulated flow of power to critical loads, regardless of the quality of incoming AC line power. It remains in a constant state of readiness, so there is no time delay in compensating for AC line failures.
Page 7 The output neutral is internally connected to chassis ground in these units. This option results in a UPS that is slightly larger and slightly less efficient than standard models. YOUR INVESTMENT IN MESTA'S TRULY UNINTERRUPTIBLE POWER SUPPLY INSURES THE VALUABLE POWER PROTECTION YOU NEED.
Page 8: Installation
Again, in case of any damage, report it directly to the dealer or the carrier. Environment: The MESTA UPS is designed to be used in a temperature controlled, indoor area free of conductive contaminants, having a temperature range of 0–40°C and relative humidity of 0–95%, without condensation.
Page 9 Installation Complete: Assuming an overload doesn't occur prior to attaching and turning on all loads, you have completed the installation procedure of your UPS. From here on there is no special powering up or powering down sequence that needs to be followed for either your load equipment or the UPS.
Page 10: Operating Procedure
SYSTEM TURN-ON Once plugged in and turned on, the MESTA UPS will be supplying power to the load. The green "UPS On" light will be on solid, the green "On Line" light will be on solid and the yellow "On Battery"...
Page 11 Flashing with 10% duty cycle -- 2-9% charged. When batteries are discharged to below 10% level, solid audible tone is generated for 30 seconds or until "Alarm Reset" is pressed. (The level of the Low Battery alarm can be changed using the FSET Routine, section 5 RS232 Interface).
Page 12: Rs232 Interface
Mesta provides this software on a 5¼ " or 3½ " diskette. Once communication has been established with the UPS, the UPS will provide a ">" prompt, which signals the operator to enter a command.
Page 13: Table 1. Ups Software Parameters
None Parameters A through R displayed all at once Notes on the MESTA UPS Parameters: 1. Current draw from the batteries is "+" if batteries are being discharged and "-" if batteries are being charged. A small positive or negative value of .1 or .2 amps may not necessarily reflect that the batteries are being charged or discharged.
Page 14: Table 2: Rs232 Technical Specification Summary
For the Battery Alarms: • You will be prompted to choose from the modes of Enable (5-60 second annunciation duration or until manual reset with the Alarm Reset button), Disable (off - no audible annunciation) or Forever (continuous or until manual reset with the Alarm Reset button). •...
Page 15: Storage
6. STORAGE Battery Life: The MESTA UPS should be stored with the batteries fully charged. Storage temperature should be maintained between -20°C and 40°C. The life of the batteries may be greatly reduced if stored at temperatures exceeding 30°C for extended periods of time. Optimal storage temperature for maximum battery life is 20°C or lower.
Page 16: Internal Maintenance
Only qualified technicians or supervised personnel should open the UPS and only after ALL of the following WARNINGS and instructions are read and fully understood. Mesta's UPS has been designed to provide unprecedented reliability; therefore it requires little or no maintenance. However, should internal maintenance be required, please adhere to the following warnings and instructions.
