Page 4: 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 5: General Description
-- as well as major blackouts -- protection must be constant and instantaneous. 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 6 The microcontroller follows a unique algorithm by which it regulates the charging process and enables a minimal recharging time. YOUR INVESTMENT IN MESTA'S TRULY UNINTERRUPTIBLE POWER SUPPLY INSURES THE VALUABLE POWER PROTECTION YOU NEED.

Page 7: 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 an environment with a temperature range of 0-40°C and relative humidity of 0-95%, without condensation. The site should not be excessively dusty or dirty. - Page 8 If your UPS is capable of 208/240 input voltage, the voltage that the UPS is set up for is printed on a sticker at the input plug. If you wish to change to the other voltage, Mesta has provided a procedure for qualified personnel to make such a change using only a medium, flat blade screwdriver.
- Page 9 Alternate Voltage Stickers: Shipped with your unit are alternate voltage stickers to be used if you change the input or output voltage of you UPS. If you change the input voltage, take the new input voltage sticker and place it over the one at the input plug of the UPS. If you change the output voltage, take the new output voltage sticker and place it over the one at the output receptacle at the back of the UPS.

Page 10: Operating Procedure
SYSTEM TURN-ON (REFER TO APPENDIX C FOR OPTION A) Once plugged in and turned on, the MESTA UPS will begin supplying power to the load. The green "AC LINE" and "BATTERY" lights will be on. If the AC line fails, the red "UPS" light will come on, and after 5 seconds an intermittent alarm will sound for 30 seconds. -
Page 11: Rs232 Interface
Mesta provides this software on a 51/4" or 31/2" diskette. Once communication has been established with the UPS, the UPS will provide a ">" prompt, which signals the operator to enter a command. -
Page 12: Table 1: Ups Software Parameters
None Parameters A through L displayed all at once Notes on the MESTA UPS Parameters: 1. The accuracy of the percentage of battery charge remaining depends on operating conditions and the present loading of the UPS. The accuracy will be much more precise at the lower percentages than it is at the higher percentages (where the performance curve flattens and a perfectly correct interpolation is more difficult - in the 92-100% range). -

Page 18: Figure 1: Ups Battery Tray Configuration
After the battery tray is removed from the cabinet, individual batteries may be disconnected and replaced, or the entire tray of batteries may be replaced. Exercise extreme caution to insure that batteries are replaced correctly, insuring proper battery polarities (consult figure 1 for correct wiring). Batteries must be secured back onto the tray using methods similar to the strapping and fasteners originally supplied. -
