® 2. Operation The combination of these signals enables rapid and intuitive understanding of its operating status and recognition of any problems in the power supply. There are three main operating modes - Mains operation - Battery operation - By-pass operation 2.
2.6 Visual and acoustic warning signals Status indicator Acoustic signal Messages displayed Green - UPS on Mains IN xxxV Normal operation with mains present and loads within the set limits The UPS is indicating that the frequency of the output voltage is not synchronised with the input voltage. The cause of this may be: - PLL disabled - Frequency of the input voltage is outside the set limits for the UPS Description Green Fast flashing - UPS on Mains No sync mains xx.

® 3. Installation 3.7 Guide to using the diagnostics software 3.7.1 Connection Your UPS is fitted with a standard RS232 interface, which can be used in conjunction with a computer in order to access data relating to the operation of the UPS and its log. This function must be used together with the interface programme for WINDOWS environments available from our website www.ups.legrand.com without charge.
4. Customising the UPS operating mode 4.1 The functions of the buttons The buttons on the front panel of the UPS are used to access its various menus. Button Description - Exit a function without modifying it - Go up a level to an upper level menu - Exit the main menu and return to status display - Silence the buzzer - Select previous function - Increase a value within the function - Select a new item within the function (e.g.

Customising the UPS operating mode 4.5 UPS Setup Output Voltage Frequency N+x Redundancy ð Voltage To set the UPS output voltage (V) To set the UPS output frequency (Hz) Nominal Value: to set a numerical value for the output frequency (50 or 60) Frequency Auto Selection: If enabled, the UPS reads the frequency of the input voltage and then synchronises the output to the same value. If disabled, the UPS uses the set Nominal Value.
ATTENTION If the PLL function is disabled, the automatic by-pass function is also disabled. Should the variation in input frequency be above the set range, the UPS will inhibit the PLL function and release the output and input lock. When the range returns within the set threshold, the PLL function will be reinstated automatically. By-pass Bypass Enable Forced mode DIP Speed Off-line mode Load Wait Mode ð Bypass Enable If enabled, the UPS manages by-pass intervention automatically.
® 4. Customising the UPS operating mode Neutral Sensor Enable Ignore While Run ð Enable If enabled, the UPS uses the neutral sensor to verify that the difference in voltage between neutral and earth is within safety limits. Should it go above the threshold, the UPS will automatically switchover and run on battery mode. If disabled, the UPS will ignore the neutral sensor. Ignore While Run If enabled, the UPS only verifies neutral-earth voltage when it is switched on.
SIMPLE MODE Batteries Set capacity Battery Thresholds ð Set capacity Simple mode Sets the warning signal for the end of battery autonomy using the battery voltage. There are two possible settings in the Mode menu Battery thresholds If you select Mode – Automatic thresholds The UPS automatically calculates the voltage thresholds based on the load: the UPS will signal AUTONOMY RESERVE and END OF AUTONOMY, respectively, below these.

® 6. Troubleshooting Problems 30 Solutions When the UPS is switched on, the buzzer sounds and the red warning light makes alternating short-long flashes, then the UPS switches off after 15 seconds. The connection of the neutral conductor is wrong: invert the power supply plug, or invert the connections of the neutral and phase input leads, or exclude the neutral sensor. The UPS works but a short beep is heard every 12 seconds and the yellow warning light is lit without flashing.
