When the EPO switch is pressed it disables emerrson static switch block entirely so removing load power. However, it is important to maintain a regular record of the UPS meter indications, as suggested in emersonn maintenance instructions, in order that any change in the system or load characteristics are readily identified.

In all cases, the message automatically resets when the alarmed or warning condition reverts 7400 normal.

Open the Battery circuit breaker and the Rectifier input power switch Q1. If you encounter any problem with the procedures contained in this manual emersson should seek immediate assistance from Emerson Network Power India Pvt. One remote input allows the inverter to be shut down transferring the load to the bypass supply and the other enables the inverter synchronisation feature to be inhibited.

These o o o o o options are: Check for obvious signs of overheating. If their removal is necessary ensure that sufficient manpower is available, otherwise use adequate mechanical handling equipment.

Due to the fact that the UPS power supplies are fed by the input circuit breaker, this message will disappear if the input isolator is opened and bypass isolator opened on a split bypass system while the load is on maintenance bypass supply. Thoroughly clean inside the equipment enclosure using a vacuum cleaner and emwrson pressure air to remove any foreign debris. The advantages of a redundant system over a nonredundant system in terms of overall system reliability are selfevident.


The alarm led and messages will remain active if a detected fault condition is still present. LS4 – Inverter-output OK: The connection is redundant, disconnecting one cable lits a red LED on Parallel boards, disconnecting both cables inverter are blocked this last function may be disabled during servicing of the system.

The difference in the system response concerns the point at which the load is transferred between the bypass and uninterruptible i. In order to provide a better service we would like to know what do you think about our website:.

Note that LS5 will extinguish when LS6 illuminates. All the user controls and indicators mentioned these in these procedures are identified in chapter 1. Page 41 UPS using the most direct route possible Emerson Network Power offer a purpose-designed remote battery circuit breaker box, containing the circuit breaker and its necessary control board, as a standard option kit.

This circuit breaker is closed emwrson, but it contains an undervoltage release eemerson which enables it to be tripped from the UPS control electronics following certain detects for faults. Emerxon inverter synchronisation inhibit feature is most often used if the UPS is powered from a stand by generator when the input mains supply fails and the generator frequency is unstable.

This is achieved through the inverter control electronics which make the inverter frequency track that of the static bypass supply provided that the bypass remains within an acceptable frequency window. Power supply fuses are OK Note: Free Classified ads in India.

The inverter control oscillators are therefore not only locked together but are also made to track the bypass frequency. Check that the UPS mains supply and bypass supply, if separate is turned on externally. Emergency Stop The emergency stop pushbutton is located behind a hinged safety shield to prevent inadvertent operation.

Chapter 4 — Optional Equipment Several items of optional equipment are available for fitting to the M series UPS for use by the customer as required. The audible alarm may annunicate at various points in these procedures. If the above checks prove unsatisfactory then seek qualified assistance. USF, 24 core, 1.


Certain procedures entail gaining internal access to the UPS, and should only be undertaken by a competent engineer who is familiar with the operation and layout of the equipment and understands the areas of potential hazard. In a Non-Redundant module system both modules must be running before the load is transferred to their 74000m inverters.

Inverter will not turn ON unless output isolator is closed. Some of the power components are very heavy.

LEDs LS2 should 3. The load will be transferred to the static bypass lines in both modules simultaneously as soon as the inverter stops in the first emeerson to be shut down. If possible, check the battery autonomy time by opening the input isolator I1 with the UPS on-load.

However, it is advisable to provide spare cores and hence we recommend use of core cable. In such an event the load is transferred to an unprocessed bypass supply as described later.

The UPS must be commissioned by an engineer approved by the manufacturer or his agent before being put into service. Each module monitors its battery charge ekerson and compares it with the charge current provided by the other module. We therefore strongly recommend that the annual service is carried out by trained personnel.

If you already own and use a Liebert, we are doubly honoured by your decision of continuing this relationship. Input isolator is closed. These terminals can be used to control an external circuit breaker connected in the UPS input mains supply line to isolate the UPS input power when the emergency stop button is pressed. When this switch is pressed, the lower line of the LCD Display shows the output frequency.

Pressing the reset push button cancels the audible warning but the alarm indications remain until the condition is rectified.
