Installation Procedure 1.4 TCE connections to MSS 2000/3000/4000/5000A Cabinet version of MSS 2000/3000/4000/5000A is provided with already assembled and installed TCE. These cabinets are factory fitted and already connected as per customer request (input right/output left or, vice versa, input left/output right). In case it is necessary to disconnect and re-connect TCE before the installation in field, it is necessary to disassemble and then re-assemble both mechanical and electrical connections.
Installation Procedure 1.5 Input Current Measurement and Backfeed Protection The Backfeed protection is already installed and properly connected on all the versions of MSS 1000A. On MSS 2000/3000/4000/5000A cabinet version, the Backfeed protection is already installed and properly connected depending on customer’s requests. The harness is properly routed to the internal connections on MSS basing on the request to have the input TCE cabinet on the left or on the right.

Electrical Installation ELECTRICAL INSTALLATION The Multi-Module MSS System requires both power and signal cabling once it has been mechanically installed. All signal cables, whether screened or not, should be run separately from the power cables in metal conduits or metal ducts which are electrically bonded to the metalwork of the cabinets to which they are connected.
For external wiring requirements refer to the local regulations for the selection of the proper conductor sizes. See Table 4 for nominal currents and determining the size of MSS power cables. The power cable must be selected according also to specific application environment. Table 4 - Power cable specification Size 1000A 2000A 3000A 4000A 5000A...
V1 W Gland plate cable entry from the bottom Figure 2-2 - MSS 1000A - front drawing without panels 2. Connect PE first. 3. Route power cables into the cabinet. 4. Connect parallel control cable as per paragraph 2.3. 5. Connect bypass reference cable as per paragraph 2.3.2.
Electrical Installation 2.1.5 Power Cable Connection Steps of MSS 2000/3000/4000/5000A with TCE Cabinets When selecting the power cables for side entry to a module located on a solid floor, consideration must be given to the minimum permissible radius of the proposed cables to ensure that they can be fashioned to reach the MSS connection busbars.
Electrical Installation 2.1.6 Earth Protection WARNING FAILURE TO FOLLOW ADEQUATE EARTHING PROCEDURES CAN RESULT IN ELECTRIC SHOCK HAZARD TO PERSONNEL, OR THE RISK OF FIRE, SHOULD AN EARTH FAULT OCCUR. CONNECTION OF THE EARTH CABLE AND THE NEUTRAL WIRE MUST COMPLY WITH APPLICABLE LOCAL AND NATIONAL REGULATIONS.
Electrical Installation However, if the bypass lines lead from sources that are electrically isolated from each other, a differential protection device may be installed on each line. In this case, and in cases when the load is supplied from the bypass via the Static Bypass Switch, the isolated sources are connected in parallel.
This slot is the reserved interface for the LIFE modem card. This card provides an independent, external modem interface for communication with the LIFE service station. Ask your local Vertiv dealer for more details on LIFE and its benefits for your UPS system. When a LIFE modem card is inserted into XS6, interface XP6 is connected to the XS6 slot to allow the parameterization and diagnosis of the LIFE modem card.
Electrical Installation 2.2.8 XP10 - EPO Connector In a multiple devices system made of MSS and several UPS, each device must receive EPO towards a dedicated contact. EPO inputs can’t be connected in parallel. Connection with customer plant: 7-wire connector with screw terminals and screws for fixing it. Connection should be as follows: Figure 2-5 - Connection of the connector XP10 The Emergency Stop action shuts down the rectifier, inverter, and static bypass.
Electrical Installation This selection is preferred when the load power have priority against the EPO effective function. In case of emergency other devices will act and insulate the load if required. When the customer selects the OR function, UPS will enter EPO condition when one of the two inputs (or both) will activate. This happens when one of the two lines is in short circuit and the other is functioning properly.
Electrical Installation 2.2.10 XP11 - Input Connector Connection with customer plant: 12-wire connector used for dry contacts, only safe operating voltage will be connected here. Type (MCV 1.5/12-G-3.81) by PHOENIX contacts or equivalent. Complementary type (MC 1.5/12-ST-3.81) will be included. The current range of the contacts at 24V is 1A.

WARNING: Output CT can generate hazardous voltage when disconnected from the boards or screw terminals.
Operating Principle OPERATING PRINCIPLE Through the intelligent control of the static switch (from MSS + TCE cabinets) containing the controllable electronic switch, the loads can be powered by the inverter output of the centralized parallel system or the bypass of MSS. In normal operation, the loads are powered by the inverter output of the MSS parallel system, in which case the MOB switch is closed.
Operating Principle 3.1.2 RMS Overload Control Logic With load supplied by the MSS, MSS Overload control transfers the load to bypass as soon as all the MSSs set the Inverter Overload warning. The commutation takes place by forcing the Intelligent ECO Mode to the MSS parallel system (Rectifier ON, Inverter Tuning ON).
Operation OPERATION This chapter introduces the operating precautions and daily operating methods of the centralized parallel system in detail, including the start-up, shutdown and transfer of the UPS and the MSS bypass cabinet. First, you must ensure that the UPS and the MSS bypass cabinet have been completely installed and tested by the engineer.
Page 55
Operation Power Supply Switches Power supply switch of the MSS bypass cabinet For 1000/2000/3000/4000/5000A MSS, all the power switches (or CBs) are outside the cabinet. The power supply switches in the UPS can be seen by opening the front door with a key. Figure 4-1 shows the positions of the following power switches.
Operation 4.1 Start-up These procedures are applicable to start-up of the centralized parallel system in total power-down state, which means the centralized parallel system or the maintenance bypass has not supplied the load before. The assumption is that the UPSs are configured, the MSS bypass cabinet has been completely installed and tested by the engineer, and the external power supply switch is closed.
NOTE IF THERE IS AN ALARM MESSAGE DURING POWER-ON, PROCESS THE FAULT ACCORDING TO THE USER MANUAL FOR 80-eXL/EXL S1 ALARMS TABLE, OR CONSULT THE LOCAL VERTIV CUSTOMER SERVICE CENTER. 4.1.2 Starting up the Centralized Parallel System Operating in MSS Normal Mode and Transfer to UPS 1.
Operation 5. Check whether there is an abnormal alarm in the current window. Confirm that the power flow diagram displayed on the MSS LCD is the same as in Figure 4-5; the centralized parallel system is supplied by the UPS line. Figure 4-5 4.2 Shutting down UPS If you want to shut down the centralized parallel system supplied by UPS, follow this procedure.
Operation Figure 4-7 2. This operation will stop the UPSs inverter and the centralized parallel system supply power to load through the static bypass of the MSS bypass cabinet. 3. The power flow diagram on LCD screen will be as shown in Figure 4-8. Figure 4-8 4.
If one of the fuses associated with the individual SCR is blown, the MSS will detect the fault and display the corresponding message on the control panel. All three phases are monitored in this way. 1. These fuses are fitted as standard on the 1000A version. 2. Select fuses according to the MSS rating, see table below: MSS RATING...
