    32Amp (min) to 46Amp (max). Note: If the available source can not support 32Amp, consider using the Special Option Unit (see MPS Doc: M359-1-1-X_SP). The M359 contains an internal high-voltage (132VDC), high-energy battery and large high voltage (270VDC) capacitors.

  • Page 4: General Description

    1. General Description 1.1. Intended Applications The M359 is a high quality, rugged, 2.0kW/2.2kVA, 19” rack-mounted, Uninterruptible Power Supply (UPS). It fully complies with all the requirements of MIL-STD-1399 (Section 300) and is specifically designed to meet the harsh military shipboard environment.

    2. Electrical Installation Instructions Before installing the unit, please read carefully the Safety Instructions at the beginning of this manual. Make sure that all the switches on the M359 front panel are in the OFF position. Verify that the Plug-in Battery Pack is properly installed and secured (see Paragraph 6.3).

    5. Operating the M359 5.1. General The UPS will not turn-on with Battery power alone. Therefore, to enable a UPS turn-on, AC Input must be presented at the UPS Input connector J1 and the Input UPS/By-Pass switch must be in the UPS position. If the Remote Switches function is not used, please verify that a mating connector is plugged into J4 (on the rear panel of the Unit) and that it has two jumpers: one between Pin 8 to Pin 4 and the other between Pin 5 to Pin 6.

  • Page 13: Off State

    5.2.2. Off State. When the M359 is OFF, the Input, the By-pass and the Output relays (see Figure 1) are not energized and are in the position shown on Figure 1. In this mode all of the UPS circuits are off and no power is presented on the AC Output connector J2. Please note that since the Input relay is located on the secondary side of the Isolation Transformer (see Figure 1), the Power Conditioner’s Input is always connected to the AC input on J1.

  • Page 14: Local Control (Using The Front Panel Switches)

    disconnected from the UPS input and the M359 is forced to operate from the internal battery (thus simulating an AC input failure). In this mode, the INPUT FAIL red LED (17) should be on, the ON BATT yellow LED (16) should blink, the OUTPUT OK green LED (21) should remain on, and the Bar-graphs should indicate the Load and Battery charge level.

  • Page 15: Remote Control (Using The Remote Switches)

    5.4. Remote Control (Using the Remote Switches). In order to control the M359 by the remote switches (via the connector J4 on the rear panel), the three front panel switches (2, 7 and 8) should be in the upper position. The recommended connection of the remote switches is described in Para.
  • Page 16 If the AC output is not available because of an external over-load or any other failure (external or internal to the M359) the OUTPUT FAIL red LED will be on. When in the By-Pass mode, all LED’s are off. 5.5.3. ON BATT Warning LED (16) When the M359 is operating in the UPS Mode and the AC Input fails, the UPS will use the Battery power as its primary source.

    5.5.11. BATT CHARGE [%] Bar-Graph (29). The Battery Charge Bar Graph indicates the charge level of the battery. 100% signifies that the battery is fully charged and will support 5 minutes at 2KW, 50% signifies 2.5 minutes at 2KW. Lower loads will result in longer hold-up time. When the Battery Charger is charging the Battery, the uppermost active segment of the Battery Charge Bar Graph will blink.

  • Page 18: Ups Response To Overload Condition

    5.7. UPS Response to Overload Condition The M359 has two distinct overload protection functions. The first is the linear (continuous) current limiting of the output current and other is an overload protection that shuts down the UPS Output if the output power (in watts) is exceeded. In case of a shutdown due to an overload, the green OUTPUT OK LED (21) will turn off and the red OUTPUT FAIL LED (19) and the red O.

    6. Maintaining the M359 6.1. Battery Test To test the Battery, press momentarily on the BATT TEST Push-button (26). Battery Test may be invoked only when all the following conditions are true: the UPS is running on AC input power, the Battery Charge level is above 85% and the load level is above 35%.

  • Page 22: Replacing The Battery Pack

    6.2.3. Charge-discharge Cycles The number of times and the depth of battery discharges (during AC Input failure) affects the service life of the battery. If the battery is allowed to discharge only to 50% of its charge, the number of charge-discharge cycles (before it fails) will be three times the number of cycles had it been allowed to reach 30% charge.

  • Page 23: Air Filter Maintenance

    6.4. Air Filter Maintenance The Air Filter (4) should be monitored periodically for cleanness. Dust and dirt accumulation can interfere with the cooling air-flow and may result in over temperature condition. To clean the filter: Open the three captive screws (3, 9 and 10) holding the Air Filter. Remove the Air Filter Assembly (as is, no need for further disassembly).
  • Page 24 Standby Mode (Ac output is off, all other functions are on.) Note: for Special Option Units M359-1-X-2 this pin has different function (see MPS Doc M359-1-X-2_SP). When the UPS operates on battery power, Pin 9 will be shorted to Pin 5 and pin 4 will be open.
