IMPORTANT SAFETY INSTRUCTIONS The M359 and its Battery Pack should not be tampered with by unauthorized personnel. Tampering with the M359 or its Battery Pack, or using them in any other way but their intended application, may result in a severe safety hazard. Disconnecting the input connector does not turn off the UPS. The unit should only be plugged into an approved, double-pole circuit breaker electrical outlet, rated between 32Amp (min) to 46Amp (max).
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. The high reliability and ruggedness of the M359 make it an excellent choice not only for military shipboard applications, but for critical shore-based applications as well. 1.2.
batteries. Please check your local regulations before disposal. The Battery Charger is a voltage-regulated and current-limited DC to DC converter. It is powered from the 270VDC output of the AC-to-DC LID Converter and provides temperature-compensated float charge to the Battery Pack. This charging method preserves the batteries and provides the longest batteries-life possible. The DC-to-AC Inverter generates clean sine-shape 115VAC voltage from the 270VDC output of the AC-to-DC LID Converter.

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). Verify that the electrical outlet that is powering the UPS is 115Vac/60Hz, protected by a double-pole circuit breaker (or fuses) rated to between 32 to 46Amp.

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.
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.
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. 5.3. Local Control (Using the Front Panel switches). If the M359 is controlled from its front panel switches, the remote ON/OFF switch should be in the On position and the remote UPS/BY-PASS selector in the UPS position.
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. 7.4 and Figure 10. 5.4.1. Remote PWR ON/OFF Switch. When in the Off position (down) this switch turns off the M359 (regardless of anything else).
(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. In this state, the ON BATT Warning yellow LED (16) will start blinking, warning the user that the UPS is working on Battery power. 5.5.4.
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. 5.6.
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. LOAD SHUTDOWN LED will both be On. 5.7.1.

Output Voltage (100V/Div) Output Current (50Amp/Div) 3 Seconds Figure 8: Overload (3KW) Shutdown 5.8. UPS Response to Overtemperature Condition When the internal hot-spot temperature of the UPS exceeds a preset level (+940C), the yellow O. TEMP Warning LED (23) will start blinking and an audible alarm will sound at one second intervals, 50% duty cycle. Three minutes after the O. TEMP Warning LED starts blinking (and if the temperature does not drop), the UPS will shut itself off.
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%. If Battery Test is denied due to low charge level ( when the BATT TEST Pushbutton is pressed) the BATT CHARGE Level Bar Graph will blink once.
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. Limiting the operating time on battery power, to the minimum required by the system to perform an orderly shutdown, will prolong Battery life. 6.3.
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: 1) Open the three captive screws (3, 9 and 10) holding the Air Filter. 2) Remove the Air Filter Assembly (as is, no need for further disassembly). 3) Wash the assembly with warm water and detergent. 4) Using dry air, remove water residue and dry the filter.

7.3. RS-232 Serial Interface The RS-232 serial communication interface is available through connector J5 (34), a D-Type 9S connector, located on the back panel of the UPS. This port is a DTE. Note: When the Optional Ethernet SNMP Agent is installed, this connector serves as RS-232 Console Interface and has different pin assignments (see the SNMP User’s Manual). The RS-232 interface allows control and monitoring of the UPS by a host computer through the serial RS-232 communication link.
The remote switches should be rated to 28Vac, 0.25AMP. Note: To control the UPS by the remote switches, leave all the front panel switches in the upper position. Turn the UPS On/Off by connecting/disconnecting Pin 8 to the Common. Select the operation mode (UPS or By-Pass) by toggling the Common between Pin 6 and 7. (See Figure 9 below).
8. Specification INPUT Voltage Range 0 - 155VAC In Accordance with MIL-STD-1399 (Navy) Switchover Voltage <102VAC, below this voltage the M359 may switch to Battery power.
