Overall Dimensions MC2KW Output Module: Width is 17-3/4 inches (45.09cm), Height us 12-5/16 inches (31.27cm) including feet, Depth is 26-5/ 8 inches (62.54cm) including the front panel, handles, knobs and interconnect cables2 MC2KW Power Module: Width is 17-3/4 inches (45.09cm), Height us 12-5/16 inches (31.27cm) including feet, Depth is 26-5/ 8 inches (62.54cm) including the front panel, handles and interconnect cables2 Weight MC2KW Output Module is 121 poulds (54.9kg) net, 146 pounds (66.2kg) in shipping carton MC2KW Power Module is 158 poulds (71.7kg) net, 183 pounds (83.0kg) in shipping carton 1 The power requirements listed are for each MC2KW Power Module, two are required for each MC2KW Power Amplifier 2 Interconnect cables are supplied with the MC2KW Output Module and both MC2KW Power Modules connect to the MC2KW Output Module. 2 1. The heavy notes on the schematic denote the primary signal path. 2. Unless otherwise noted, all voltages indicated on the schematics are measured under the following conditions: a. AC input at 120 volts, 50/60Hz. b. All voltages are +/-10% with respect to ground. A high impedance (10 megaohm) voltmeter must be used. 3. Unless otherwise specified: a. Resistor values are in ohms. b. Capacitor values are microfarads (uF). c. Inductor values are in microhenries (uH). 4. On PC board drawings, Square pad indicates: a. Polarized Capacitors - Positive b. Diodes - Cathode c. Others - Pin 1 5. WARNING Parts marked with the symbol have critical characteristics. Use only replacement parts recom- mended by the manufacturer. 6. Soft startup procedure for servicing: 1. Interconnect output module and power modules 2. Connect Output Module to 120VAC 3. Connect Power Modules to variac and set the output to zero. 4. Turn Output Module power switch to on. (This will energize the power relays in the Power Modules.) 5. Gradually advance the variac to 120VAC while monitoring the AC current.
