1. The heavy notes on the schematic denote the primarysignal path.
2. Unless otherwise noted, all voltages indicated on theschematics 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 - Positiveb. Diodes - Cathodec. Others - Pin 1
5. WARNINGParts marked with the symbol have criticalcharacteristics. Use only replacement parts recom-mended by the manufacturer.
6. Soft startup procedure for servicing:1. Interconnect output module and power modules2. Connect Output Module to 120VAC3. 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.
