Operation at the full rated output should not be attempted unless this line is capable of supplying at least 15 amps of peak current. It is strongly recommended that you operate this amplifier from a 234VAC line. The amplifier may be operated from a 117VAC power source capable of supplying at least 30 Amperes. To configure the amplifier for 117VAC or 200VAC operation, remove the voltage selection jumper cover on the rear panel of the amplifier and install appropriate jumpers (see illustration below). BE SURE YOU HAVE REMOVED THE LINE CORD PLUG FROM YOUR WALL SOCKET BEFORE REMOVING THE JUMPER COVER. IF YOU FAIL TO UNPLUG YOUR AMPLIFIER, YOU WILL EXPOSE YOURSELF TO LETHAL VOLTAGES. Install an appropriate plug on the power cord to mate with your wall receptacle. If you change the operating voltage as described above, be sure to install the proper fuse. The fuse is a type SFE, 15 Amp for 234 VAC & 200 VAC operation, 30 Amp for 117 VAC operation All Commander II amplifiers manufactured for export are wired for 200 or 234VAC, 50 or 60 Hz, depending on the final destination. Location of your Commander II requires that no equipment be placed directly above it, as air expelled from the tube exhaust can become quite hot. Allow at least 3 inches clearance on either side of the unit and between other equipment. Extending the tilt bail located on the bottom of the chassis improves the cooling airflow. To switch from transmit to receive the Commander II requires a contact closure or keying circuit capable of sinking 55ma of positive voltage (12 VDC open circuit) to ground. This connection is made to the RCA jack on the rear panel marked RELAY. Read the manual that came with your transceiver to determine the proper external connections. On some transceivers, this is not provided, and an alternate circuit will be required. Always use shielded cable for these connections. Connect a good quality thruline Wattmeter between the amplifier output jack and the antenna or dummy load using RG8 or better coax.
