The units can be set to operate from an input voltage of 230 VAC, 60 Hz. by changing the position of an internal jumper. The procedure for conversion to input voltage of 230 VAC, 50 Hz. is as follows: . Switch off the unit and unplug the power cord from the AC outlet . Remove the top cover . For 120 VAC operation (pre-set condition), points "D" and "E" on the printed circuit board (PCB) have been connected (shorted) with a flexible wire jumper. To convert to 230 VAC input, disconnect the quick disconnect connector at point "D" by pulling it upwards. Tape this end with an insulation tape and use a cable tie to tie it securely to the wire harness running above . The fuse on the AC side for the preset input voltage of 120 VAC is rated at 250 V, 8 A. For 230 VAC operation, the fuse has to be rated at 250 V, 4A. Replace the existing 8 A fuse with a 4 A fuse. See under "SPECIFICATIONS" on page 11 for details on the 4 A fuse. .The detachable power cord that is provided has an "IEC 320-13" female connector on one end that will mate with the "IEC 320-C14" male AC inlet connector on the power supply. The other end of this power cord has a 120 VAC NEMA5-15P plug meant for connection to the 120 VAC, NEMA5-15R outlet. For operation on 230 VAC, 50 Hz, a different detachable power cord will have to be used. Use an appropriate power cord that has an "IEC 320-13" female connector on one end (for connection to the "IEC 320-C14" AC inlet connector on the power supply) and a 230 VAC plug on the other end corresponding to the 230 VAC outlet. Please ensure that the new 230 VAC power cord uses two pole, 3 wire grounding configuration (this will ensure proper earth grounding). ~~~~~~~~~~~~~~~~~~~~~~~ On 9/9/2011 9:42 AM, Jorge Diez - CX6VM wrote: > SEC 1235M ______________________________________________________________ Elecraft mailing list Home: http://mailman.qth.net/mailman/listinfo/elecraft Help: http://mailman.qth.net/mmfaq.htm Post: mailto:[email protected] This list hosted by: http://www.qsl.net Please help support this email list: http://www.qsl.net/donate.html
