Conservative designs - CSA certified (209651). NOTE: A productionrunning chang has been made to the primary winding - effective with August 2009 production. Choice 1 (115 VAC Input): For those customers who need the 115V input - nothing has changed - simply use the White & Gray wires and tape the Black wire (see above schematic). Note: Gray wire is actually BROWN on only our Part Number 278CX. Choice 2 (125 VAC Input): For those customers who are seeing too high a secondary voltage due to higher primary line voltages (roughly 125V input) - use the White & Black wire and tape the gray wire (see schematic). NOTE: Most of the mounts do not apply to choices 1 and 2 above. See their respective drawings for available primary voltages.
