Installation / Setup
After unpacking the Model HA-6 Transverter, inspect it for any damage that may have occurred during transit and file a claim with the carrier if necessary. Avoid placing the unit near heat sources and ensure there is at least three inches of clearance on each side for proper air circulation. The transverter should be connected to a Model P-26 or equivalent power supply, which requires a 105-volt to 125-volt, 60-cycle AC power source. When installing, interconnect the power supply and transverter using the high voltage and multi-conductor cables, and insert the jumper plug into the unused 11-pin POWER socket of the power supply.
