3.4 VOLTAGE SELECTION
3.41 If you have a 208, 220 or 240 V ATS the voltage selection can be changed. The
factory setting is either set to HIGH (220 to 240 V) or LOW (208 V) depending on
what ATS model was ordered. If the factory preset is not desired, performing the
following steps will change the voltage transfer points.
3.42 Make sure both Primary and Backup AC sources to the ATS are de-energized.
3.43 Remove the ATS case cover.
3.44 Locate the jumper at JP1 (HIGH) or JP2 (LOW). See Figures 7 or 8.
3.45 To change the voltage selection simply move the Jumper from the JP1 (HIGH) to
JP2 (LOW) position or JP2 (LOW) to JP1 (HIGH) position (depending on the factory
preset of your ATS).
3.46
Replace ATS case cover.
