If the current lampholders <br />are shunted, remove them and <br />replace them with non-shunted <br />lampholders. Make new con- <br />nections directly to terminals as <br />indicated above. <br />Keystone can provide any style <br />replacement lampholders. <br />Call us at 800-464-2680. <br />SINGLE-ENDED WIRING DIAGRAM <br />Figure A Typical Ballast Configurations: <br />PROGAM START <br />LINE <br />NEUTRAL <br />YELLOW <br />YELLOW RED <br />RED <br />BLUE <br />BLUE <br />LAMP <br />LAMP <br />BALLAST <br />PREHEAT WITH STARTER <br />LINE BLACK <br />BALLAST <br />LAMP <br />S <br />INSTANT START <br />LINE <br />NEUTRAL <br />BLUE <br />BLUE <br />RED <br />LAMP <br />LAMP <br />BALLAST <br />2.
