5061 Installation notes • To identify the color coded cable bands to the connectors, see "Transfer high voltage power supply (HVPS)" on page 5-20. • When installing the transfer HVPS board, route the cable to the HVPS input connector at CN1 (C) over the cable to the yellow transfer contact (D), under the cable to the magenta transfer contact (E), and attached to the cable tie (F). This makes sure the toroid (G) does not come into contact with the motor when the card is in place. Repair information 4-93
