Serviceable Parts
The drive contains few serviceable parts. The following parts are considered replacement parts on the drive:
• Main control board and I/O Terminal board I/O PCBs.
• Cooling fan(s)
• Front cover
Replace the drive if the main power circuitry is damaged. Contact your local OYMC representative before replacing parts
if the drive is still under warranty. OYMC reserves the right to replace or repair the drive according to OYMC warranty
policy.
WARNING! Electrical Shock Hazard. Do not connect or disconnect wiring while the power is on. Failure to comply can result in serious
personal injury. Before servicing the drive, disconnect all power to the equipment. The internal capacitor remains charged even after
the power supply is turned off. The charge indicator LED will extinguish when the DC bus voltage is below 50 Vdc. To prevent electric
shock, wait at least five minutes after all indicators are OFF and measure the DC bus voltage level to confirm safe level.

Terminal Board Overview
The drive has a modular I/O terminal block that facilitates quick drive replacement. The terminal board contains on-board
memory that stores all drive parameter settings and allows the parameters to be saved and transferred to the replacement
drive by disconnecting the terminal board from the damaged drive then reconnecting the terminal board to the replacement
drive. There is no need to manually reprogram the replacement drive.
