◆
Prior to Installing the Option Unit
Prior to installing the PROFIBUS-DP Option, wire the drive and make necessary
connections to the drive terminals. Refer to the HF-520 manual for information on wiring
and connecting the drive. Verify that the drive operates normally without the option
installed.
◆
Installing the Option Unit
Remove the front cover of the drive before installing the PROFIBUS-DP Option. Follow the
directions below for proper installation.
1.
Switch off the power supply to the drive.
DANGER! Electrical Shock Hazard - Do not connect or disconnect wiring while the power is on. Failure to
comply will result in death or serious injury. Before installing the PROFIBUS-DP Option, disconnect all
power to the drive. 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.
2.
Remove the front cover. The original drive front cover may be discarded because it
will be replaced by the PROFIBUS-DP Option cover in step 7.
