The Compax3H High voltage (H055V4, H095V4, H125V4, H155V4
C3H has a flip-down door on its front panel to connect into (rj11 connector) with the SSK32/20 supplied with the C3H's.
Only 24volts control power needs to be on for communication with the drive; AC motor voltage does not need to be on and is separate from the control power.
Note: This only works if there the jumper installed!
If the SSK32/20 dongle has been lost or misplaced, users can connect via the x10 but it's up underneath where the AC power and motor cables come into the C3H.
For safety reasons, power down the AC power before connecting the serial cable into x10.
Other than that, it's same as a Compax3S: C3 Servomanager Communication Troubleshooting
