Verify IP settings via the front panel; ping the device; ensure ports 23 (Telnet) or 502 (Modbus) are open. Wrong CTR or PTR settings applied. sel 735 manual
Ensure the panel cutout matches the specific chassis style (e.g., standard 19-inch rack mount or drawout switchboard case).
Shorting blocks must be installed on the CT secondary circuits. Never open-circuit a live CT as it generates lethal voltages.
