Note
Operative malfunction due to impermissible cabling.
• To connect the I-port devices to the CTEL master
module, use only the special I-port connecting cables
from Festo.
• Please note that the length of the I-port connecting
cables is limited to a maximum of 20 m.
You will then avoid errors in data exchange between the
CTEL master module and the connected devices.
To ensure protection class IP65/IP67, the unused I-port
interfaces must be sealed with cover caps. These must be
ordered separately (type ISK-M12).
