DANGER!
Risk of injury due to electrical shock.
▶ Before reaching into the device or the equipment, switch off the operating voltage and secure to prevent
reactivation.
▶ Observe applicable accident prevention and safety regulations for electrical equipment.

▶ Secure system from unintentional activation.
▶ Following installation, ensure a controlled restart.
For operation of the device the following must always be connected:
→ X1 - circular connector M12, 8-pole (for operating voltage see Table 100“Table 102: Pin assignment; X1 -
M12, 8-pole circular connector; PROFIBUS DP”) and
→ X2 - socket M12, 5-pole, inversely coded (see Table 101“Table 103: Pin assignment; X2/X3 - M12, 5-pole
circular connector/socket - bus connection, PROFIBUS DP”).
NOTE!
Electromagnetic compatibility (EMC) is only ensured if the appliance is connected correctly to an
earthing point.
On the outside of the housing is a TE terminal for connection of the technical earth (TE).
• Connect the TE terminal to the earthing point via a shortest possible cable (maximum length 30 cm).
