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!
Risk.of.explosion.if.used.in.Ex.area!
To avoid the risk of explosion, connect the Ex device to the power supply as described below:
• Secure cable connections, which use circular connectors, with suitable locking clips.
(For example: EXCLIP, FA. Phoenix Contact,
Type SAC-M12-EXCLIP-M, Art. no. 1558988 or
Type SAC-M12-EXCLIP-F, Art. no. 1558991.
• Use only cable and line entry points which have been approved for the respective application area. Screw
cable and line entry points into place according to the associated installation instructions.
• Install pre-assembled cable glands according to the installation instructions supplied by the cable gland
manufacturer.
Before start-up in the Ex area, check whether the cable gland was installed as described in these installation
instructions.
• Close all unnecessary cable glands with lock screws approved for the explosions area.
WARNING!
Risk.of.injury.from.improper.installation!
• Installation may be carried out by authorized technicians only and with the appropriate tools!
Risk.of.injury.from.unintentional.activation.of.the.system.and.an.uncontrolled.restart!
• 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 100: Pin assignment; X1 -
M12, 8-pole circular connector; PROFIBUS DP”) and
→
X2 - socket M12, 5-pole, inversely coded (see Table 101“Table 101: 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).
