Mounting/Installation Instructions

Shielding and routing bus cables
Only use shielded cables and connection elements that also meet the requirements of
category 5, class 2 in compliance with IEC 11801 edition 2.0.
Correct shielding of the bus cable attenuates electrical interference that may occur in
industrial environments. The following measures ensure the best possible shielding:
• Manually tighten the mounting screws on the connectors, modules, and equipotential
bonding conductors.
• Use only connectors with a metal housing or a metallized housing.
• Connect the shielding in the connector over a wide surface area.
• Apply the shielding of the bus line on both ends.
• Route signal and bus cables in separate cable ducts. Do not route them parallel to
power cables (motor leads).
• Use metallic, grounded cable racks in industrial environments.
• Route the signal cable and the corresponding equipotential bonding close to each
other using the shortest possible route.
• Avoid using plug connectors to extend bus cables.
• Route the bus cables closely along existing grounding surfaces.

Setting the DIP switches 2
0
and 2
1
DIP switch 2
0
If the "2
0
" switch is set to "1" (= ON), the following default IP address parameters are set
when activating the DC 24 V backup voltage:
• IP address: 192.168.10.4
• Subnetwork mask: 255.255.255.0
• Default gateway: 1.0.0.0 for EtherNet/IP (192.168.10.4 for PROFINET)
• P785 DHCP / Startup Configuration: Saved IP parameters (DHCP is deactivated)
DIP switch 2
1
DIP switch "2
1
" is used to set the fieldbus protocol that is currently used.
• 2
1
= "1" (= ON) the EtherNet/IP / Modbus TCP/IP fieldbus protocol is active
• 2
1
= "0" (= OFF) the PROFINET fieldbus protocol is active.
STOP!
In case of fluctuations in the ground potential, a compensating current may flow via the
bilaterally connected shield that is also connected to the protective earth (PE). Make
sure you supply adequate equipotential bonding in accordance with relevant VDE
regulations in such a case.
NOTE
The setting of the "2
0
" DIP switch is only adopted with a power-on reset (switching on
and off line voltage and DC 24 V backup voltage).
