Mounting and wiring Installation on mounting rails WARNING Risk of electric shock and damage of device! Bring the bus terminal system into a safe, powered down state before starting installation, disassembly or wiring of the bus terminals! Assembly Fig. 8: Attaching on mounting rail The bus coupler and bus terminals are attached to commercially available 35 mm mounting rails (DIN rails according to EN 60715) by applying slight pressure: 1.
Mounting and wiring Disassembly Fig. 9: Disassembling of terminal Each terminal is secured by a lock on the mounting rail, which must be released for disassembly: 1. Pull the terminal by its orange-colored lugs approximately 1 cm away from the mounting rail. In doing so for this terminal the mounting rail lock is released automatically and you can pull the terminal out of the bus terminal block easily without excessive force.
Mounting and wiring Fig. 10: Power contact on left side NOTE Possible damage of the device Note that, for reasons of electromagnetic compatibility, the PE contacts are capacitatively coupled to the mounting rail. This may lead to incorrect results during insulation testing or to damage on the terminal (e.g. disruptive discharge to the PE line during insulation testing of a consumer with a nominal voltage of 230 V).
Mounting and wiring Installation instructions for enhanced mechanical load capacity WARNING Risk of injury through electric shock and damage to the device! Bring the Bus Terminal system into a safe, de-energized state before starting mounting, disassembly or wiring of the Bus Terminals! Additional checks The terminals have undergone the following additional tests: Verification Explanation...

80°C at the wire branching points, then cables must be selected whose tempera- ture data correspond to the actual measured temperature values! • Observe the permissible ambient temperature range of 0 to 55°C for the use of Beckhoff fieldbus compo- nents standard temperature range in potentially explosive areas! •...
IECEx Pay also attention to the continuative documentation Ex. Protection for Terminal Systems Notes on the use of the Beckhoff terminal systems in hazardous areas according to ATEX and IECEx that is available for download on the Beckhoff homepage www.beckhoff.com!
The general use of hardware and software from the open PC world requires some checking: Unsuitable components can upset the PC system. Beckhoff integrates a handy display of the real-time jitter in order to provide administrators with a simple means of evaluating hardware and software. A system message during operation can draw attention to error states.

According to the requirement for operating resources, the TwinCAT software devices can be distributed: TwinCAT PLC programs can be executed on PCs and on Beckhoff Bus Terminal controllers. A "message router" manages and distributes all the messages, both in the system and via TCP/IP connections. PC systems can be connected to one another by TCP/IP;...
