1. Notes on this operating manual This manual is a key aid when it comes to ensuring proper operation of the device. It contains important information and safety notes to help you use the devices correctly, economically and in the intended manner. The manual helps to avoid dangers, to reduce repair costs and downtimes, and to increase the reliability and operating life of the devices. During installation, all the manuals for system modules and components must be taken into account. 2. Safety instructions for operation 2.1 Intended use Only the permitted signals and signal strengths may be applied to the connections of the data loggers and modules used here. Installation is only permitted indoors. For installation outdoors or in a dusty environment, the device must be installed in a standardized protective enclosure. 2.2 Personnel Installation, commissioning and maintenance of the device may only be performed by a qualified electrician. Given their specialist training, knowledge, experience and familiarity with the relevant standards and regulations, a qualified electrician is in a position not only to carry out work on electrical systems but also to recognize and avoid possible dangers unaided. The qualified electrician must comply with the occupational health and safety laws in force. Please note in particular: all national installation and set-up regulations (e.g. VDE in Germany), all generally accepted codes of practice, information on transport, installation, operation, service, maintenance and disposal given in the documentation for the devices used, specific values, limits and information relating to operating and ambient conditions on type plates and in data sheets. 2 48

Overview of interfaces Overview of interfaces (1) Analog inputs (DI1 DI4) (7) Ethernet (2) Reset button (8) RS485 (3) Digital inputs (DI1 DI4) (9) RS232/422 (4) Power supply (10) Digital output (DO1) (110 V 230 V AC) (5) RJ45 phone socket (PSTN) (11) Switch between RS232 / RS422 (6) Power supply (24 V DC) Can also be operated as RS485 for additional Modbus devices 3 48
4. Cabling 4.1 RS485 and RS232/422 The two RS485 and RS232/422 interfaces are used to query information recorded on various bus devices such as inverters, power quality analyzers, etc. The RS232/422 interface can also be used as an RS485 interface. In order to do this the interface has to be operated in RS422 mode (for this, please refer to the manual of your WEB log data logger). Which interface you should use to connect inverters and accessories depends on your specific driver. Please refer to the appropriate driver datasheet (http://www.meteocontrol.de/downloads/). Please note the following regarding the bus cabling: All devices on a bus must use the same protocol to communicate. The data logger functions exclusively as a master on the bus. The maximum permitted number of bus devices has to be observed (see driver datasheets). The order of the bus devices on the bus is unimportant. The use of a repeater is necessary for every 32nd bus device and for long cable runs. The bus should be cabled with a twisted and shielded pair of wires. The shield of the bus cable must be grounded at one end of the connection only. The data logger does not have its own grounding When you wire the bus wires, make sure that AC and DC cables are routed separately. Do not switch the buses signal wires. Different manufacturers interpret the RS485 interface s underlying standard differently. A and B wire labels may be different for different manufacturers. The + and indicators, on the other hand, are unambiguous. To prevent reflections, the bus must always be terminated with a parallel terminator. 4 48
Daisy chain If you want to connect more than one device to the bus, you must daisychain the connection. This means that different devices can only be queried jointly if they use the same communication protocol and the same serial communication parameters (baud rate, data bits, parity, stop bits). The first and last device on the bus must be terminated with a resistor. The data logger is provided with integrated terminating resistors that are permanently activated. Daisy chain cabling RS485/422 5 48
Star wiring Another possible way of operating multiple devices on the RS485 bus is called star wiring. In this wiring variant, a HUB 6 Port RS485 S (item number 421.641) is used to seperate the bus into a serveral bus strings. To connect the HUB 6 Port RS485 S to the WEB log, please use a Connect Universal RS cable (item number: 422.537). Various devices can only be queried together if they communicate with the same protocol and have identical serial communication parameters (baud rate, number of data bits, parity, stop bits). Each bus string can have a maximum length of 1200 m. All the devices on the same bus string are wired together in a daisy chain. The first and last device of each bus string must be terminated with a resistor. The HUB has integrated terminating resistors at each interface, which are permanently activated. In this wiring variant, the total number of bus devices may not exceed the maximum permissible number of bus devices. Star wiring for RS485 6 48
