Description The NG4 power supply supplies regulated direct voltages for supplying power to the respective devices of the product family of I/O components. The device supplies regulated direct voltage 24 V DC at a power of 16 watts. A parallel operation of several power supply units is not allowed. The secondary voltage can only be tapped at the right side of the plug connector and at the screw-type terminals on the top of the module. The bus communication is looped through on both sides of the plug connectors. 8038/899243-01 Power Supply NG4 110561-01 3.

In case of questions that cannot be answered with these in- structions please consult supplier or manufacturer. The indicated installation directions or rules are applicable to the Federal Republic of Germany. If the device is used in other countries it applies to the equipment installer or the user to meet the national directions. Safety Instructions Keep the applicable directions for industrial safety and prevention of accidents as well as the VDE rules. Technicians and/or installers are informed that they have to electrically discharge themselves as prescribed before installation or maintenance of the devices. Only qualified personnel shall do mounting and installation work with the devices, see section “qualified personnel”. The information of these instructions have to be read and understood by every person using this device. Symbols Warning of dangerous electrical voltage Danger means that non-observance may cause risk of life, grievous bodily harm or heavy material damage. Qualified Personnel Qualified personnel in the sense of these instructions are persons who are well versed in the use and installation of such devices and whose professional qualification meets the requirements of their work. This includes for example: •Qualification to connect the device according to the VDE specifications and the local regulations and a qualification to put this device into operation, to power it down or to activate it by respecting the internal directions. •Knowledge of safety rules. • Knowledge about application and use of the device within the equipment system etc. METZ CONNECT GmbH Im Tal 2 | 78176 Blumberg | Germany | Phone +49 7702 533-0 | Fax +49 7702 533-433 Mounting instruction see www.metz-connect.com • The module can be aligned without interspace. Use the jumper plug to connect bus and supply voltage when the modules are mounted in series. • The maximum quantity of modules connected in line is limited to 15 or to a maximum power consumption of 2 Amps (AC or DC) per connection to the power supply. For any similar block of additional modules a separate connection to the power supply is mandatory. Preparing cable for connection. Strip the wire by 7 mm, attach an end sleeveif necessary, insert the wire into the contact and tighten the terminal screw with a screwdriver. 2 3 4 7 mm 1 6. Mounting Power down the equipment Mount the module on standard rail (TH35 per IEC 60715 in junction boxes and/or on distribution panels). Installation Electric installation and device termination shall be done by qualified persons only, by respecting all applicable specifications and regulations. +24V NG4 B+ A- B+ A- 24 V GND L 24V 24V 24V TTT L N N A- B+ 24V24V24V24V24V24V24V24V24V24V B+B+B+B+B+ A-A-A-A- B+B+B+B+B+ A-A-A-A- 24 V24 V24 V24 V GNDGNDGNDGNDGND 24 V24 V24 V24 V GNDGNDGNDGNDGND 2+ 2+ 2+ 2+ 2+ 2- 2- 2- 2- 2- 1+ 1+ 1+ 1+ 1+ 1- 1- 1- 1- 1- 3+ 3+ 3+ 3+ 3+ 3- 3- 3- 3- 3- 4+ 4+ 4+ 4+ 4+ 4- 4- 4- 4- 4- B A- B A- 24 V 24 V B+B+ GNDGND No 24 V DC transmission!
