Installation and Commissioning

Installation and CommissioningConnecting Signals3.5 ConnectionsDetailed information about connection locations and functions will be found in chapter11, Circuit Diagram.3.5.1 To screw terminalPanel unit and I/O units are provided wiyh keyed screw terminals for cables with anarea between 0.25 and 1.5 mm 2 . A maximum of two cables may be used in any oneconnection. The cable screen must be connected to the cabinet wall using EMC. Itshould be noted that the screen must continue right up to the screw terminal.The installation should comply with the IP54 (NEMA 12) protective standard.Bend unused conductors backwards and attach them to the cable using a clasp, forexample. In order to prevent interference, ensure that such conductors are not connectedat the other end of the cable (antenna effect). In environments with much interference,disconnected conductors should be grounded (0 V) at both ends.3.5.2 To connectors (option)Industrial connectors with 4x16 pins for contact crimping (complies with DIN 43652)can be found on the left-hand side or front of the cabinet (depending on the customerorder) See Figure 26 and Figure 17.In each industrial connector there is space for four rows of 16 conductors with a maximumconductor area of 1.5 mm 2 . The pull-relief clamp must be used when connectingthe shield to the case.The manipulator arm is equipped with round Burndy/Framatome connectors (customerconnector not included).Bend unused conductors backwards and attach them to the cable using a clasp, forexample. In order to prevent interference, ensure that such conductors are not connectedat the other end of the cable (antenna effect). In environments with much interference,disconnected conductors should be grounded (0 V) at both ends.When contact crimping industrial connectors, the following applies:Using special tongs, press a pin or socket on to each non-insulated conductor.The pin can then be snapped into the actual contact.Push the pin into the connector until it locks.Also, see instructions from contact supplier.A special extractor tool must be used to remove pins from industrial connectors.When two conductors must be connected to the same pin, both of them are pressed intothe same pin. A maximum of two conductors may be pressed into any one pin.Product Manual IRB 1400 33
