• When connecting the XCL8010 Controller Module or Excel 800 I/O modules, both VDE, National Electric Code (NEC) or equivalent, and any local regulations concerning grounding and zero voltage must be observed.
• Electrical work should be carried out by a qualified electrician.
• The electrical connections must be made at the terminal blocks. The corresponding connection diagrams are located on the individual controller module and I/O modules.
• For Europe only: To comply with CE requirements, devices with a voltage in the range of 50 ... 1000 VAC or 75 ... 1500 VDC, which are not provided with a supply cord and plug or with other means for disconnection from the supply having a contact separation of at least 3 mm in all poles, must have the means for disconnection incorporated in the fixed wiring.
Risk of electric shock or equipment damage!
► Do not touch any live parts in the cabinet.
► Disconnect the power supply before making connections to or removing connections from terminals of controller or I/O modules.
► Do not use spare terminals as wiring support points.
► Do not reconnect the power supply until you have completed the installation.
Observe precautions for handling electrostatic sensitive devices.
Wiring Push-In Terminals
The terminal sockets of the pluggable I/O modules are available in versions (XF82…) featuring convenient push-in terminals for easy wiring. Of the mixed I/O modules, the XF830A likewise features push-in terminals.The terminal sockets of the pluggable I/O modules are available in versions (XFU82…) featuring screw-type terminals. The mixed I/O modules are likewise available in a version (the XFU830A) featuring screw-type terminals.
