Wiring and Setting Up the System
General Safety Considerations
When connecting the XCL8010 Controller Module or
Excel 800 I/O modules, both VDE, National Electric Code
(NEC) or equivalent, and any local regulations con-
cerning 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.
WARNING
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 Terminals
Wiring Push-In Terminals
The terminal sockets of the pluggable I/O modules are
available in versions (XS821-22, XS823, and XS824-25)
featuring convenient push-in terminals for easy wiring. Of
the mixed I/O modules, the XF830A likewise features push-
in terminals.
For correct wiring, cables must fulfill the following
specifications according to IEC664-1 / VDE 0110 (4.97):
Max. plug gauge
0.14 … 1.50 mm
2
Solid conductor H05/07) V-U
0.25 … 1.50 mm
2
Stranded conductor H05(07) V-K
0.25 … 1.50 mm
2
Stranded conductor with wire end
ferrules (without plastic collar)
0.25 ... 1.50 mm
2
Stripping length
8.0 +1.0 mm

Wiring Screw-Type Terminals
The terminal sockets of the pluggable I/O modules are
available in versions (XSU821-22, XSU823, and XSU824-
25) featuring screw-type terminals. The mixed I/O modules
are likewise available in a version (the XFU830A) featuring
screw-type terminals.
For correct wiring, cables must fulfill the following
specifications according to IEC664-1 / VDE 0110 (4.97):
