Wiring and Setting Up the System
General Safety Considerations
When connecting the CLLIONLC01 or LION 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.
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.
►
Unused terminals must be closed (by completely
screwing in the terminal screws), thus preventing the
accidental touching of “live” parts.
►
Observe precautions for handling electrostatic sensitive
devices.
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. The
CLIOP830A 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
Table 22 Push-in terminals wiring specifications
NOTE:
In the case of solid conductors, the use of
ferrules is prohibited.
NOTE:
Use only one conductor per push-in terminal.
NOTE:
If two stranded wires are to be connected to a
single push-in terminal, twin wire end ferrules
must be used.
Wiring Screw-Type Terminals
The terminal sockets of the pluggable I/O modules are also
available with screw-type terminals (XSU821-22, XSU823,
and XSU824-25).
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
11.0 +1.0 mm
