WIRING AND SET-UP
General Safety Considerations
All wiring must comply with applicable electrical codes and
ordinances, including VDE, National Electric Code (NEC)
or equivalent, and any local regulations must be observed.
Refer to job or manufacturer’s drawings for details. Local
wiring guidelines (e.g., IEC 364-6-61 or VDE 0100) may
take precedence over recommendations provided here.
Electrical work should be carried out by a qualified
electrician.
Electrical connections must be made at terminal blocks.
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!
►
Observe precautions for handling electrostatic sensitive
devices.
►
Do not touch any live parts in the cabinet.
►
Do not open the device housing.
►
Disconnect the power supply before making connections to
or removing connections from terminals of the CLIF-
CBUSLC and devices wired to it.
►
Do not use spare terminals as wiring support points.
►
To prevent risk of injury due to electrical shock and/or
damage to the device due to short-circuiting, low-voltage
and high-voltage lines must be kept separate from one
another.
►
All terminals are protected (up to 24 Vac) against short-
circuiting and incorrect wiring. Higher voltages may
damage the device.
►
Do not reconnect the power supply until you have
completed the installation.
Fusing Specifications
System Fusing
We recommend that the system be equipped with an external
fuse.
Fusing of Active Field Devices
F2 (depends upon given load).
Wiring Terminals
The CLIF-CBUSLC is equipped with push-in terminal plugs.
Fig. 14. Inserting/removing wires from push-in terminals
NOTE:
With solid conductors, ferrules are prohibited.
NOTE:
Use only one conductor per push-in terminal.
NOTE:
If, nevertheless, two stranded wires are to be
connected to a single push-in terminal, twin wire
end ferrules must be used.

Power Supply
Powering CLIF-CBUSLC
Power is supplied via a removable terminal plug (attached to
terminals 1 and 2).
The power supply of the CLIF-CBUSLC must conform to
Safety Class II. To reduce overall current consumption, the
CLIF-CBUSLC can be powered by a switch power supply
(rather than by a transformer). See also Table 3 on pg. 3.
NOTE:
Danger of short-circuiting when another controller
besides the CLIF-CBUSLC is supplied by the same
transformer if proper polarity is not ensured. See
Fig. 15.
