1. Safety Installation, Wiring or Handling
• Discharge static electricity before installation or wir-
ing in order to avoid electric equipment damage.
2. Preface
• CLICK C0-08TR-3 is supported by CLICK Programming software Ver 2.60
or higher.
3. Compliant Crimp-type terminal
• I/O terminals
4. The following crimping ferrules are recommended for 24VDC
terminal and I/O terminals of CPU and Expansion I/O.
5. Safety Standard
• To comply with safety standards, please observe and use the following:
Please use SELV (as defined by UL61010-2-201) and Limited Energy (as
defined by UL61010-1, 9.4)
Please ensure basic insulation is provided between each relay block.
In order to comply with IEC/UL 61010-2-201 if the output is connected
to a circuit lower than 30V, please provide an external isolation before
the relay output terminals. Basic isolation requires an air separation of at
least 1.5 mm, a creepage distance of at least 2.5 mm, and a withstand
voltage of 1500V rms.
Enclosures
It is important to select the appropriate enclosure to ensure safe and proper oper-
ation of your CLICK PLC system. Control applications vary and yours may require
additional considerations. At a minimum your enclosure should include:
• Conformance to electrical standards
• Protection from the elements in an industrial environment
• Common ground reference
• Maintenance of specified ambient temperature
• Access to equipment
• Security or restricted access
• Sufficient space for proper installation and maintenance of equipment
CAUTION
• When installing modules and CPU on DIN rails, always
use end brackets on both ends of assembly.
• You should use 35mm width DIN Rails.
• You should use M4 size screws when you surface mount.
• You should tighten the screws with a spring washer and
a small round washer and torque (0.5 to 0.6 N·m).
CAUTION
Do not operate without first installing safety cover over power supply
leads.
