Recommended Ferrules and Tools
Recommended ferrules
Note: 1. Make sure that the outer diameter of the wire coating is 
smaller than the inner diameter of the insulation sleeve of 
the recommended ferrule.
2. Make sure that the ferrule processing dimensions conform 
to the following figures.
Recommended Flat-blade Screwdriver
Use a flat-blade screwdriver to connect and remove wires.
Use the flat-blade screwdriver.
The following table shows manufacturers and models as of 2015/Dec.
• Refer to the contents of this datasheet for cable selection and other 
conditions for compliance with EMC standards.
Precaution on EN Standard Compliance
The K8DT complies with EN 60947-5-1 when it is built into a panel, 
but observe the following handling methods to ensure compliance 
with the requirements of this standard.
Wiring
Overvoltage category III
Pollution degree 2
• Open-frame Device
• If basic, double, or reinforced insulation is required, use the basic, 
double, or reinforced insulation defined in IEC 60664 that is 
suitable for the maximum applied voltage for the clearance, solid 
insulation, and other factors.
• There is basic insulation between the power supply terminals and 
input terminals.
• There is basic insulation between the power supply terminals and 
output terminals.
• There is basic insulation between the input terminals and output 
terminals.
• Operating section must have reinforced or double insulation.
• The sides of the case are not isolated.
• Connect the output contacts (contacts with different polarity) so 
that they reach the same potential.
