P1) Mounting
Solid wire
The EB3C-N relay barrier can be installed
in any direction.
6~8mm
Install the EB3C-N relay barrier securely
to withstand vibrations.
Stranded wire（ferrule）
When mounting the EB3C-N relay barrier
onto a DIN rail, make sure to press in theclamp completely. Use the BNl6
6~8mm
mounting clips to prevent the EB3C-N
relay barrier from moving sideways.
< Applicable Crimping Terminal >2) Terminal Wiring
φ3.2min.
Provide IP20 for wiring of the EB3C-N
relay barrier. Use shielded wires for barecrimping terminals.
Using a ø5.5 mm or smaller screw driver,3max.
5.4min.
tighten the screw to a torque of 0.6 to(AllDimensionsin mm)
1.0Nm .
3) Output
When required, provide a short-circuit protection externally.
Do not apply an expressively high voltage (clamps at 33V, 1W) or reverse
voltage, otherwise the transistor output may be damaged.
4) PowerDo not apply an expressive power, otherwise the EB3C-N relay barrier may bedamaged.
AC power type may operate at a low voltage (20V AC).
5) Signal Input
Use switches which can open/close the input voltage and current.
6) Extraneous Noise (EMC)
Induction of excessive noise may cause malfunction and damage to the EB3C-N
relay barrier.
When the protection circuit (thyristor) inside the DC-DC converter operates,remove noise and restart the EB3C-N relay barrier. Operation may be restored.
