Introducing a safety system for low risk machines
Designing a category 2 system has been difcult and only a redundant system (category 3) could be used
to protect machines against relatively minor hazards.
However, with the HR5S safety relay module, designing a category 2 system is easy and enables cost
reduction and saves maintenance time.

Wiring Procedure
Insert
(1) Insert the solid wire or stranded
wire with ferrule into the terminal
entrance.
(2) After wiring, tug lightly to make sure
that the wire is properly connected.
* When inserting stranded wires
directly, make sure that the pusher
in pressed down and there are no
loose wires.
Remove
(1) Press the pusher using a flat
screwdriver.
(2) Remove the wire by pressing the
pusher.
Safety Precautions
• For details on wire cross sections, striping lengths, and tightening
