Precautions for Correct Use
• The line length from the safety output terminals to the output devices (L1, L2, L3, and L4) is
100 m max. for each line.
• The total length of cable that is connected to one test output must be as described in
4-3-1 Safety Input Function
on page 4 - 10.

Connecting More Than One Output Device
The IOG terminals on the Safety Output Unit are connected internally in the Unit. Make sure that
the current that flows through each IOG terminal is less than the current capacity of the I/O power
supply terminals.
If the wiring is shared for the IOG lines to the output devices, the sum of the output currents will
flow in the IOG line. Therefore, wire the IOG lines separately.
