The following diagram shows how to wire the power supply.
24 V DC
(12 V DC)
1. Do not perform a voltage withstand test on the DC power supply terminals.
The test might damage the PLC's internal components.
2. When equipment must conform to the EC Directives (Low-voltage Direc-
tives), use a power supply with double insulation or reinforced insulation.
The following tables provide output terminal block specifications.
