5.3.2 Output Wiring
Protective circuit for inductive loads
-
With an inductive load, a protective circuit should be installed in parallel with the load.
-
When switching DC inductive loads with relay output, be sure to connect a diode across the ends of the
load.
When using an AC inductive load (Relay output type)
When using an DC inductive load
Precautions when using capacitive loads
When connecting loads with large in-rush currents, to minimize their effect, connect a protection circuit
as shown below.
Use an external fuse as overload protection
A fuse is not built in the output circuit. It is recommended to install external fuses on every circuit, in
order to prevent the output circuit to be burned out when the output is shorted. However, in some cases
such as shortcircuit, the element of the unit may not be protected.
5.3.3 Precautions Regarding Input and Output Wirings
Separate the input, output, and power lines
-
Be sure to select the thickness (dia.) of the input and output wires while taking into consideration the
required current capacity.
-
Arrange the wiring so that the input and output wiring are separated, and these wirings are separated
from the power wiring, as much as possible. Do not route them through the same duct or wrap them
up together.
-
Separate the input/output wires from the power and high voltage wires by at least 100 mm.
