Output Wiring; Common Precautions For Input And Output Wiring - Panasonic AFPE224300 User Manual

3.4.2 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 type, be sure to connect a diode across the ends
of the load.
Precautions when using capacitive load
When connecting large rush current loads, install a protection circuit (below) to minimize their effect.
Provide over-load protection with an external fuse
There is no fuse protection built into the output circuit. Therefore, in order to protect against overheating of
the output circuit by possible short circuit, install an external fuse at each point. However, in cases such as
short circuits, the control unit itself may not be able to be protected.

3.4.3 Common precautions for input and output wiring

Separate the input, output, and power wiring
- 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 wiring are separated from
the power wiring, as much as possible. Do not route them through the same duct or bind them together.
- Separate the input or output wire from the power's high voltage wire by at least 100 mm /3.937 in.
