Precautions For Correct Use - Omron K3GN Series Instructions Manual

Precautions for Safe Use
1. Use and store within the proper temperature and humidity
described in the specifications.
2. Provide sufficient space around the product for heat dissipation.
3. When using the product stored unused over a year after
purchasing, the product features may not be utilized sufficiently.
4. Avoid storing outdoors or in a place that receives direct sunlight
(including during transportation).
5. The service life of the output relays depends on the switching
capacity and switching conditions. Consider the actual application
conditions and use the product within the rated load and electrical
service life. Using the product beyond its service life may result in
contact welding or burning.
6. Be sure to confirm the name and polarity for each terminal before
wiring the terminal block and connectors. Faulty wiring may cause
destruction or burnout of internal parts.
7. Use the product within the noted supply voltage and rated load.
8. Do not connect anything to unused terminals.
9. Output turns OFF when the mode is changed or settings are
initialized. Take this into consideration when setting up the control
system.
10.Install an external switch or circuit breaker and label them clearly
so that the operator can quickly turn OFF the power.
11.Ensure that the rated voltage is achieved no longer than 2 s after
turning the power ON. When applying a voltage gradually, the
power supply may not reset or the output may function in an
uncertain manner.
12.Mount to a panel between 1 and 5 mm thick.
13.Use the specified size of crimp terminals (M3, width: 5.8 mm
max.) for wiring. To connect bare wires, use AWG 28 to AWG 16
to wire the power supply terminals and AWG 22 to AWG 14 for
other terminals. (Length of exposed wire: 6 to 8 mm)
14.Allow the product to operate without load for at least 15 minutes
after the power is turned ON.

Precautions for Correct Use

1. Note that errors may be increased by the magnification of the
scaling function.
2. When using a noise filter on the power supply, check that the filter
is suitable for the supply voltage and current ratings, and then
attach the noise filter as close as possible to the K3GN.

Shielded cable
Connect in the direction that best
reduces noise.
3. Avoid using the K3GN in places near a radio, television, or other
wireless device. These devices can cause radio disturbances
which will adversely affect the K3GN.
