Ventilation
If the air inlet or air outlet has a filter, clean the filter regularly to
prevent it from clogging and ensure an efficient flow of air.
Do not locate any objects around the air inlet or air outlet, otherwise
the objects may obstruct the proper ventilation of the control panel.
Do not surround the SSR
with ducts, otherwise the
heat radiation of the SSR
will be adversely affected.

A heat exchanger, if used, should be located in front of the SSR Units
to ensure the efficiency of the heat exchanger.
Please reduce the ambient temperature of SSRs.
The rated load current of an SSR is measured at an ambient
temperature of 25 or 40 °C.
An SSR uses a semiconductor in the output element. This causes
the temperature inside the control panel to increase due to heating
resulting from the passage of electrical current through the load. To
restrict heating, attach a fan to the ventilation outlet or air inlet of the
control panel to ventilate the panel. This will reduce the ambient
temperature of the SSRs and thus increase reliability. (Generally,
each 10°C reduction in temperature will double the expected life.)
Example: For 10 SSRs with load currents of 20 A,
If there are other instruments that generate heat in the control
panel other than SSRs, additional ventilation will be required.
