Common AccessoriesCommon Precautions
Method of operation of the latching lever (test
switch)
Keep the protective cover open when using the latching lever. Move
until the latching lever clicks to the ON position (ON state). After use
latching lever, in order to prevent malfunction, return the switch to
contact normal position (OFF state), and make sure the protective
cover is firmly closed.
Using the latching lever
Example: check the operation of the relay and the sequence circuit
<G3RV>
• Since the G3RV uses electronic components, do not allow it to fall,
vibrate, or apply shock that exceeds the criteria. Doing so may
result in failure, malfunction, or deterioration of performance.
• Tighten screw terminal for G3RV at torque 0.4 N · m. It may cause
short-circuit failure or burning.
• Please use the voltage and current suitable for the input and output
terminal portion of G3RV. It may cause short-circuit failure or
burning.
Mounting
<The SSR Mounting Pitch (Panel Mounting)>
* When five or more are installed, install with 10 mm space between
each.
<Relationship of SSR and duct (duct depth)>
<Ventilation Outside the Control Panel>
• If the air inlet or air outlet has a filter, clean the filter regularly to
prevent it from clogging to ensure an efficient flow of air.
• Do not place objects that may obstruct the proper ventilation for
outside or inside the inlet or exhaust port, and in the outside
vicinity.
• A heat exchanger, if used, should be located in front of the G3RV
to ensure the efficiency of the heat exchanger.
• Please observe the ambient temperature of G3RV. The rated
current of the G3RV is measured at an ambient temperature of
25°C.
• The G3RV uses a semiconductor in the output element.
This causes the temperature inside the control panel to increase
due to heating resulting from the flow of electrical current through
the load. The G3RV reliability can be increased by adding a
ventilation fan to the control panel to dispel this heat, thus lowering
the ambient temperature of the G3RV.

(It suggests that life expectancy is doubled by each 10°C reduction
in ambient temperature.)
EMI
The G3RV is a Class A product (for industrial environments).
When used in a residential environment, it may cause radio
interference. In such case, the user may be required to take
appropriate measures.

Do not enclose the SSR in a
duct of the same height.
It will interfere with the heat
dissipation of SSR.
Use ducts that have a
shallow depth, to provide a
sufficient ventilation area.
If the ducts cannot be made lower,
place the SSR on a metal base so
that it is not surrounded by the ducts.
