Warning• A semiconductor is used in this instrument. Take note that in general semiconductors sometimes malfunction.
• As a result of malfunction when using this SSR, injuries, fire or social damage may occur.
Therefore system safety designs such as a redundancy, fire control and prevention and malfunction
contingency must be provided and implemented.
• Do not use this SSR if any terminal screw is not tightened securely. Otherwise the unit may be burnt out due toabnormal heating of the terminal section.
• Do not apply overvoltage or overcurrent to the input or output circuit of this unit. A malfunction or burnout
may occur.

Caution with respect to Export Trade Control Ordinance
To avoid this instrument from being used as a component in, or as being utilized in the manufacture of weaponsof mass destruction (i.e. military applications, military equipment, etc.), please investigate the end users and thefinal use of this instrument. In the case of resale, ensure that this instrument is not illegally exported.

2. Mounting to the control panel
2.1 Site selection

CautionUse within the following temperature and humidity ranges.
Temperature:-10 to 50 (14 to 122 ), Humidity: 45 to 85%RH (No icing, no condensation)
If the SA-400 is installed within the control panel, the ambient temperature of the SA-400 must be kept
to under 50 . Otherwise the life of electronic parts of this unit will be shortened.
Ensure the mounting location corresponds to the following conditions:• A minimum of dust, and an absence of corrosive gases• No flammable, explosive gases• Few mechanical vibrations or shocks• No exposure to direct sunlight, an ambient temperature of -10 to 50 (14 to 122 ) that does notchange rapidly• An ambient non-condensing humidity of 45 to 85%RH• No large capacity electromagnetic switches or cables through which large current is flowing• No water, oil or chemicals or where the vapors of these substances can come into direct contact withthe controller

Obstacles to air circulation

Obstacles to air circulation(Fig. 2.3-8)(Fig. 2.3-7)• When mounting units above and below each other, keep a space of more than 80mm between them.
• As the SA-400 is heavy, fix the unit with end plates after securely mounting on the DIN rail.
• For close mounting, reduce the rated load current.
For details, refer to “Load current and ambient temperature characteristics” of “4. Specifications”.

3. Wiring
3.1 Wiring examples

Warning
Turn the power supply to the instrument off before wiring. Working or touching the terminal with the powerswitched on may result in severe injury or death due to Electric Shock.
• Do not touch this unit and heat sink during power-on or immediately after power-off.
Burns may be caused as the unit and heat sink become very hot.
• Do not touch output terminals during power-on or immediately after power-off. Electric shock may be caused
due to the built-in snubber circuit which has been electrically-charged.
• Do not block air circulation around the unit and heat sink. Interference may result in a short circuit fault
or burnout due to abnormal heat from the unit.
• Be sure not to flow the short circuit current on the load side. If it flows, the SA-400 may break.
• To prevent damage to peripheral devices or equipment caused by malfunction of the SA-400,
be sure to take safety measures such as applying a fuse before using this unit.
