04.
Failure to follow this instruction may result in electric shock.
• Follow instructions in ‘Cautions during Use’. Otherwise, it may cause unexpected accidents.
• 4 - 30 VDCᜡ, 24 VACᜠ model supply should be insulated and limited voltage/current or
Class 2, SELV power supply device.
• Attach a heat sink or install the unit in the well ventilated place.
To attach the heat sink, use Thermal Grease as below or that of equal specication.
- Thermal Grease: GE TOSHIBA (YG6111), KANTO-KASEI (FLOIL G-600), SHINETSU (G746)
• Ground the heatsink, panel, or DIN rail. Failure to follow this instruction may result in
electric shock.
• While supplying power to the load or right after turning o the power of the load, do not
touch the body and heat sink. Failure to follow this instruction may result in burn due to
high temperature of the surface.
• In order to protect the product from the short-circuit current of the load, use rapid fuse of
which I
2
t is under the 1/2 of SSR I
2
t. When short-circuited, replace the fuse to those of same
specication with the used rapid fuse.
• Install dummy resistance in parallel with the load, to keep the sum of current owing in the
load and dummy resistance being over SSR minimum load current.
• When using random turn-on model for phase control, install noise lter between the load
and the power of the load.
• Do not use near the equipment which generates strong magnetic force or high frequency
noise.
• This unit may be used in the following environments.
- Indoors (in the environment condition rated in ‘Specications’)
- Altitude max. 2,000 m
- Pollution degree 2
- Installation category III

While supplying power to the load or right after turning o the power of the load,
do not touch the body and heat sink. Failure to follow this instruction may result in
burn due to high temperature of the surface.
• When installing multiple SSRs, be sure to keep space between SSRs for heat radiation.
• When installing SSRs horizontally (input part and output part on the same height),
be sure to supply less than 50 % of the rated load current.
• Autonics does not provide or sell a cooling fan. Buy directly a cooling fan.

• The heatsink of the curves is dedicated for the SRH2/SRH3.
• Install SR2 / SR3 Series on the metal plate (min. 130 × 120 mm).
• Be aware that the ambient temperature and the derating curve is dierent by the
rated input voltage when using the product.
• When installing multiple SSRs, be sure to keep space between SSRs for heat
radiation. When installing SSRs horizontally (input part and output part on the
same height), be sure to supply less than 50 % of the rated load current.
• SSR derating curves obtained approval from the UL certication authority.
