Safety Considerations

• Observe all 'Safety Considerations' for safe and proper operation to avoid hazards.
• ᜸ symbol indicates caution due to special circumstances in which hazards may
occur.
᜸ Warning
Failure to follow instructions may result in serious injury or death.
01. Fail-safe device must be installed when using the unit with machinery that
may cause serious injury or substantial economic loss.(e.g., nuclear power
control, medical equipment, ships, vehicles, railways, aircraft, combustion
apparatus, safety equipment, crime/disaster prevention devices, etc.)
Failure to follow this instruction may result in personal injury, economic loss or fire.
02. Do not use the unit in the place where flammable/explosive/corrosive gas,
high humidity, direct sunlight, radiant heat, vibration, impact or salinity
may be present.
Failure to follow this instruction may result in explosion or fire.
03. Install the unit on DIN rail or panel to use.
Failure to follow this instruction may result in fire or electric shock.
04. Do not connect, repair, or inspect the unit while connected to a power
source.
Failure to follow this instruction may result in fire or electric shock.
05. Check 'Connections' before wiring.
Failure to follow this instruction may result in fire.
06. Do not disassemble or modify the unit.
Failure to follow this instruction may result in fire or electric shock.
᜸ Caution
Failure to follow instructions may result in injury or product damage.
01. Use the unit within the rated specifications.
Failure to follow this instruction may result in fire or product damage.
02. Use a dry cloth to clean the unit, and do not use water or organic solvent.
Failure to follow this instruction may result in fire or electric shock.
03. Keep the product away from metal chip, dust, and wire residue which flow
into the unit.
Failure to follow this instruction may result in fire or product damage.
04. Since leakage current still flows right after turning off the power or in the
output OFF status, do not touch the load terminal.
Failure to follow this instruction may result in electric shock.
Cautions during Use
• 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 specification.
- 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 off 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 t is under the 1/2 of SSR I t. When short-circuited, replace the fuse to those of same
2 2
specification with the used rapid fuse.
• Install dummy resistance in parallel with the load, to keep the sum of current flowing in the
load and dummy resistance being over SSR minimum load current.
• When using random turn-on model for phase control, install noise filter 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 'Specifications')
- Altitude max. 2,000 m
- Pollution degree 2
- Installation category III
