Precautions
General Precautions
Be sure to turn off power to the SSR before wiring the SSR, other-
wise an electric shock may be received.
Do not touch the terminals of the SSR while power is being sup-
plied to the SSR. The terminals are charged with the power, and an
electric shock may be received by touching the terminals.
The built-in capacitor may have residual voltage after the SSR is
turned off. Be sure to discharge the residual voltage before touching
the terminals of the SSR, otherwise an electric shock may be re-
ceived.
Mounting
1. Make sure that no excessive voltage or current is imposed on or
flows to the input or output circuit of the SSR, otherwise the SSR
may malfunction or burn.
2. Solder the terminals of the SSR properly under the required sol-
dering conditions. The SSR may be abnormally heated and
burn if power is supplied to the terminals soldered incorrectly.
3. Do not short-circuit the load of the SSR while power is supplied
to the SSR. Do not short-circuit the power supply through the
SSR. The SSR may be damaged, malfunction, or burn if the
load or power supply is short-circuited.
Correct Use
The terminals of the SSR are highly heat-conductive. Each terminal
must be soldered within 10 s at 260_C or within 5 s at 350_C.
The SSR is of a thin-profile construction. To maintain the vibration
resistance of the SSR, make sure that the space between the SSR
and PCB is 0.1 mm maximum. Lifting of the PCB can be prevented
by setting the hole diameter of the PCBs on both sides slightly
smaller than the actual terminal dimension.
Select the model without the zero-cross function when using the
Unit for phase control output.
The casing works as a heat sink. When mounting two or more Units
closely, make sure that the Units are properly ventilated by taking
ambient temperature rises into consideration. If Units are closely
mounted and used in places with no ventilation, the load current of
each Unit must be 1/2 of the rated load current.
Fusing Characteristics
The G3MC has a function that forces an open mode failure when an
overcurrent exceeds the rated value. The fusing characteristics of
the G3MC, however, are not the same as those of a general-use
glass fuse. Machines that use the G3MC must be provided with a
safety device, such as a fuse or breaker, and ON-OFF tests or short-
circuit tests must be implemented to confirm the following items and
detailed influences. Users must determine test conditions and im-
plement tests on reliability as required by the machine.
1. Life test under continuous electric current
2. On-off cycle test
3. Influence by ambient temperature
4. Influence by power source frequency
5. Influence by power source voltage fluctuation
Note: Contact your local OMRON sales office for more detailed
information.
Protective Element
No overvoltage absorption element is built in. Therefore, if the
G3MC is connected to an inductive load, be sure to connect the
overvoltage absorption element.
