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 supplied
to the SSR. The terminals are charged with the power, and an elec-
tric shock may be received by touching the terminals.
The built-in capacitor may have a 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
soldering 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.
The load terminals are internally connected to a snubber circuit that
absorbs noise. However, if wiring from these terminals is laid with or
placed in the same duct as high-voltage or power lines, noise may
be induced, causing the SSR to operate irregularly or malfunction.
The SSR does not incorporate a circuit protecting the input circuit
from damage resulting from the wrong input polarity. Make sure that
the polarity of the input is correct.
If a surge voltage peaking at more than 250 V is imposed on the
G3MC-102PL or that peaking at more than 450 V is imposed on the
G3MC-202P(L), connect a varistor as a surge absorber in parallel to
the terminals of the load as shown in the following illustration.
