Precautions
■ General Precautions
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 electric 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 touch-
ing the terminals of the SSR, otherwise an electric shock
may be received.
■ 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.
■ 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.
