Precautions

Refer to pages 11 to 19 for general precautions.

Load Connection

For an AC load, use a power supply rated at 50 or 60 Hz.
The maximum operating frequency is 10 Hz.
The G3NA has a built-in varistor for overvoltage protection.

Zero Cross Function

An SSR with a zero cross function operates when an AC load volt-
age reaches the zero point or its vicinity. This reduces clicking
noises when the load is input, and minimizes the influence of an in-
ductive load, such as a lamp, heater, or motor, on the power supply
because the inrush current of the load is reduced. This can also
minimize the scale of the inrush current protection circuit.

Output (load voltage)

Input

ON
OFF

At a low applied voltage, such as 24 VAC, the load current is not fully
supplied. When the Unit is switched ON, the voltage required to
power the Unit deprives the output signal of the necessary voltage
level and thus creates loss time. The lower the load voltage is, the
greater the loss time is. This condition, however, will not create any
serious problems.

Loss time

For a DC or L load, a diode should be connected in parallel the load
to absorb the counter electromotive force of the load.

When attaching a heat sink to the G3NA, apply Silicone Grease or
equivalent heat conductive grease on the heat sink. (Toshiba Sili-
con, Shinetsu Silicon, etc.)

Tighten the mounting screws of the heat sink with a torque of 0.78 to
0.98 N

EN55011 Measurement of Mains Terminal Disturbance

�

The output terminal side of the G3NA-D210B is connected to a built-
in diode for protecting the SSR from damage that may result from
reverse connection. The SSR, however, cannot withstand one min-
ute or more if the wires are connected in reverse order. Therefore,
pay the utmost attention not to make polarity mistakes on the load
side.
