Precautions
WARNING
Do not touch the terminals (i.e., charged parts) of the G3PB
while power is supplied, otherwise an electric shock may be
received.
If the G3PB is provided with a terminal cover, be sure to attach
the terminal cover to the G3PB before operating the G3PB.
The G3PB and radiator are very hot while power is supplied to
the G3PB.
Do not touch the G3PB or the radiator while power is supplied
to the G3PB or immediately after the G3PB is turned OFF,
otherwise a burn may result.
Do not touch the load terminal of the G3PB immediately after
the G3PB is turned OFF, otherwise an electric shock may be
received due to the residual charge of the built-in snubber cir-
cuit.
Be sure to turn OFF the power supply to the G3PB before wir-
ing, otherwise an electric shock may be received.
Mount the terminal cover to the G3PB after wiring.
Do not touch the terminals of the G3PB while power is sup-
plied, otherwise an electric shock may be received.
The built-in capacitor will be charged as long as power is sup-
plied. Do not touch the terminals of the G3PB unless the G3PB
is turned OFF and the built-in capacitor discharges all of its re-
sidual voltage, otherwise an electric shock may result.
Caution
Do not apply excessive voltage or current to the input or output
circuit of the G3PB, otherwise the G3PB may malfunction or
burn.
Do not use the G3PB unless all the output terminal screws are
tightened securely, otherwise the terminals may generate ex-
cessive heat and the G3PB may burn.
Be sure to provide enough ventilation to the G3PB and the ra-
diator, otherwise the G3PB may generate excessive heat and
the G3PB may burn or the output element may short-circuit.
Be sure to turn OFF the power supply to the G3PB before wir-
ing, otherwise an electric shock may be received.
Be sure to wire or solder the terminals of the G3PB properly,
otherwise the G3PB may generate excessive heat and burn.
If the G3PB is mounted directly to a control panel that is used
as a radiator as well, the control panel must be made of alumi-
num or a steel plate with low thermal resistance.
Do not use any material with high thermal resistance, such as
a wooden plate, otherwise the G3PB may catch on fire or burn.
JBEFORE ACTUAL OPERATION
•The G3PB in operation may cause an unexpected accident.
Therefore it is necessary to test the G3PB under a variety of
conditions that are possible. As for the characteristics of the
G3PB, it is necessary to take into consideration the dispersion
of the characteristics between G3PB Units.
•The ratings in this datasheet are tested values in a
temperature range between 15°C and 30°C, a relative
humidity range between 25% and 85%, and an atmospheric
pressure range between 88 and 106 kPa. It will be necessary
to provide the above conditions as well as the load conditions
if the user wants to confirm the ratings of actual G3PB Units.
JMOUNTING METHOD
Since the Relay is heavy, firmly mount the DIN track and fix both
ends with End Plates for DIN-track-mounting models.
For direct mounting, firmly mount the Relay on the panel.

Note: Make sure that the load current is 50% of the rated load cur-
rent when the G3PB is mounted horizontally.

Note: Be sure to provide a minimum space of 30 mm horizontally
and 60 mm vertically between adjacent Units.
