Precautions
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.
WARNING
WARNING
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.
WARNING
Do
not touch main circuit terminal of the G3PB immediately
af
-
ter
the G3PB is turned OFF
, otherwise an electric shock may
be
received due to the residual charge of the built-in snubber
circuit.
WARNING
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.
WARNING
Ensure that a short-circuit current does not flow on the load
side
of the SSR, otherwise the G3PB may be damaged.
General Precautions
At OMRON, we are constantly working to improve the quality and
reliability of our products. SSRs, however, use semiconductors,
which are prone to malfunction. Be sure to use SSRs within their
rated
values.
Use
the
SSR only in systems that are designed with redundancies,
flame
protection, counter measures to prevent operation errors, and
other
countermeasures to prevent accidents involving human life or
fires.
1. Do
not apply voltages or currents to the G3PB’
s terminals in
excess
of the rated values. Doing so may result in malfunction
or
burning.
2. Do not use the G3PB with terminal screws not properly
tightened. Abnormal heating of the terminals may result in
burning.
3. Do not obstruct the flow of air around the G3PB and the
radiator. Abnormal heating of the G3PB may result
short-circuiting
of output elements and burning.
4. Perform wiring and tighten screws according to the
instructions given under
Correct Use
. Using the G3PB with
incorrect
wiring or with the screws not
tightened properly may
result
in burning due to abnormal heating of the G3PB during
use.
Correct Use
Before 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 consider dif
ferences in
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.
Mounting Method
Since the Relay is heavy, firmly mount the DIN track and fix both
ends
with End Plates for DIN-track-mounting models.
Applicable DIN T
racks
The
G3PB can be mounted to TH35-15Fe (IEC60715) DIN
tracks.
The manufacturers and models of DIN tracks to which mounting is
possible
are shown in the following table.
