General Precautions; Correct Use - Omron G3PB Manual

G3PB Common
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.
! 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 differences 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 Tracks
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.
