Safety Precautions for All G3PE Models
For common precautions, refer to Safety Precautions for All Solid-state Relays on page 1191.
Minor electrical shock may occasionally occur.
Do not touch the G3PE terminal section (i.e., current-
carrying parts) while the power is being supplied.
Also, always attach the cover terminal.
The G3PE may rupture if short-circuit current flows.
As protection against accidents due to short-
circuiting, be sure to install protective devices, such
as fuses and no-fuse breakers, on the power supply
side.
Minor electrical shock may occasionally occur.
Do not touch the main circuit terminals on the G3PE
immediately after the power supply has been turned
OFF. Shock may result due to the electrical charge
stored in the built-in snubber circuit.
Minor burns may occasionally occur.
Do not touch the G3PE or the heat sink while the
power is being supplied or immediately after the
power supply has been turned OFF. The G3PE and
heat sink become extremely hot.
OMRON constantly strives to improve quality and reliability.
SSRs, however, use semiconductors, and semiconductors may
commonly malfunction or fail. In particular, it may not be possible to
ensure safety if the SSRs are used outside the rated ranges.
Therefore, always use the SSRs within the ratings. When using an
SSR, always design the system to ensure safety and prevent human
accidents, fires, and social harm in the event of SSR failure. System
design must include measures such as system redundancy,
measures to prevent fires from spreading, and designs to prevent
malfunction.
Transport
Do not transport the G3PE under the following conditions.
Doing so may result in damage, malfunction, or deterioration of
performance characteristics.
• Conditions in which the G3PE may be subject to water.
• Conditions in which the G3PE may be subject to high temperature
or high humidity.
• Conditions in which the G3PE is not packaged.
Operating and Storage Environments
Do not use or store the G3PE in the following locations. Doing so may
result in damage, malfunction, or deterioration of performance
characteristics.
• Locations subject to rainwater or water splashes.
• Locations subject to exposure to water, oil, or chemicals.
• Locations subject to high temperature or high humidity.
• Do not store in locations subject to ambient storage temperatures
ou
tside the range −30 to 100°C.
• Do not use in locations subject to relative humidity outside th
e
range 45% to 85%.
• Locations subject to corrosive gases.
• Locations subject to dust (especially iron dust) or salts.
• Locations subject to direct sunlight.
• Locations subject to shock or vibration.
Installation and Handling
• Do not block the movement of the air surrounding the G3PE or heat
sink. Abnormal heating of the G3PE may result in shorting failures
of the output elements or burn damage.
• Do not use the G3PE if the heat radiation fins have be
en bent by
being dropped. Doing so may result in ma
lfunction due to a
reduction in the hea
t radiation performance.
• Do n
ot handle the G3PE with oily or dusty (especially iron du
st)
hands. Doing so may result in malfunction.
• Attach a heat sink or radiator when using an SSR. Not doing so
may result in ma
lfunction due to a reduction in t
he heat radiation
performance.
Installation and Mounting
• Mount the G3PE in the specified direction. Otherwise excessive
heat genera
ted by the G3PE may cause short-circuit failures of the
output elements or burn damage.
• Make sure that there is no excess ambient temperature rise due to
the heat generation of the G3PE. If the G3PE is mounted inside
a
panel, install a fa
n so that the interior of the panel is fully ventilated.
• Make sure the DIN track is securely mou
nted. Otherwise, the
G3PE may fall.
• When mounting the heat sink, do not allow any foreign matter
betw
een the heat sink and the mounting surface. Foreign matte
r
may ca
use malfunction due to a reduction in t
he heat radiation
performance.
• If the
G3PE is mou
nted directly in a control panel, use aluminum,
steel plating, or similar material
with a low heat resistance as
a
substitute
for a heat sink. Using the G3PE mounted in
wood or
other material with a high heat resistance may result in fire or
burning
due to heat generated by the G3PE.
Installation and Wiring
• Use wires that are suited to the load current. Otherwise, excessive
heat generated by the wires may cause burning.
• Do not use wires with a damaged outer covering.
Otherwise, it may result in electric shock or ground leakage.
• Do not wire any wiring in the sa
me duct or conduit as power or
high-ten
sion lines. Otherwise, inductive noise may dama
ge the
G3PE or cause it t
o malfunction.
• When tightening terminal screws, prevent any non-conducting
material from becoming caught between the screws and the
tightening surface. Otherw
ise, excessive heat generated by the
terminal may cause burning.
• Do not use the G3PE with loose terminal screws. Otherwise,
excessive heat generated by the wire may cause burning.
• For the G3PE models with a carry current of 35 A or larger, use M5
crimp terminals that are an appropriate size for the diameter of the
wire.
• Always turn OFF the power supply before performing wiring
. Not
doing so may cause electrical shock.
Installation and Usage
• Select a load within the rated values. Not doing so may result in
malfunction, failure, or burning.
• Select a power supply within the rated frequencies. Not doing so
may result in malfunction, failure, or burning.
• If a surge voltage is applied to the load of the Contacto
r, a surge
bypass(*) will functio
n to trigger the output element.
The G3PE
therefore cannot
be used for motor loads. Doing so may resu
lt in
load motor malfu
nction.
* Surge Bypass
This circuit protects the output circuit from being destroyed. T
his
su
ppresses the surge energy applied inside the SSR in comparison
with a varistor for the main circuit protection. By alleviating electrical
stress on the electronic components of the SSR's output circui
t,
failure and destruction due to surge voltage are suppressed.
Reference value: Surge dielectric strength of 30
kV min.
(Test conditions: 1.2 ✕ 50 μ s standard voltage waveform, peak voltage
of 30 kV, repeated 50 times according to JIS C5442)
