Single-phase Solid State Relays for Heaters
G3PE
Safety Precautions
Refer to Safety Precautions for All Solid State Relays.
!
CAUTION
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 SSR
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 SSR or the heatsink while the power
is being supplied or immediately after the power
supply has been turned OFF. The SSR and heatsink
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 per-
formance 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
outside the range
−
30 to 100
°
C.
•
Do not use in locations subject to relative humidity outside the
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 been bent by
being dropped. Doing so may result in malfunction due to a
reduction in the heat radiation performance.
•
Do not handle the G3PE with oily or dusty (especially iron dust)
hands. Doing so may result in malfunction.
•
Attach a heat sink or radiator when using an SSR. Not doing so
may result in malfunction due to a reduction in the heat radiation
performance.
Installation and Mounting
•
Mount the G3PE in the specified direction. Otherwise excessive
heat generated 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 fan so that the interior of the panel is fully ventilated.
•
Make sure the DIN track is securely mounted. Otherwise, the
G3PE may fall.
•
When mounting the heat sink, do not allow any foreign matter
between the heat sink and the mounting surface. Foreign matter
may cause malfunction due to a reduction in the heat radiation
performance.
•
If the G3PE is mounted 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 same duct or conduit as power or
high-tension lines. Otherwise, inductive noise may damage the
G3PE or cause it to malfunction.
•
When tightening terminal screws, prevent any non-conducting
material from becoming caught between the screws and the
tightening surface. Otherwise, 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.
•
The G3PE provides a circuit to prevent photocoupler damage by
forcibly arcing the output element for surge voltages applied to the
load. The G3PE therefore cannot be used for motor loads. Doing
so may result in load motor malfunction.
