Simple wiring using screw-less terminals
Easy and reliable installation and maintenance
When the conventional model with terminals on the top and bottom of the unit is installed in a small control
panel, it is difficult to secure sufficient space for wiring. The screw-less terminals on the front of the G9SE
make installation easier and much quicker.

Faster troubleshooting with status indicators
The indicators of conventional safety relay units only indicate the operating status of the internal relays (K1/K2), and it is difficult to
check the operation or connection of safety input devices. The new intuitive LED indicators of the G9SE show the operating status of
safety inputs and outputs, enabling faster and more accurate troubleshooting when the equipment stops.

Evaluate whether devices used are appropriate to
satisfy the requirements of safety category level.
Precautions for Safe Use
(1) Use G9SE within an enclosure with IP54 protection or higher of
IEC/EN60529.
(2) When ready for wiring, the power source shall be disconnected the
terminals in order to prevent an electrical shock.
(3) Do not apply any excessive voltage or current to the input or output
circuit the G9SE. Doing so may result in damage to the G9SE or
cause a fire.
(4) Incorrect wiring may lead to loss of safety function. Wire
conductors correctly and verify the operation of G9SE before
commissioning the system in which G9SE is incorporated.
(5) Do not apply DC voltages exceeding the rated voltages, or AC
voltages to G9SE.
(6) Use SELV/PELV DC supply satisfying requirements below to
prevent electric shock.
- DC power supply with double or reinforced insulation, for
example, according to IEC/EN60950 or EN50178 or a transformer
according to IEC/EN61558.
- DC supply satisfies the requirement for class 2 circuits stated in
UL 508.
(7) The lifetime of G9SE depends on the conditions of switching of its
outputs. Be sure to conduct its test operation under actual
operating conditions in advance and use it within appropriate
switching cycles. Apply protection circuitry against back
electromotive force in case connecting inductive loads to safety
outputs.
(8) Do not operate the G9SE with flammable or explosive gas.
An arc with operation and the heat of relay will cause a fire or an
explosion.
(9) Do not drop G9SE to the ground or dismantle, repair, modify
G9SE, otherwise an electric shock may occur or the G9SE may
malfunction. It may lead to loss of its safety functions.
(10) Use protective device (Fuse etc.) for short-circuit protection and
ground fault protection, otherwise a fire may occur or the G9SE
may malfunction.
(11) Auxiliary monitoring outputs are NOT safety outputs. Do not use
auxiliary outputs as any safety output.
Such incorrect use causes loss of safety function of G9SE and
its relevant system.
(12) After installation of G9SE, qualified personnel shall confirm
operations and maintenance.
The qualified personnel shall be qualified and authorized to
secure the safety on each phases of design, installation, running,
maintenance and disposal of system.
(13) A person in charge, who is familiar to the machine in which G9SE
is to be installed, shall conduct and verify the installation.
(14) Perform daily and 6-month inspections for the G9SE. Otherwise,
the system may fail to work properly,resulting in serious injury.
Turn OFF the signal to Safety input and make sure G9SE
operates without fault by checking the state of the LED indicator
in inspection.
(15) Conformity to requirements of performance level is determined
as an entire system. It is recommended to consult a certification
body regarding assessment of conformity to the required safety
level.
(16) OMRON shall not be responsible for conformity with any safety
standards regarding to customer's entire system.
(17) Dispose of the Units according to local ordinances as they apply.
G9SE
Precautions for Correct Use
(1) Handle with care
Do not drop G9SE to the ground or expose to excessive vibration
or mechanical shocks. G9SE may be damaged and may not
function properly.
(2) Adhesion of solvent such as alcohol, thinner, trichloroethane or
gasoline on the product should be avoided. Such solvents make
the marking on G9SE illegible and cause deterioration of parts.
(3) Conditions of storage
Do not store in such conditions stated below.
1. In direct sunlight
2. At ambient temperatures out of the range of -10 to 55 °C
3. At relative humidity out of the range of 25% to 85% or under
such temperature change that causes condensation.
4. At atmospheric pressure out of the range 86 to 106 kPa.
5. In corrosive or combustible gases
6. With vibration or mechanical shocks out of the rated values.
7. Under splashing of water, oil, chemicals
8. In the atmosphere containing dust, saline or metal powder and
other conductive dusts.
G9SE may be damaged and may not function properly.
(4) At least 50 mm above top face of G9SE and below bottom face of
G9SE should be available to apply rated current to outputs of
G9SE and for enough ventilation.
(5) Mounting multiple units
When mounting multiple units close to each other, the rated
current will be 3 A. Do not apply a current higher than 3 A. If the
output current is 3 A or more, make sure that there is a minimum
distance of 10mm each between all adjacent G9SE units.
(6) DIN rail mounting
Mount G9SE to DIN rails with attachments (TYPE PFP-M, not
incorporated to this product), not to drop out of rails by vibration
etc. especially when the length of DIN railing is short compared to
the widths of G9SE.
(7) Wire correctly according to Wiring.
(8) Use cables with length less than 100 m to connect to Safety
Inputs, Feed-back/Reset inputs, respectively.
(9) G9SE may malfunction due to electro-magnetic disturbances. Be
sure to connect the negative terminal of DC power supply to
ground. When using a DC power supply with light curtains, use DC
power supply which has no interruption by a power failure of
20 ms.
(10) This is a class A product. In residential areas it may cause radio
interference, in which case the user may be required to take
adequate measures to reduce interference.
(11) Do NOT mix AC load and DC load to be switched in the following
terminals.
- G9SE-201 : between 13-14 terminal and 23-24 terminal
- G9SE-401 : between 13-14 terminal and 23-24 terminal,
33-34 terminal and 43-44 terminal
- G9SE-221-T@ : between 13-14 terminal and 23-24 terminal,
37-38 terminal and 47-48 terminal
(12) Start entire system after more than 2s have passed since
applying supply voltage to G9SE.
(13) Set the time duration of OFF-delay (Type G9SE-221-T@)
1. Set the time duration of OFF-delay to an appropriate value that
does not cause the loss of safety function of system.
2. Set both of the two O on the front and back, to the same value.
When setting the de After setting, make sure G9SE operating
time is correct.
(14) To determine safety distance to hazards, take into account the
delay of Safety outputs caused by the following time:
1. Response time
2. Preset off-delay time and accuracy of off-delay time
(15) Before G9SE outputs become in ON-state, non-regular
self-diagnosis for Safety output circuit may be executed.
On this occasion, the operating noise of internal relays occurs.
(16) In the place subjected to strong vibration or shock, mount G9SE
to a mounting surface with screws and the screw mounting
attachment.
Otherwise, G9SE may not function properly due to vibration or
mechanical shocks out of the rated values caused by
sympathetic vibration of G9SE and the mounting parts,
and so on.
