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 should be disconnected rst. Further, at operating this unit, do not touch
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 re.
(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 DC supply satisfying requirements below to prevent electric shock.
- DC power supply with double or reinforced insulation, for example, according to IED/EN60950 or EN50178 or
a transformer according to IEC/EN61558.
- DC supply satis es the requirement for class 2 circuits or limited voltage/current circuit 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 ammable or explosive gas. An arc with operation and the heat of relay will cause
a re 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 re 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, quali ed personnel should con rm the installation, and should conduct test
operations and maintenance.
The quali ed personnel should be quali ed 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, should 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 certi cation 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.

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 ℃
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.
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 8 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 -delay Time Preset Switches, one each
on the front and back, to the same value. When setting the
di erent value, it is detected as a fault.
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 o -delay time and accuracy of o -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.
