Precautions for Safe Use
(1) Use G9SX within an enclosure with IP54 protection or higher of IEC/EN60529
(2) Incorrect wiring may lead to loss of safety function. Wire conductors correctly
and verify the operation of G9SX before commissioning the system in which
G9SX is incorporated.
(3) Do not apply DC voltages exceeding the rated voltages, nor any AC voltages
to G9SX. Do not connect to DC distribution network.
(4) 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 tranceformer according to
IEC/EN61558.
- DC supply satisfies the requirement for class 2 circuits orlimited
voltage/current circuit stated in UL 508.
(5) Apply properly specified voltages to G9SX inputs.
Applying inappropriate voltages cause G9SX to fail to perform its specified
function, which leads to the loss of safety functionsor damages to G9SX
(6) Auxiliary error outputs and 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 G9SX and its relevant system.
Also Logical connection outputs can only be used for logical connections
between G9SXs.
(7) After installation of G9SX, qualified personnel should confirm the installation,
and should conduct test operations and maintenance.
The qualified personnel should be qualified and authorized to secure the
safety on each phases of design, installation, running, maintenance and
disposal of system.
(8) A person in charge, who is familiar to the machine in which G9SX is to be
installed, should conduct and verify the installation.
(9) Turn OFF the signal to Safety input or Logical AND connection input every
24hours and make sure G9SX operates without faults by checking the state
of the ERR indicator.
(10) Do not dismantle, repair, or modify G9SX. It may lead to loss of its safety
functions.
(11) Use only appropriate components or devices complying with relevant safety
standards corresponding to the required level of safety categories.
Conformity to requirements of safety category is determined as an entire system.
It is recommended to consult a certification body regarding assessment of
conformity to the required safety level.
(12) OMRON shall not be responsible for conformity with any safety standards
regarding to customer's entire system.
(13) Disconnect G9SX from power supply when wiring. Devices connected to
G9SX may operate unexpectedly.
(14) Be cautious not to have your fingers caught when attaching terminal sockets
to the plugs on G9SX.
Precautions for Correct Use
(1) Handle with care
Do not drop G9SX to the ground or expose to excessive vibration or
mechanical shocks. G9SX may be damaged and may not function properly.
(2) 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) In corrosive or combustible gases
5) With vibration or mechanical shocks out of the rated values.
6) Under splashing of water, oil, chemicals
7) In the atmosphere containing dust, saline or metal powder.
G9SX may be damaged and may not function properly.
(3) Mounting
Mount G9SX 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 G9SX.
(4) Following spacing around G9SX should be available to apply rated
current to outputs of G9SX and for enough ventilation and wiring:
a) At least 25 mm beside side faces of G9SX.
b) At least 50 mm above top face of G9SX and below bottom face of G9SX.

(5) Wiring
1) For model G9SX- 
Use the following to wire to G9SX-  .
-Solid wire: 0.2 to 2.5mm AWG24 to AWG12
2
-Stranded wire (Flexible wire): 0.2 to 2.5mm 2 AWG24 to AWG12
Strip the cover of wire no longer than 7mm.
2) For model G9SX-  -RT (with screw terminals)
Tighten each screw with a specified torque of 0.5 to 0.6N·m, or the
G9SX-  may malfunction or generate heat.
3) For Logical AND Connection
Use VCTF cable or shielded cable for Logical AND connection
between units.
(6) When connecting Expansion Units (G9SX-EX  -  ) to Advanced Unit:
1) Follow the procedure below:
a) Remove the termination connector from the receptacle on
Advanced Unit,
b) Insert the head of the connecting cable of Expansion Unit to the
receptacle on the Advanced Unit
c) Set the termination connector to the receptacle on the Expansion Unit
at the end position. When Advanced Unit is used without expansion
units, leave the termination connector set on the Advanced Unit.
2) Do not remove the termination connecter while the system is operating.
3) Before applying supply voltage, confirm that the connecting
sockets and plugs are locked firmly.
4) All of the Expansion Units should be supplied with its specified
voltages within 10s after the connected Advanced Unit is supplied
with voltage.
Otherwise, Advanced Unit detects the power-supply error for the
Expansion Units.
(7) Use cables with length less than 100m to connect to Safety Inputs,
Feed-back/Reset inputs, or between Logical AND connection inputs
and Logical connection outputs, respectively.
(8) Set the time duration of OFF-delay to an appropriate value that does
not cause the loss of safety function of system.
(9) Logical connection between Units:
1) When using Logical AND connection inputs, set the Logical
connection preset switch to 'AND' position for the units which the
logical connection signal are input to.
2) Connect Logical connection outputs appropriately to Logical AND
connection inputs of the relevant unit. Verify the operation of G9SX
before commissioning the system.
3) When configuring the safety related system, be sure to consider
that the delay of response time caused by logical connections do
not degrade the safety function of the system.
(10) To determine safety distance to hazards, take into account the delay
of Safety outputs caused by the following time:
1) Response time of Safety inputs
2) Response time of Logical AND connection input
(See also "Ratings and specifications, note5")
3) Preset off-delay time
4) Accuracy of off-delay time
(11) Start entire system after more than 5s have passed since applying
supply voltage to all G9SXs in the system.
(12) G9SX may malfunction due to electro-magnetic disturbances.
Be sure to connect the terminal A2 to ground.
When using a DC power supply with light curtains, use DC power
supply which has no interruption by a power failure of 20ms.
(13) Devices connected to G9SX may operate unexpectedly.
When replacing G9SX, disconnect it from power supply.
(14) Adhesion of solvent such as alcohol, thinner, trichloroethane or
gasoline on the product should be avoided. Such solvents make the
marking on G9SX illegible and cause deterioration of parts.
(15)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.
(16) Operate the reset input more than 0.4 seconds immediately after the
safety outputs are OFF.
G9SX does not accept the reset input from when the outputs are
turned ON and until 0.4 seconds passes after the outputs are turned
OFF.
