■ 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.
a. In direct sunlight
b. At ambient temperatures out of the range of − 10 to 55 ° C.
c. At relative humidity out of the range of 25% to 85% or under
such temperature change that causes condensation.
d. In corrosive or combustible gases
e. With vibration or mechanical shocks out of the rated values.
f. Under splashing of water, oil, chemicals
g. 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 the Advanced Unit (G9SX-
AD322-@-@/G9SX-ADA222-@-@) and side faces of the Basic
Unit (G9SX-BC202-@).
b. At least 50 mm above top face of G9SX and below bottom face
of G9SX.

5. Wiring
a. For model G9SX-@-RT (with screw terminals)
• Use the following to wire to G9SX-@-RT.
Solid wire
Stranded wire
(Flexible wire)
• Tighten each screw with a specified torque of 0.5 to 0.6Nm,
or the G9SX may malfunction or generate heat.
• Strip the cover of wire no longer than 7mm.
b. For model G9SX-@-RC (with spring-cage terminals)
• Use the following to wire to G9SX-@-RC
Solid wire
Stranded wire
• It is recommended that stranded wire should be terminated
with insulation-covered bar terminal (DIN 46228-4 standard
compatible type) at its ends before using for connection.

6. When connecting Expansion Units (G9SX-EX@-@) to Advanced
Unit (G9SX-AD322-@-@/G9SX-ADA222-@-@):
a. Follow the procedure below:
• Remove the termination connector from the receptacle on
Advanced Unit,
• Insert the head of the connecting cable of Expansion Unit to
the receptacle on the Advanced Unit
• 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.
b. Do not remove the termination connector or the connecting
cable of the Expansion Unit while the system is operating.
c. Before applying supply voltage, confirm that the connecting
sockets and plugs are locked firmly.
d. 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:
a. 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.
b. Connect Logical connection outputs appropriately to Logical
AND connection inputs of the relevant unit. Verify the operation
of G9SX before commissioning the system.
c. 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:
a. Response time of Safety inputs
b. Response time of Logical AND connection input
(See also "Ratings and specifications, note 5.")
c. Preset off-delay time
d. 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. To suppress electrical
noise, apply a surge absorber to the coil of inductive load.
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.Do NOT mix AC load and DC load to be switched in one G9SX-
EX@-@. When switching of both AC load and DC load is
necessary, connect more than two G9SX-EX@-@ and use each
unit for AC load and DC load exclusively.
