<G9SX-GS@>
1. Be sure to correctly connect safety input devices to safety input A
and safety input B to ensure proper operation of the safety
functions.
2. When setting the Switching Function, be sure to consider safety
control requirements, safety level and safety category of the entire
system.
3. A qualified personnel who has a thorough understanding of the
installed machine must switch the mode selector input. For
example, a Switching Unit with Key must be used for the mode
selector, and the key must be managed and used in such a way
that the machine cannot be operated by unauthorized persons.
<G9SX-EX@>
1. The durability of relays depend greatly on the switching condition.
Confirm the actual conditions of operation in which the relay will be
used in order to make sure of the permissible number of switching
operations.
Precautions for Correct Use
<Precautions for All G9SX Models>
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
G9SX may be damaged and may not function properly.
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.
3. Mounting
Mount G9SX to DIN track with attachments (PFP-M, not
incorporated to this product), not to drop off the track by vibration
or other force especially when the length of DIN track 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:
1. At least 25 mm beside side faces of the G9SX.
2. At least 50 mm above top face of G9SX and below bottom face
of G9SX.

5. Wiring
(1) G9SX
• Wire the G9SX as described below.
Solid wire 0.2 to 2.5 mm
Stranded wire 0.2 to 2.5 mm
• Strip no more than 7 mm of insulation from the end of the
wire.
(2) G9SX-@-RT (with Screw Terminals)
• Tighten each screw to 0.5 to 0.6 N·m or the G9SX-@-RT
may malfunction or generate heat.
(3) Wiring for a Logical AND Connection
• Use a 2-conductor cabtire cable or shielded cable to wire a
logical AND connection between Units.
6. Connecting Expansion Units (G9SX-EX@-@):
(Only G9SX-AD@/-ADA@/-NSA@/-GS@)
(1)Remove the termination connector from the G9SX, and insert
the connector of the Expansion Unit into the G9SX to connect
it.
(2)Insert the termination connector into the last Expansion Unit as
viewed from the G9SX. When the G9SX is used without any
Expansion Units, do not remove the termination connector
from the G9SX.
(3)Do not remove the termination connector while the system is
operating.
(4)Before applying the power supply voltage, confirm that the
connecting sockets and plugs are locked.
(5)Make sure that all connected Expansion Units are supplied with
power within 10 s after the power to the G9SX is turned ON.
Otherwise, the G9SX will detect a power supply error for the
Expansion Units.
7. Use cables with a length of 100 m maximum to connect the safety
inputs, feedback/reset input, logical AND connection input, logical
AND connection output, or mode selector inputs.
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 AND connection between Units
1. When using Logical AND connection inputs, set the Logical
AND connection preset switch to 'AND' position for the units
which the logical AND connection signal are input to.
2. Connect Logical AND connection outputs appropriately to
Logical AND connection inputs of the relevant unit. Verify the
operation of G9SX before commissioning the system.
3. Give careful consideration to the response time delay during
logical AND connection in order to prevent any reduction in the
safety of the safety control system.
4. Use two-conductor cabtyre cable or shielded cable for wiring
the logical AND connections between Units.
10. To determine the safety distance to hazards, take into account the
delay of safety outputs caused by the following times:
(1) Response time of safety inputs
(2) Response time of logical AND connection input
(Also consider the precaution in " * " below)
(3) Preset OFF-delay time
(4) Accuracy of OFF-delay time
* When connecting multiple Units with logical AND connections, the
operating time and response time after logical AND connection
inputs will be the sum of the operating times and response times of
the Units that are connected in series by logical AND connections.
