NOTE
The direct current power supply to combine should be UL1310 Class2
power supply when conformity to UL is necessary.
Caution
When handling, assembling or replacing the unit:
•Avoid touching any sharp metal parts of the connectors for connecting
units.
•When assembling units, take care not to get any fingers caught
between units. Injury can result.
•When disassembling units, take care to avoid excessive force.
The connection parts of the unit are firmly joined with seals and injury
can result.
After maintenance is complete, perform appropriate functional
inspections.
Stop operation if the equipment does not function properly.
Safety cannot be assured in the case of unexpected malfunction.
Provide grounding to assure the safety and noise resistance of
the Fieldbus system.
Individual grounding should be provided close to the product with a
short cable.
Safety Instructions (Continued) Assembly
Assembling the unit as a manifold
(1) Connect a unit to the end plate.
Digital and Analogue I/O units can
be connected in any order.
Tighten the joint brackets to a
torque of 1.5 to 1.6 Nm.
(2) Add more I/O units.
Up to 10 units (including the SI unit)
can be connected to one manifold.
(3) Connecting the SI unit.
After connecting the required I/O
units, connect the SI unit.
The method is as above in (1), (2).
(4) Mounting the valve plate.
Mount the valve plate
(EX600-ZMV ) to the valve
manifold using the valve set
screws. (M3x8)
Apply 0.6 to 0.7 Nm tightening
torque to the screws.
(5) Connect the SI unit to the valve manifold.
Insert the valve
plate into the valve
plate mounting
groove on the side
of the SI unit.
Fix using the valve
plate screws
(M4x6) supplied, to a torque of 0.7 to 0.8 Nm.

Installation
•Direct mounting
(1) When joining six or more
units, fix the middle part of
the complete EX600 unit with
an intermediate reinforcing
brace (EX600-ZMB1) before
mounting, using 2-M4x5
screws.
Tightening torque:
0.7 to 0.8 Nm.
(2) Mount and tighten the end
plate at one end of the unit. (M4)
Tightening torque: 0.7 to 0.8 Nm.
Fix the end plate at the valve side while referring to the operation
manual of the corresponding valve manifold.

•DIN rail mounting
(Not available for SY series
valves. Refer to the SY
catalogue.)
(1) When joining six or more
units, fix the middle part of
the complete EX600 unit
with an intermediate
reinforcing brace
(EX600-ZMB2) before
mounting, using 2-M4x6 screws.
Tightening torque: 0.7 to 0.8 Nm.
(2) Mount the end plate bracket
(EX600-ZMA2) to the end plate at
the opposite end to the valves, using
2-M4x14 screws.
Tightening torque: 0.7 to 0.8 Nm.

(3) Hook the DIN rail mounting
groove on to the DIN rail.
(4) Press the manifold using its
side hooked to the DIN rail
as a fulcrum until the
manifold is locked.

(5) Fix the manifold by tightening
the DIN rail fixing screws
of the EX600-ZMA2. (M4x20)
Tightening torque:
0.7 to 0.8 Nm.
The tightening torque at the
valve side depends on the
valve type.
Refer to the operation manual of
the corresponding valve manifold.
Wiring
•Connect the M12 connector cable.
The M12 SPEEDCON connector connection method is explained
below.
(1) Align mark B on the metal bracket of the cable connector
(plug/socket) with mark A.
(2) Align with mark C on the unit and insert the connector vertically.
If they are not aligned, the connector cannot be connected
correctly.
(3) When mark B has been turned 180 degrees (1/2 turn), wiring is
complete. Confirm that the connection is not loose. If turned too
far, it will become difficult to remove the connector.
•Identification marker
The signal name of the input or output
devices and unit address can be written
on the marker, and can be installed on
each unit.
Mount the marker (EX600-ZT1) into the
marker groove as required.
