zSAFETY PRECAUTIONS z
(Read these precautions before using this product.)
Before using this product, please read this manual and the relevant manuals
carefully and pay full attention to safety to handle the product correctly.
The instructions given in this manual are concerned with this product. For the
safety instructions of the programmable controller system, please read the
CPU module user's manual.
In this manual, the safety precautions are classified into two levels:
"WARNING" and " CAUTION".
Under some circumstances, failure to observe the precautions given under
"CAUTION" may lead to serious consequences.
Observe the precautions of both levels because they are important for personal
and system safety.
Make sure that the end users read this manual and then keep the manual in a
safe place for future reference.
[DESIGN PRECAUTIONS]
WARNING
zInstall a safety circuit external to the programmable controller that keeps
the entire system safe even when there are problems with the external
power supply or the programmable controller main module.
An accident may occur by a false output or a malfunction.
Output could be left ON or OFF when there is trouble in the output
module's relay or transistor. So build an external monitoring circuit that
will monitor any signal output that could cause serious trouble.
zIn an output module, build a safety circuit such as a fuse externally of the
module, because there is a possibility of fire or smoke in the case when
overcurrent exceeding the rating flows continuously for a prolonged time
due to shorted load.
CAUTION
zDo not bunch the control wires or communication cables with the main
circuit or power wires, or install them close to each other. They should
be installed 100mm (3.9 in) or more from each other. Not doing so could
result in noise that would cause malfunction.

[INSTALLATION PRECAUTIONS]
CAUTION
zUse the module in the environment given in the general specifications of CPU
module user's manual.
Using the programmable controller outside the range of the general specifications
may result in electric shock, fire or malfunction, or may damage the product.
zLoad a cable by inserting to a module connector until a clicking sound comes.
Check any looseness after the loading. False connection may cause a mis-input
or mis-output.
zLoad a module by pressing against the DIN rail until a clicking sound comes.
Check any looseness after the loading. Improper installation may cause the
module to fall out, resulting in breakdowns.
zDo not directly touch the module's conductive parts or electronic components.
Doing so could cause malfunction or trouble in the module.
[WIRING PRECAUTIONS]
WARNING
zBefore beginning any installation or wiring work, make sure all phases of the
power supply have been obstructed from the outside.
Failure to completely shut off the power supply phases may cause electric shock
and /or damage to the module.
zWhen turning on the power or operating the module after installation or wiring
work, be sure the module's terminal covers are correctly attached.
Failure to attach the terminal covers may result in electric shock.
CAUTION
zWhen wiring the programmable controller, check the rated voltage and terminal
layout of the wiring, and make sure the wiring is done correctly. Connecting a
power supply that differs from the rated voltage or wiring it incorrectly may cause
fire or failure.
zTighten the terminal screws with the specified torque. If the terminal screws are
loose, it may result in short circuits, fire or malfunction. Tightening the screws too
far may cause damage to the screw and /or the module, resulting in short circuits,
fire or malfunction.
zBe sure there are no foreign substances such as sawdust or wiring debris inside
the module. Such debris could cause fire, failure or malfunction.
zBe sure to fix wires or cables leading from the module by placing them in the duct
or clamping them. Cables not placed in the duct or without clamping may hang or
shirt, allowing them to be accidentally pulled, which may result in a module
malfunction and cable damage.
zInstall our programmable controller in a control panel for use. Wire the main power
supply to the power supply module installed in a control panels through a
distribution terminal block.
Furthermore, the wining and replacement of a power supply module have to be
performed by a maintenance worker who acquainted with shook protection. (For
the wiring methods, refer to section 4.1)

[STARTING AND MAINTENANCE PRECAUTIONS]
WARNING
zDo not touch the terminals while the power is on. Doing so may cause electric
shock or malfunction.
zSwitch off all phases of the externally supplied power used in the system when
cleaning the module or retightening the terminal or module mounting screws.
Not doing so could result in electric shock.
Undertightening of terminal screws can cause a short circuit or malfunction.
Overtightening of screws can cause damages to the screws and/or the module,
resulting in fallout, short circuits, or malfunction.
[STARTING AND MAINTENANCE PRECAUTIONS]
CAUTION
zDo not disassemble or modify the modules. Doing so could cause failure,
malfunction, injury or fire.
zWhen detaching the communication cable or power cable from the module, do not
pull the cable portion. For cables with connectors, hold the connector at the
junction to the module, then detach it. For cables without connectors, first loosen
the screw at the junction, then detach the cable.
Pulling the cable portion while it is connected to the module may cause a
malfunction or damage to the module and cable.
zBe sure to shut off all phases of the external power supply used by the system
before connecting or disconnecting the cable.
Failure to do so may result in failure or malfunctions of the module
zBefore touching the module, always touch grounded metal, etc. to discharge static
electricity from human body, etc.
Not doing so can cause the module to fail or malfunction.
[DISPOSAL PRECAUTIONS]
WARNING
zWhen disposing of this product, treat it as industrial waste.

1. OVERVIEW
This User's Manual explains the specifications and part identification of A6TE2-16SRN
Relay Terminal Module (abbreviated as A6TE2-16SRN hereafter).
The A6TE2-16SRN is used in place of a joint terminal block and in-panel relay. It
reduces wiring work processes for the programmable controller, joint terminal block and
in-panel relay.
A6TE2-16SRN
1) The A6TE2-16SRN can be used in combination with sink type output modules
having the following connectors (only Fujitsu component Limited 40-pin
connector).

2) One cable (separate arrangement; see Figure 4.2) and two relay terminal
modules can share 32 points (one connector).
3) By using the dedicated cable, it is possible to install the relay terminal module in a
position of maximum 10 m (32.8 feet).
4) There are five types of dedicated cables, each having different cable length.
5) Because it is a socket-type relay, each relay can be replaced individually as
necessary.
yThe relay has a structure that allows secure installation and prevents drop-offs
due to vibration, etc.
yIt is supplied with a relay removal tool.

6) Because it can be replaced by a relay output, it can be used either for AC or DC
with larger current capacity.
7) Self-up screws are adopted so that the terminal screws do not fall off.
8) Wiring works have been simplified by the indication on the symbol sheet of the
relay terminal module.
9) Only a DIN rail can be installed.
10)2-wire load can be connected.
