4.2 Cautions on Connections
Observe the following cautions during connections for securing safety and reliability.
1.Feed source power supply
Use a single-phase power supply having a
stable voltage without any waveform distortion
for the purpose of preventing wrong operations.
Add a switch and an overcurrent protective
device (3A) to the feed source power supply
for preventing an electric shock accident
during connection work. This instrument is
not provided with any replaceable
overcurrent protective device.
Turn off the feed source power supply in
advance without fail for preventing an
electric shock accident when the power
supply and input/output terminals are
connected.
2. Separate input/output
connections from a strong
power circuit
Don’t place the input/output cables to be close to
or in parallel with any strong power circuits
including power line. Separate them more than 50
cm from strong power circuits when they are
placed to be close to or in parallel with strong
power circuits.
3. Separate the thermocouple input
terminals from a heat source
For thermocouple inputs, separate the input
terminals from a heat source (a heating body) for a
purpose of reducing a reference junction
compensation error. Don't expose the input terminals
to the radiation of direct sunlight, etc.
4. Separate all connection
cables from noise sources
Separate all connection cables to the instrument from
a noise source as far as possible, otherwise an
unexpected trouble may occur. Take a remedial
measure if the cables cannot be separated from a
noise source due to unavoidable circumstances.
Major noise sources Remedial measures
Electromagnetic switch,
power line having
waveform distortion,
inverter, thyristor regulator
Insert noise filters
between power
terminals and
input/output terminals.
A CR filter is often used.
5.Use crimp style terminals
1) Mount crimp style terminals as connection cables'
termination for preventing the looseness or
disconnection of terminals and a short-circuit failure
between terminals.
2 )For crimp style terminals, use an insulation sleeve for
preventing an electric shock accident.
6. Unused terminals
Don't use any unused terminals for relaying, otherwise
electric circuits may be damaged.

4.3 Power and Protective Conductor Terminals
1. Power terminals and protective
conductor terminal
2. Connection of power terminals
For the connections to power terminals, use a 600V vinyl
insulated cable (IEC 227-3 Note), with the crimp style
terminals and an insulation sleeve.
Note: Use the cords approved by the following standards.
1) IEC 227-3 or 2) ANSI/UL817
3) CSA C22.2 No.21/No.49
3. Connection of protective
conductor terminal
Connect this terminal to the protective conductor of the
power supply equipment without fail. For this connection,
use a cable with a crimp style terminal and an insulation
sleeve.
Grounding wire : A copper wire having a wire diameter of
larger than 2mm2
Turn off the feed source power supply without fail
before connecting the power terminals and protective
conductor terminal for the purpose of preventing an
electric shock accident.
Turn off the feed source power supply
Warning
The power voltage of this instrument is indicated
beside the power terminals. Don't apply any voltage
other than indicated, otherwise a trouble occurs or
malfunction results. If noises are mixed into the power
supply, take a remedial measure, such as the addition
of a noise cut transformer
,
etc.
Be careful with the power voltage and noises.
Caution
A voltage of 100 to 240V AC is applied to the power
terminals after connections. Mount the power
terminal cover without fail after connections for the
purpose of preventing an electric shock accident.

4.4 Measuring Input Terminals
1. Measuring input terminals
Turn off the feed power source for preventing an
electric shock accident.
1) Measuring input terminals are provided at the
lower part of the terminal board.
2) For the connections to input terminals, use
cables with crimp style terminals and an
insulation sleeve.
2. Connections of DC voltage
(current) input
Use a twisted cable for instrumentation as the
input cable for the purpose of suppressing noises.
For current inputs, mount shunt resistors (par.
15.2) to the channels to be measured before
connections.
3. Connections of
thermocouple inputs
Use a thermocouple wire (or extension wire) to
the input terminals of this instrument without
fail. If a copper wire is used halfway, a noticeable
measuring error occurs. Don't use a pair of
thermocouple wires in parallel with other
instruments (controller, etc.) otherwise a trouble
may occur. By influence of signal source
resistance or the like, other instruments
(controllers, etc.) may have indication error.
4. Connections of resistance
thermometer inputs
For the input wire, use a 3-core cable where each
lead wire has an equal resistance value. Don't use
one resistance thermometer in parallel with other
instruments (controller, etc.).
A high voltage may be applied to the measuring input terminals due to common mode noises. The
allowable noise value is lower than 3OVAC or lower than 6OVDC. Make sure that the noises are
lower than the allowable values. Mount the terminal cover after connections for the purpose of
preventing an electric shock accident and protecting the input wires. In case of thermocouple inputs,
an error of the reference junction compensation can be reduced by the terminal cover.

4.5 Alarm Output Terminals
The following connections apply to the instrument with an alarm output function (option) only. There are
three kinds of alarm outputs available: (1) MOS relay 'c' contact output, (2) mechanical relay 'c' contact and
(3) mechanical relay 'a' contact output, which are shipped by the designated outputs. The mechanical relay 'c'
contact output does not conform to the international safety standards.
1. Alarm output terminals
The terminal arrangement depends upon the type of alarm output.
MOS relay and mechanical relay 'a' contact outputs Mechanical relay 'c' contact output
*The international safety standards do not conform.
2. Connections
Turn off the feed power source and buffer relay power supply before starting connections for the purpose of
preventing an electric shock accident.
(1) Connect cables to the load via a buffer relay.
(2) Mount a crimp style terminal with an insulation sleeve to the alarm output terminals before connections.

(It is recommended to mount this element on the ‘a’ side)
*N.O terminal ----- Close relay contact when alarm is on.
N.C terminal ----- Open relay contact when alarm is on.
Connect a load of less than specified (See Remarks 1 and 2) to the alarm output terminals. A buffer relay
power supply is applied to the alarm output terminals after connections and an electric shock accident
occurs if you should touch these terminals. Mount a terminal cover without fail after connections.
An alarm output of this instrument may become defective due to wrong operation, failures, abnormal
inputs, or other troubles. Take a safety measure against an output failure before use as occasion
demands.
