2.2.2 Power Supply Wiring

(1) The rated power supply voltage for the recorder is follows.

• 100 to 240 V AC
(2) Turn the recorder’s power switch off.
(3) Open the transparent cover of the power terminal after releasing the cover screw.
(4) Connect the power supply wires and the protective ground wire to the terminal.
(5) Cover the terminals with the transparent cover, and secure the screw.

Power Supply Wiring

• To prevent an electric shock, ensure the main power supply is turned off

WARNING

before wiring.

• To prevent fire, use 600 V PVC insulated wire (AWG18) for power and

ground wiring (cross sectional area of 0.83 mm2 or thicker, anti-galvanic
corrosion finish, insulation thickness should be more than 0.8 mm, insulation
resistance should be more than 50 M /Km at 20˚C, approved EN60 320
(VDE0625) ), or equivalent cables.

• Connect the protective grounding wire to the earth through grounding

resistance less than 100 before turning on the power.

• Use crimp-on lugs (for 4 mm screws) with insulation sleeves.

• To prevent an electric shock, cover the power terminals certainly with the

transparent cover.

• Make sure to apply a power switch near by with the following characteristic:

rated power current > 1A
rated rush current > 60A
fuse (s) of 2A to 15A is (are) necessary.

Protective grounding wire

NOTE • Do not apply a power supply in the range from 132 V to 180 V AC. Doing so

might affect the measuring accuracy.

• To prevent an emission of electromagnetic disturbances, separate the power

supply wires from the other wires at least 0.1 m. Over 0.5 m is
recommended.

2 - 5

2.2.3 Input Signal Wiring

(1) Turn off the recorder power switch.
(2) Remove the transparent cover for the input signal terminals.
(3) Connect the input signal wires to the terminals.
(4) Attach the cover on the terminals, and secure the screws.

It is recommended to use the crimp-on lugs (for 4 mm screws) with insulation sleeves
for lead wire ends, but they are not required for thermocouples (TC).

Crimp-On Lugs

Suggestions to minimize noise pickup:

• Separate the measuring-signal wires from power lines and grounding lines.

• It is desirable that the measuring object is not a noise source; if not, insulate it from

the measuring-signal wires and ground the object.

• It is recommended to use shielded wires to minimize noise pickup from an
electrostatic induction source. The shields are connected to the recorder’s grounding
terminal, if necessary. In that case, avoid two-point grounding.

• To minimize the noize from an electrostatic induction noise, twist the measuring
wires (a pair of wires) in short and equal intervals.

• The grounding line must have low resistance.

!

WARNING

CAUTION

In case of using a thermocouple (TC), the recorder is equipped with a reference junction
compensator, so the ambient temperature around the recorder’s terminal board should
be kept as stable as possible.

• Cover the input terminals with the transparent cover.

• Do not use a large-diameter wire (cross sectional area of more than 0.5 mm2) because

it has a large radiation rate.

• Keep the ambient temperature as stable as possible; start/stop of a nearby fan affects
the temperature.

If input signal wires are connected to two or more receivers with parallel connection,
measured values sometimes affect each other. The following notes should be observed
for parallel connection:

• Ground each receiver at the same point.

• Do not turn on/off the power of a receiver while other receivers are in measuring

operation.

• A resistance temperature detector (RTD) cannot be used essentially in parallel
connection.

To prevent an electric shock, ensure the main power switch is turned off when
wiring.

Do not apply inputs exceeding the rated range as follows to prevent the
recorder from damage:

• Maximum input voltage
±10 V DC for TC, and for the voltage range of 2 V DC or less
±30 V DC for the voltage range of 6 to 20 V DC

• Maximum common mode voltage
250 V AC rms (50/60 Hz)

• The installation of each input is Category II.

NOTE • To prevent an emission of electromagnetic disturbances, separate the input

wires from the other wires at least 0.1 m. Over 0.5 m is recommended.
