1.5 Handling Precautions

Safety precautions

• Before you use this recorder make sure to read the Safety Precautions on page 2 of
this manual.

• Do not touch the interior of this recorder. For the replacement of parts, please
contact OMEGA Engineering.

• Turn the recorder power switch off as soon as any symptoms of malfunction such as
unusual sound, smell, or smoke yield from the recorder. Also turn the main power
switch off. If a malfunction occurs, contact OMEGA Engineering.

General handling precautions

• The recorder contains many plastic parts. To clean, use a soft, dry cloth. Do not
use chemicals such as benzene or thinner, since these may cause discoloration or
damage.

• Do not bring any objects charged with static electricity near the signal terminals.
This might cause malfunction.

• Do not allow any volatile substances to the front or key panel. Do not allow rubber
or vinyl to remain in contact with the recorder for long periods.

• Whenever the recorder is not used, turn the power switch OFF.

gases, etc.,

Please avoid installing near electro-magnetic objects.

Mounting Methods

1 The recorder has three small square windows lined on the right, left, bottom and top

of the recorder to apply mouting brackets. Remove the plastic inside frames of the
square windows ,as shown in the below illustration, by flipping them out with a
small screwdriver. Don’t let the frames fall inside.

CAUTION

• Take care not to damage the interior of the recorder when flipping the plastic
frames out of the windows. Don’t insert the driver too far.

2 Insert the recorder into the panel-front face (continued on next page).

1-7

Mounting

3 Mount the recorder on a steel panel which thickness is at least 2 mm (and up to 26

mm).
Fix the recorder to the panel using the mounting brackets as shown in below.
Adequate screw tightening torque is approximately 3 to x kg-cm. A pair of mounting
brackets can be applied to the recorder’s top and bottom, or to both side faces.

CAUTION

• A tightening torque exceeding the above-mentioned adequate values may cause
deformation of the recorder case or brackets.

Power Supply Wiring

Wiring

Preparation

WARNING

• To prevent an electric shock, ensure the main power supply is turned off 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 ahould
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 with the following characteristic:

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

Wiring method

1 The rated power supply voltage for the recorder is 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. 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.

5 Cover the terminals with the transparent cover, and secure the screw.

Power Supply Wiring

LN

Functional earthing cord

Power supply wires

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 emission of electromagnetic disturbances, separate the power supply wires from the
other wires at least 0.1 m. Over 0.5 m is recommended.

Wiring

Input Signal Wiring

WARNING

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

CAUTION

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)

• This instrument complies with Installation Category II.

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. To prevent an emission of electro-

magnetic disturbances, separate the input wires from the other wires at least 0.1 m.
Over 0.5 m is recommended.

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.

1-12

1

Wiring

For TC (thermocouple) inputs 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 mm

because it has a large radiation rate.

• Keep the ambient temperature as stable as possible; start/stop of a nearby fan can
considerably affect 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 sensor (RTD) cannot be used essentially in parallel
connection.
