General Precautions When Wiring the Signal Wires

WARNING

• To prevent the possibility of electric shock when wiring, confirm that the

power supply source and the signal source are turned OFF. After making the

connections, secure the terminal cover and do not touch the terminals with your

hands.

• For signal wires on which voltage exceeding 30 VAC/60 VDC is applied relative

to the ground potential or between signals, use reinforced (double) insulation

wires. For all other signal wires, use basic insulation wires. For the withstand

voltage of insulation wires, see the table below.

Applied Voltage (Vrms or VDC) Basic Insulation Double (reinforced) Insulation

0 to 150 1350 Vrms 2700 Vrms

151 to 300 1500 Vrms 3000 Vrms

301 to 600 2210 Vrms 3700 Vrms

• To avoid electric shock when removing the terminal plate for wiring, be sure to

attach the terminal plate before inputting signals. Electric shock or fire can result

if signals are applied to the terminals when the terminal plate is removed from

the input modules.

• To prevent fire, use signal wires of the temperature rating 80°C or better.

CAUTION

• If a large pulling force is applied to the signal wires connected to the terminal

plate, the terminal plate or signal wire may break. To prevent this from

happening, fix all the wiring cables to the installation panel.

• Do not apply a voltage exceeding the value indicated below to the input

terminals of the 10-CH Medium-Speed Universal Input module which attached

the plate with clamp terminals for current. Doing so can damage the modules.

• Maximum input voltage

772081: ±1.5 VDC (continuation)

772082: ±5 VDC (continuation)

772083: ±8 VDC (continuation)

• The MX100 and MW100 are a measurement category II (IEC61010-2-30) and

overvoltage category II (IEC61010-1) instrument.

Wiring Procedure

For information about wiring, see the MX100 Data Acquisition Unit Installation and

Connection Guide (IM MX100-72E) provided with the main module, the MX100 Data

Acquisition Unit User’s Manual (IM MX100-01E) or the MX100 Data Acquisition Unit

User’s Manual (IM MW100-01E) contained in the manual CD-ROM.
