(1) Turn off all the power before wiring.
(2) Do not route electrical wiring and wiring for large-capacity converters and motors or power
wiring in the same wiring duct.
(3) To prevent malfunction due to noise, do not route signal cables and power cables in the
same cable hole.
(4) When running cables in a place where ambient temperature is high or low, use cables suited
for that condition.
(5) When running cables in an atmosphere where hazardous gas or liquid, or oil or solvent is
present, use cables made of materials that can withstand such aggressive conditions.
(6) For wire termination use crimp terminals (M4 screws) with insulating sleeves.
WARNING
As power supply wiring, the following wiring procedure is necessary.
1. Install an external switch or circuit breaker to the power supply.
2. Use an external switch or circuit breaker conforming with IEC 60947-1 or IEC 60947-3.
3. It is recommended that the external switch or circuit breaker be mounted into the equipment
which the product is installed.
4. The external switch or circuit breaker should be installed within the reach of the operator,

4.3 Cable Specifications
WARNING
Use cable with a durable temperature of at least 70°C.
(1) For the wiring, use cables that are appropriate for the environment that the product is
installed in and that have the flame resistance.
(2) When using multicore cables, use the ones with a finished outside diameter of 14 mm or
less.
(3) Analog output cables must have a shield wire, which should be connected to the FG
terminal of the instrument.
(4) For the grounding, use 600 V PVC insulated wires.
