Installation Environment
WARNING: Installation work, wiring, and connections must be
performed by a person with knowledge in instrumentation.
Always ground the system. Never apply power until all wiring
work and connection work has been completed. If this isn't
followed, there's a possibility of electrocution.
WARNING: Be sure to adhere to the following guidelines:
• Before touching this unit, be sure to touch a metal section
near by to discharge any static electricity. The device may
be damaged if exposed to static electricity from your body.
• Before applying power, make sure that all wiring is properly
connected. There's a possibility of damage to the unit and
fire if improperly connected.
• Install this unit away from motors and relays.
• Install the input/output signal cables away from power and
control system cables. Noise occurring from the motor or
relay can adversely affect the measurement value. We
recommend using separate wiring ducts.
• Do not pull or bend the sensor and extension cables with
excessive force. The conductor in the cable may get cut off.
• The allowable tension of the sensor cables and extension
cables is 98.1 N•m (10 kgf•m).
• The allowable bend radius is:
- Without armored cable: 30 mm (1.18 in.)
- With armored cable: 50 mm (1.97 in.)
• After completing the installation, verify that all connections
are correct and tight before powering the system.
