2.4 Connecting the Power Supply
Precautions to Be Taken When Wiring the Power Supply
Make sure to follow the warnings below when wiring the power supply. Otherwise,
electric shock or damage to the CX2000 may result.
WARNING WARNING
• To prevent the possibility of electric shock when wiring, confirm that the power
supply source is turned OFF.
• To prevent the possibility of fire, use a power line or cord that is equivalent to
600 V PVC insulated wire (AWG 18) or better.
• Make sure to ground the protective ground terminal through a grounding
resistance of less than or equal to 100 Ω before turning ON the power.
• Use crimp-on lugs with isolation sleeves (for 4-mm screws) for power supply
wires and protective grounding wires.
• To prevent the possibility of electric shock, make sure to close the cover
(transparent) for the power supply wires.
• Furnish a switch (double-pole type) to separate the CX2000 from the main
power supply in the power supply line. In addition, make sure to indicate that
the switch is a power control for the CX2000 on the switch and the ON/OFF
positions of the switch.
Switch Specifications
Steady-state current rating: 1 A or more, inrush current rating: 60 A or more
Use a switch complied with IEC60947-1, 3.
• Connect a fuse between 2 A and 15 A in the power supply line.
• Do not add a switch or fuse to the ground line.

Note
Do not use a supply voltage in the range 132 to 180 VAC, as this may have adverse effects
on the measurement accuracy.
Wiring Procedure
1. Turn OFF the CX2000 and open the cover (transparent) for the power supply wires.
2. Connect the power cord and the protective ground cord to the power supply
terminals.The proper torque for tightening the screw is 1.4 to 1.5 N·m (12.4 to 13.2
inch·lbs).
