2.5 Wiring 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 FX100 may result.
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 FX100 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 FX100 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 and 3.
• Connect a fuse between 2 A and 15 A in the power supply line. Use a fuse
approved by CSA (for the use in North America) or VDE (for the use in Europe).
• Do not add a switch or fuse to the ground line.
Use a power supply that meets the following conditions:
Except for /P1 model
Item Specification
Rated supply voltage: 100 to 240 VAC
Supply voltage range used: 90 to 132, 180 to 264 VAC
Rated supply voltage frequency: 50/60 Hz
Permitted supply voltage frequency range: 50/60 Hz ± 2%
Maximum power consumption: 25 VA (100 V), 35 VA (240 V)
/P1 model
Item Specification
Rated supply voltage: 24 VDC/AC
Supply voltage range used: 21.6 to 26.4 VDC/AC
Rated supply voltage frequency: 50/60 Hz (for AC)
Permitted supply voltage frequency range: 50/60 Hz ± 2% (for AC)
Maximum power consumption: 17 VA (for DC), 30 VA (for AC)
Note
• Do not use a supply voltage in the range 132 to 180 VAC, as this may have adverse effects
on the measurement accuracy (applies to all models except for the ones with /P1 option).
• The FX100 has no power switch. Use an external switch to turn the power ON and OFF.
