5.3 Connection of power and protective conductor terminals
1) Power and protective conductor terminals
2) Connection of power terminals
For connection to the power terminals, use a 600 V
PVC insulated cable terminated by the crimp style
terminals with insulation sleeve.
Note) Use the cords approved by the following
standards.
(1) IEC 227-3
(2) ANSI/UL817
(3) CSA C22.2 No.21/49
3) Connection of protective conductor
terminal
Be sure to connect this terminal to the protective
conductor of the power supply facility. For this
connection, use a cable terminated by the crimp style
terminals with insulation sleeve.
• Grounding wire:
Copper wire 2 mm
2
or more (green/yellow)
■
Turn off the power supply
Be sure to turn off the power supply before connecting the cable to the power supply and
protective conductor terminals to prevent an electric shock.
Warning
■
Be careful with the power voltage and
noise
The power voltage of this instrument is indicated
beside the power terminals.
Don’t apply any voltage other than indicated;
otherwise a malfunction may result.
If noise is generated at the power supply,
provide a noise reduction transformer, etc.
Caution
This indication conforms to the CSA standard,
Canada. The live side of the single-phase AC
power supply is indicated as L, and the neutral
side is indicated as N. Observe the L and N
connections for obtaining satisfactory
performance.

mark at power terminals
A voltage of 100 to 240 V AC is applied to the
power terminals after connection. Be sure to
mount the power terminal cover to prevent an
electric shock.
