Power Supply Wiring
WARNING
Panel Mount Type
• To prevent electric shock when wiring, ensure the main power supply is turned
OFF.
• To prevent the possibility of fire, use 600 V PVC insulated wire (AWG20 to 16) or
an equivalent wire for power wiring.
• Make sure to earth ground the protective earth terminal through a grounding
resistance less than 100 Ω before turning ON the power.
• Use crimp-on lugs (designed for 4-mm screws) for power and ground wiring
termination.
• To prevent electric shock, make sure to close the transparent cover for the
power supply wires.
• Make sure to provide a power switch (double-pole type) on the power supply line
in order to separate the recorder from the main power supply. Put an indication
on this switch as the breaker on the power supply line for the recorder and
indications of ON and OFF.
Switch specifications
Rated power current: 1 A or more (other than /P1), 3 A or more (/P1 option)
Rated rush current: 60 A or more (other than /P1), 70 A or more (/P1 option)
Complies with IEC 60947-1, 3.
• Connect a fuse in the power supply line.
2 A to 15 A (other than /P1), 4 A to 15 A (/P1 option)
• Do not add a switch or fuse to the ground line.
Portable Type (/H5x Option)
• Ensure that the source voltage matches the rated power supply voltage of the
instrument before connecting the power cord.
• Connect the power cord after checking that the power switch of the portable type
is turned OFF.
• To prevent electric shock or fire, be sure to use the power cord for the portable
type supplied by YOKOGAWA.
• Make sure to connect protective earth grounding to prevent electric shock.
Connect the power cord of the portable type to a three-prong power outlet
equipped with a protective earth terminal.
• Do not use an extension cord that does not have a protective grounding wire.
The protective features of the instrument will be rendered ineffective.
Use a power supply that meets the following conditions:
Item
Power Supply Specifications
(Options Other Than /P1) (/P1 Option)
Rated supply voltage 100 to 240 VAC 24V DC/AC
Allowable power supply voltage range 90 to 132/180 to 264 VAC 21.6 V to 26.4 VDC/AC
Rated power supply frequency 50/60 Hz 50/60 Hz (for AC)
