2.5 Power Supply Wiring
Precautions to Be Taken While Wiring the Power Supply
Make sure to follow the warnings below when wiring the power supply. To prevent electric shock and damage to
the recorder, observe the following warnings.
WARNING
• 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 (JISC3307) 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
Rated rush current: 60 A or more
Use a switch complied with IEC 60947-1, 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:
