2.5 Connecting the Power Cable and Turning on the Power
This section describes how to connect the power cable and turn on the power.
No power cord is supplied with the MT100.
Be sure to use a power cord supplied with the desktop case (B-541).
Refer to the warnings below and follow directions when connecting the power cable.
Failure to do so may result in electric shock or damage of the device.
WARNING
• To avoid electric shocks, check that the AC source for the power supply has been turned off.
• To prevent fire, use wires or cables with a performance equivalent to or better than 600V insulated
wires (AWG 20 to 16).
• Before turning on the power, be sure to connect the protective ground terminal to the ground at a
grounding resistance of 50Ω or less.
• For cables to be connected to a power supply and a protective ground terminal, use non-insulated
solderless ring terminals (for 4mm screws) inserted in insulation caps.
• In the power line, provide a switch that can cut off the MT100 from the main power source (double-
pole type). As specifications of the switch, the rated steady-state current must be 1A or larger and the
rated inrush current must be 60A or larger.
• Do not insert a switch or fuse in a grounding line.
• Use a power supply that meets the following conditions.
Power supply must meet the following conditions.
