3.4 Connecting the Power Cord
Before Connecting the Power
Make sure that you perform the following steps before connecting the power. Failure to do
so may cause electric shock or damage to the instrument.
WARNING
• Connect the power cord after confirming that the voltage of the power
supply complies to the rated electric power voltage for this instrument.
• Connect the power cord after confirming that the power switch is OFF.
• Always use protective ground to prevent electric shock. Connect the
accessory power cord to a power outlet with grounding terminal.
• Do not use non-grounding extension cords or other measures that defect
the protective grounding.
• Never use an extension cord that does not have protective grounding,
otherwise the protection feature will be negated.
Connecting the Power Cord
1. Make sure that the main power switch is OFF.
2. Plug the power cord into the power connector socket on the rear panel of the instrument.
3. Plug the other end of the power cord into an AC outlet that meets the following
specifications. The AC outlet must be of 3-pin type with a protective grounding
terminal.
