Shock Hazard
When installing the switch between the OUTPUT terminal block and the load, be sure to turn the
POWER switch off and remove the power plug from an outlet or turn off the circuit breaker of
switchboard.
The current rating of the switch must be greater than or equal to the instrument's maximum current.
For the switch circuit, use a two-pole type switch that cuts off L and N wires simultaneously.
Be sure to turn the switch off before connecting the load to the terminal at the load end of the switch.
Do not touch the switch terminal when the output is on.
To prevent the possibility of electric shock, do not touch the output terminal block.
Do not remove the instrument covers. There are no customer-serviceable parts inside. Some circuits
are active and have power briefly after the power switch is turned off.
To prevent electric shock, unplug the unit before cleaning.
For protection from electrical shock, the power cord ground must not be defeated. If only a two-
contact electrical outlet is available, connect the instrument’s chassis ground screw (see above) to a
good earth ground.
This product is an IEC Safety Class I equipment (equipment with a protective conductor terminal). Be
sure to ground (earth) the unit.
Connect the protective conductor terminal to earth ground.
In DC mode, L is at positive potential and N is at negative potential when setting the positive value. The
opposite is true when setting the negative value.
Do not use the terminal block with the terminal cover removed.
Turn off the switchboard circuit breaker before connecting the cord.
This product includes protective earth terminals. To minimize shock hazard, the instrument must be
connected to the AC power mains through a grounded power cable, with the ground wire firmly
connected to an electrical ground (safety ground) at the power outlet. Any interruption of the
protective (grounding) conductor or disconnection of the protective earth terminal will cause a
potential shock hazard that could result in personal injury.
If a capacitor, battery, or similar device is connected as a load in DC mode, voltage remains at the
section connected to the output terminal block even when the output is off until the load energy is
discharged. The discharge time of the internal capacitor when no load is connected is approximately
0.1 seconds. To prevent the possibility of electric shock, do not touch the output terminal block.
