Shock Hazard
Before making any load or sense connections be sure to turn the POWER switch off and
remove the power plug from an outlet or turn off the circuit breaker at the switchboard.
When the power switch is turned off while the output is on, residual voltage still remains
at the output terminals.
Do not touch the output terminal block for at least 20 seconds after the power switch is
tuned off.
When installing the switch between the OUTPUT terminal block and the load, be sure to
turn off the circuit breaker of the switchboard.
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 or the output terminal when the output is on.
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.
Always turn off the circuit breaker at the switchboard before cleaning.
Always ensure that the power cord ground is connected.
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, the Line (P1) terminals are at positive potential and the Neutral terminals are
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.
