Close the ferrite core. Avoid catching the wire on the ferrite core. Attach the ferrite core within 10 cm from the
OUTPUT terminal block (as indicated by the arrows below). Lock the ferrite core securely in place. To avoid mov-
ing the ferrite core, attach the cable tie to fix the position of the ferrite core.
Note that the L and N terminals of the OUTPUT terminal block are isolated from the AC power line, and the polarity
does not constitute a problem in terms of safety. Grounding can be furnished using L or N.
When the load is located at a distance from the instrument
The load may be away from the instrument. You can use remote control to turn the output off, but not to turn off
the POWER switch. If the load is at a distance from the instrument, install a switch between the OUTPUT terminal
block and the load to prevent electric shock, then turn the switch off.
Possible electric shock
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.
